nvidia-smi(1) NVSMI nvidia-smi(1)
NAME
nvidia-smi - NVIDIA System Management Interface program
SYNOPSIS
nvidia-smi [OPTION1 [ARG1]] [OPTION2 [ARG2]] ...
DESCRIPTION
nvidia-smi (also NVSMI) provides monitoring and management capabilities
for each of NVIDIA's Tesla, Quadro, GRID and GeForce devices from Fermi
and higher architecture families. GeForce Titan series devices are
supported for most functions with very limited information provided for
the remainder of the Geforce brand. NVSMI is a cross platform tool that
supports all standard NVIDIA driver-supported Linux distros, as well as
64bit versions of Windows starting with Windows Server 2008 R2. Metrics
can be consumed directly by users via stdout, or provided by file via
CSV and XML formats for scripting purposes.
Note that much of the functionality of NVSMI is provided by the
underlying NVML C-based library. See the NVIDIA developer website link
below for more information about NVML. NVML-based python bindings are
also available.
The output of NVSMI is not guaranteed to be backwards compatible.
However, both NVML and the Python bindings are backwards compatible,
and should be the first choice when writing any tools that must be
maintained across NVIDIA driver releases.

Python bindings: http://pypi.python.org/pypi/nvidia-ml-py/
OPTIONS
GENERAL OPTIONS
-h, --help
Print usage information and exit.
--version
Print version information and exit.
LIST OPTIONS
-L, --list-gpus
List each of the NVIDIA GPUs in the system, along with their UUIDs.
-B, --list-excluded-gpus
List each of the excluded NVIDIA GPUs in the system, along with their
UUIDs.
SUMMARY OPTIONS
Show a summary of GPUs connected to the system.
-col, --columns
Show a summary of GPUs connected to the system in a multi-column
format.
[any one of]
-i, --id=ID
Target a specific GPU.
-f FILE, --filename=FILE
Log to the specified file, rather than to stdout.
-l SEC, --loop=SEC
Probe until Ctrl+C at specified second interval.
QUERY OPTIONS
-q, --query
Display GPU or Unit info. Displayed info includes all data listed in
the (GPU ATTRIBUTES) or (UNIT ATTRIBUTES) sections of this document.
Some devices and/or environments don't support all possible
information. Any unsupported data is indicated by a "N/A" in the
output. By default information for all available GPUs or Units is
displayed. Use the -i option to restrict the output to a single GPU or
Unit.
[plus optionally]
-u, --unit
Display Unit data instead of GPU data. Unit data is only available for
NVIDIA S-class Tesla enclosures.
-i, --id=ID
Display data for a single specified GPU or Unit. The specified id may
be the GPU/Unit's 0-based index in the natural enumeration returned by
the driver, the GPU's board serial number, the GPU's UUID, or the GPU's
PCI bus ID (as domain:bus:device.function in hex). It is recommended
that users desiring consistency use either UUID or PCI bus ID, since
device enumeration ordering is not guaranteed to be consistent between
reboots and board serial number might be shared between multiple GPUs
on the same board.
-f FILE, --filename=FILE
Redirect query output to the specified file in place of the default
stdout. The specified file will be overwritten.
-x, --xml-format
Produce XML output in place of the default human-readable format. Both
GPU and Unit query outputs conform to corresponding DTDs. These are
available via the --dtd flag.
--dtd
Use with -x. Embed the DTD in the XML output.
--debug=FILE
Produces an encrypted debug log for use in submission of bugs back to
NVIDIA.
-d TYPE, --display=TYPE
Display only selected information: MEMORY, UTILIZATION, ECC,
TEMPERATURE, POWER, CLOCK, COMPUTE, PIDS, PERFORMANCE,
SUPPORTED_CLOCKS, PAGE_RETIREMENT, ACCOUNTING, ENCODER_STATS,
SUPPORTED_GPU_TARGET_TEMP, VOLTAGE, FBC_STATS, ROW_REMAPPER,
GSP_FIRMWARE_VERSION, POWER_SMOOTHING, POWER_PROFILES. Flags can be
combined with comma e.g. "MEMORY,ECC". Sampling data with max, min and
avg is also returned for POWER, UTILIZATION and CLOCK display types.
Doesn't work with -u/--unit or -x/--xml-format flags.
-l SEC, --loop=SEC
Continuously report query data at the specified interval, rather than
the default of just once. The application will sleep in-between
queries. Note that on Linux ECC error or Xid error events will print
out during the sleep period if the -x flag was not specified. Pressing
Ctrl+C at any time will abort the loop, which will otherwise run
indefinitely. If no argument is specified for the -l form a default
interval of 5 seconds is used.
-lms ms, --loop-ms=ms
Same as -l,--loop but in milliseconds.

Display data for a single specified GPU. The specified id may be the
GPU's 0-based index in the natural enumeration returned by the driver,
the GPU's board serial number, the GPU's UUID, or the GPU's PCI bus ID
(as domain:bus:device.function in hex). It is recommended that users
desiring consistency use either UUID or PCI bus ID, since device
enumeration ordering is not guaranteed to be consistent between reboots
and board serial number might be shared between multiple GPUs on the
same board.
-f FILE, --filename=FILE
Redirect query output to the specified file in place of the default
stdout. The specified file will be overwritten.
-l SEC, --loop=SEC
Continuously report query data at the specified interval, rather than
the default of just once. The application will sleep in-between
queries. Note that on Linux ECC error or Xid error events will print
out during the sleep period if the -x flag was not specified. Pressing
Ctrl+C at any time will abort the loop, which will otherwise run
indefinitely. If no argument is specified for the -l form a default
interval of 5 seconds is used.
-lms ms, --loop-ms=ms
Same as -l,--loop but in milliseconds.
DEVICE MODIFICATION OPTIONS
[any one of]
-pm, --persistence-mode=MODE
Set the persistence mode for the target GPUs. See the (GPU ATTRIBUTES)
section for a description of persistence mode. Requires root. Will
impact all GPUs unless a single GPU is specified using the -i argument.
The effect of this operation is immediate. However, it does not persist
across reboots. After each reboot persistence mode will default to
"Disabled". Available on Linux only.
-e, --ecc-config=CONFIG
Set the ECC mode for the target GPUs. See the (GPU ATTRIBUTES) section
for a description of ECC mode. Requires root. Will impact all GPUs
unless a single GPU is specified using the -i argument. This setting
takes effect after the next reboot and is persistent.
-p, --reset-ecc-errors=TYPE
Reset the ECC error counters for the target GPUs. See the (GPU
ATTRIBUTES) section for a description of ECC error counter types.
Available arguments are 0\|VOLATILE or 1\|AGGREGATE. Requires root.
Will impact all GPUs unless a single GPU is specified using the -i
argument. The effect of this operation is immediate. Clearing aggregate
counts is not supported on Ampere+
-c, --compute-mode=MODE
Set the compute mode for the target GPUs. See the (GPU ATTRIBUTES)
section for a description of compute mode. Requires root. Will impact
all GPUs unless a single GPU is specified using the -i argument. The
effect of this operation is immediate. However, it does not persist
across reboots. After each reboot compute mode will reset to "DEFAULT".
-dm TYPE, --driver-model=TYPE
-fdm TYPE, --force-driver-model=TYPE
Enable or disable TCC driver model. For Windows only. Requires
administrator privileges. -dm will fail if a display is attached, but
-fdm will force the driver model to change. Will impact all GPUs unless
a single GPU is specified using the -i argument. A reboot is required
for the change to take place. See Driver Model for more information on
Windows driver models. An error message indicates that retrieving the
field failed.
--gom=MODE
Set GPU Operation Mode: 0/ALL_ON, 1/COMPUTE, 2/LOW_DP Supported on
GK110 M-class and X-class Tesla products from the Kepler family. Not
supported on Quadro and Tesla C-class products. LOW_DP and ALL_ON are
the only modes supported on GeForce Titan devices. Requires
administrator privileges. See GPU Operation Mode for more information
about GOM. GOM changes take effect after reboot. The reboot requirement
might be removed in the future. Compute only GOMs don't support WDDM
(Windows Display Driver Model)
-r, --gpu-reset
Trigger a reset of one or more GPUs. Can be used to clear GPU HW and SW
state in situations that would otherwise require a machine reboot.
Typically useful if a double bit ECC error has occurred. Optional -i
switch can be used to target one or more specific devices. Without this
option, all GPUs are reset. Requires root. There can't be any
applications using these devices (e.g. CUDA application, graphics
application like X server, monitoring application like other instance
of nvidia-smi). There also can't be any compute applications running on
any other GPU in the system if individual GPU reset is not feasible.
Starting with the NVIDIA Ampere architecture, GPUs with NVLink
connections can be individually reset. On Ampere NVSwitch systems,
Fabric Manager is required to facilitate reset. On Hopper and later
NVSwitch systems, the dependency on Fabric Manager to facilitate reset
is removed.
If Fabric Manager is not running, or if any of the GPUs being reset are
based on an architecture preceding the NVIDIA Ampere architecture, any
GPUs with NVLink connections to a GPU being reset must also be reset in
the same command. This can be done either by omitting the -i switch, or
using the -i switch to specify the GPUs to be reset. If the -i option
does not specify a complete set of NVLink GPUs to reset, this command
will issue an error identifying the additional GPUs that must be
included in the reset command.
Specific details are outlined in the tables below:
NVSwitch systems:
GPU Family | Fabric Manager running | Fabric Manager not running
------------|------------------------------|------------------------------
Pre-Ampere | All PEER connected GPUs must | All PEER connected GPUs must
| be reset in same command. | be reset in same command
Ampere+ | Each GPU can be reset | All PEER connected GPUs must
| individually | be reset in same command
Direct connected NVLink systems: (FM is not supported, as no NVSwitch
HW is present)
GPU Family | Capabilities
------------|-------------------------------------------------------
Pre-Ampere | All PEER connected GPUs must be reset in same command
Ampere+ | Each GPU can be reset individually
GPU reset is not guaranteed to work in all cases. It is not recommended
for production environments at this time. In some situations there may
be HW components on the board that fail to revert back to an initial
state following the reset request. This is more likely to be seen on
Fermi-generation products vs. Kepler, and more likely to be seen if the
reset is being performed on a hung GPU.
Following a reset, it is recommended that the health of each reset GPU
be verified before further use. If any GPU is not healthy a complete
reset should be instigated by power cycling the node.
Reset triggered without extra arguments, will be a default Function
Level Reset (FLR). To issue a Bus Reset, use -r bus. For certain
platforms only Function Level Reset is possible.
GPU reset operation will not be supported on MIG enabled vGPU guests.

also use be a singular desired clock value (e.g. <GpuClockValue>).
Optionally, --mode can be supplied to specify the clock locking modes.
Supported on Volta+. Requires root.
--mode=0 (Default)
This mode is the default clock locking mode and provides
the highest possible frequency accuracies supported by
the hardware.
--mode=1 The clock locking algorithm leverages close loop
controllers to achieve frequency accuracies with
improved perf per watt for certain class of
applications. Due to convergence latency of close loop
controllers, the frequency accuracies may be slightly
lower than default mode 0.

that defines the range of desired locked Memory clock speed in MHz.
Input can also be a singular desired clock value (e.g.
<MemClockValue>). Requires root. Note: this option does not work on
GPUs based on NVIDIA Hopper architectures; to lock memory clocks on
those systems use --lock-memory-clocks-deferred instead.
-rgc, --reset-gpu-clocks

GPU ATTRIBUTES
The following list describes all possible data returned by the -q
device query option. Unless otherwise noted all numerical results are
base 10 and unitless.
Timestamp
The current system timestamp at the time nvidia-smi was invoked. Format
is "Day-of-week Month Day HH:MM:SS Year".
Driver Version
The version of the installed NVIDIA display driver. This is an
alphanumeric string.
CUDA Version
The version of the CUDA toolkit installed on the system. This is an
alphanumeric string.
Attached GPUs
The number of NVIDIA GPUs in the system.
Product Name
The official product name of the GPU. This is an alphanumeric string.
For all products.
Product Brand
The official brand of the GPU. This is an alphanumeric string. For all
products.
Product Architecture
The official architecture name of the GPU. This is an alphanumeric
string. For all products.
Display Mode
This field is deprecated, and will be removed in a future release.
Display Attached
A flag that indicates whether a physical display (e.g. monitor) is
currently connected to any of the GPU's connectors. "Yes" indicates an
attached display. "No" indicates otherwise.
Display Active
A flag that indicates whether a display is initialized on the GPU's
(e.g. memory is allocated on the device for display). Display can be
active even when no monitor is physically attached. "Enabled" indicates
an active display. "Disabled" indicates otherwise.
Persistence Mode
A flag that indicates whether persistence mode is enabled for the GPU.
Value is either "Enabled" or "Disabled". When persistence mode is
enabled the NVIDIA driver remains loaded even when no active clients,
such as X11 or nvidia-smi, exist. This minimizes the driver load
latency associated with running dependent apps, such as CUDA programs.
For all CUDA-capable products. Linux only.
Addressing Mode
A field that indicates which addressing mode is currently active. The
value is "ATS" or "HMM" or "None". When the mode is "ATS", system
allocated memory like malloc is addressable from the GPU via Address
Translation Services. This means there is effectively a single set of
page tables used by both the CPU and the GPU. When the mode is "HMM",
system allocated memory like malloc is addressable from the GPU via
software-based mirroring of the CPU's page tables, on the GPU. When the
mode is "None", neither ATS nor HMM is active. Linux only.
MIG Mode
MIG Mode configuration status
Current MIG mode currently in use - NA/Enabled/Disabled
Pending Pending configuration of MIG Mode - Enabled/Disabled
Accounting Mode
A flag that indicates whether accounting mode is enabled for the GPU.
Value is either "Enabled" or "Disabled". When accounting is enabled
statistics are calculated for each compute process running on the GPU.
Statistics can be queried during the lifetime or after termination of
the process. The execution time of process is reported as 0 while the
process is in running state and updated to actual execution time after
the process has terminated. See --help-query-accounted-apps for more
info.
Accounting Mode Buffer Size
Returns the size of the circular buffer that holds list of processes
that can be queried for accounting stats. This is the maximum number of
processes that accounting information will be stored for before
information about oldest processes will get overwritten by information
about new processes.
Driver Model
On Windows, the TCC and WDDM driver models are supported. The driver
model can be changed with the (-dm) or (-fdm) flags. The TCC driver
model is optimized for compute applications. I.E. kernel launch times
will be quicker with TCC. The WDDM driver model is designed for
graphics applications and is not recommended for compute applications.
Linux does not support multiple driver models, and will always have the
value of "N/A".
Current The driver model currently in use. Always "N/A" on
Linux.
Pending The driver model that will be used on the next reboot.
Always "N/A" on Linux.
Serial Number
This number matches the serial number physically printed on each board.
It is a globally unique immutable alphanumeric value.
GPU UUID
This value is the globally unique immutable alphanumeric identifier of
the GPU. It does not correspond to any physical label on the board.
GPU PDI
This value is the Per Device Identifier of the GPU. It is a 64-bit
value that provides uniqueness guarantee for the GPU.
Minor Number
The minor number for the device is such that the Nvidia device node
file for each GPU will have the form /dev/nvidia[minor number].
Available only on Linux platform.
VBIOS Version
The BIOS of the GPU board.
MultiGPU Board
Whether or not this GPU is part of a multiGPU board.

Module Id
ID of this GPU within the node.
GPU Fabric GUID
Fabric ID for this GPU.
Inforom Version
Version numbers for each object in the GPU board's inforom storage. The
inforom is a small, persistent store of configuration and state data
for the GPU. All inforom version fields are numerical. It can be useful
to know these version numbers because some GPU features are only
available with inforoms of a certain version or higher.
If any of the fields below return Unknown Error additional Inforom
verification check is performed and appropriate warning message is
displayed.
Image Version Global version of the infoROM image. Image version just
like VBIOS version uniquely describes the exact version
of the infoROM flashed on the board in contrast to
infoROM object version which is only an indicator of
supported features.

The "Compute" mode is designed for running only compute tasks. Graphics
operations are not allowed.
The "Low Double Precision" mode is designed for running graphics
applications that don't require high bandwidth double precision.
GOM can be changed with the (--gom) flag.
Supported on GK110 M-class and X-class Tesla products from the Kepler
family. Not supported on Quadro and Tesla C-class products. Low Double
Precision and All On modes are the only modes available for supported
GeForce Titan products.

Requested functionality has been deprecated
GPU Recovery Action
Action to take to clear fault that previously happened. It is not
intended for determining which fault triggered recovery action.
Possible values: None, Reset, Reboot, Drain P2P, Drain and Reset
None
No recovery action needed
Reset
Example scenario - Uncontained HBM/SRAM UCE
The GPU has encountered a fault that requires a reset to recover.
Terminate all GPU processes, reset the GPU using 'nvidia-smi -r', and
the GPU can be used again by starting new GPU processes.
Reboot
Example scenario - UVM fatal error
The GPU has encountered a fault may have left the OS in an inconsistent
state.
Reboot the operating system to restore the OS back to a consistent
state.
Node reboot required.
Application cannot restart without node reboot
OS warm reboot is sufficient (no need for AC/DC cycle)
Drain P2P
Example scenario - N/A

to be quiesced.
Terminate all GPU processes that conduct peer-to-peer traffic and
disable UVM persistence mode.
Disable job scheduling (no new jobs), stop all applications when
convenient, if persistence mode is enabled, disable it
Once all peer-to-peer traffic are drained, query
NVML_FI_DEV_GET_GPU_RECOVERY_ACTION again, which will return one of the
other actions.
If still DRAIN_P2P, then GPU reset.
Drain and Reset
Example scenario - Contained HBM UCE
Reset Recommended.
The GPU has encountered a fault that results the GPU to temporarily
operate at a reduced capacity, such as part of its frame buffer memory
being offlined, or some of its MIG partitions down.
No new work should be scheduled on the GPU, but existing work that
didn't get affected are safe to continue until they finish or reach a
good checkpoint.
Safe to restart application (memory capacity will be reduced due to
dynamic page offlining), but need to eventually reset (to get row
remap).
Asserted only for UCE row remaps.
After all existing work have drained, reset the GPU to regain its full
capacity.

at. This value may exceed 100% in certain cases. Note: The reported
speed is the intended fan speed. If the fan is physically blocked and
unable to spin, this output will not match the actual fan speed. Many
parts do not report fan speeds because they rely on cooling via fans in
the surrounding enclosure. For all discrete products with dedicated
fans.

The current performance state for the GPU. States range from P0
(maximum performance) to P12 (minimum performance).
Clocks Event Reasons
Retrieves information about factors that are reducing the frequency of
clocks.
If all event reasons are returned as "Not Active" it means that clocks
are running as high as possible.
Idle This option is deprecated and will be removed in a
future CUDA release. Nothing is running on the GPU and
the clocks are dropping to Idle state.
Application Clocks Setting
This option is deprecated and will be removed in a
future CUDA release. GPU clocks are limited by
applications clocks setting. E.g. can be changed using
nvidia-smi --applications-clocks=<Desired Clock Freq in
MHz>
SW Power Cap SW Power Scaling algorithm is reducing the clocks below
requested clocks because the GPU is consuming too much
power. E.g. SW power cap limit can be changed with
nvidia-smi --power-limit=<Power Limit Value in W>
HW Slowdown This option will be removed a future CUDA release. HW
Slowdown is engaged, reducing the core clocks by a
factor of 2 or more. It is active if either HW Thermal
Slowdown or HW Power Brake are active.
HW Thermal Slowdown
HW Thermal Slowdowns are reducing the core clocks by a
factor of 2 or more due to temperature being too high.
HW Power Brake External Power Brake Assertion is triggered (e.g. by the
system power supply).
Sync Boost This GPU has been added to a Sync boost group with
nvidia-smi or DCGM in order to maximize performance per
watt. All GPUs will be limited by the frequency which
can be achieved by the slowest GPU. Look at the throttle
reasons for other GPUs in the system to see why those
GPUs are holding this one at lower clocks.
SW Thermal Slowdown
SW Thermal capping algorithm is reducing clocks below
requested clocks because GPU temperature is higher than
Max Operating Temp
Display Clock Setting

triggered (e.g. by the system power supply).
Sparse Operation Mode
A flag that indicates whether sparse operation mode is enabled for the
GPU. Value is either "Enabled" or "Disabled". Reported as "N/A" if not
supported.
FB Memory Usage
On-board frame buffer memory information. Reported total memory can be
affected by ECC state. If ECC does affect the total available memory,
memory is decreased by several percent, due to the requisite parity
bits. The driver may also reserve a small amount of memory for internal
use, even without active work on the GPU. On systems where GPUs are
NUMA nodes, the accuracy of FB memory utilization provided by nvidia-
smi depends on the memory accounting of the operating system. This is
because FB memory is managed by the operating system instead of the
NVIDIA GPU driver. Typically, pages allocated from FB memory are not
released even after the process terminates to enhance performance. In
scenarios where the operating system is under memory pressure, it may
resort to utilizing FB memory. Such actions can result in discrepancies
in the accuracy of memory reporting. For all products.
Total Total size of FB memory.
Reserved Reserved size of FB memory.
Used Used size of FB memory.
Free Available size of FB memory.
BAR1 Memory Usage
BAR1 is used to map the FB (device memory) so that it can be directly
accessed by the CPU or by 3rd party devices (peer-to-peer on the PCIe
bus).
Total Total size of BAR1 memory.
Used Used size of BAR1 memory.
Free Available size of BAR1 memory.
Compute Mode
The compute mode flag indicates whether individual or multiple compute
applications may run on the GPU.
"Default" means multiple contexts are allowed per device.
"Exclusive Process" means only one context is allowed per device,
usable from multiple threads at a time.
"Prohibited" means no contexts are allowed per device (no compute
apps).
"EXCLUSIVE_PROCESS" was added in CUDA 4.0. Prior CUDA releases
supported only one exclusive mode, which is equivalent to
"EXCLUSIVE_THREAD" in CUDA 4.0 and beyond.
For all CUDA-capable products.
Utilization
Utilization rates report how busy each GPU is over time, and can be
used to determine how much an application is using the GPUs in the
system. Note: On MIG-enabled GPUs, querying the utilization of encoder,
decoder, jpeg, ofa, gpu, and memory is not currently supported.
Note: During driver initialization when ECC is enabled one can see high
GPU and Memory Utilization readings. This is caused by ECC Memory
Scrubbing mechanism that is performed during driver initialization.
GPU Percent of time over the past sample period during which
one or more kernels was executing on the GPU. The sample
period may be between 1 second and 1/6 second depending
on the product.
Memory Percent of time over the past sample period during which
global (device) memory was being read or written. The
sample period may be between 1 second and 1/6 second
depending on the product.
Encoder Percent of time over the past sample period during which
the GPU's video encoder was being used. The sampling

operating under.
Pending The DRAM Encryption mode that the GPU will operate under
after the next reboot.

Inforom ECC object version 1.0 or higher.
Current The ECC mode that the GPU is currently operating under.
Pending The ECC mode that the GPU will operate under after the
next reboot.
ECC Errors
NVIDIA GPUs can provide error counts for various types of ECC errors.
Some ECC errors are either single or double bit, where single bit
errors are corrected and double bit errors are uncorrectable. Texture
memory errors may be correctable via resend or uncorrectable if the
resend fails. These errors are available across two timescales
(volatile and aggregate). Single bit ECC errors are automatically
corrected by the HW and do not result in data corruption. Double bit
errors are detected but not corrected. Please see the ECC documents on
the web for information on compute application behavior when double bit
errors occur. Volatile error counters track the number of errors
detected since the last driver load. Aggregate error counts persist
indefinitely and thus act as a lifetime counter.
A note about volatile counts: On Windows this is once per boot. On
Linux this can be more frequent. On Linux the driver unloads when no
active clients exist. Hence, if persistence mode is enabled or there is
always a driver client active (e.g. X11), then Linux also sees per-boot
behavior. If not, volatile counts are reset each time a compute app is
run.
Tesla and Quadro products pre-volta can display total ECC error counts,
as well as a breakdown of errors based on location on the chip. The
locations are described below. Location-based data for aggregate error
counts requires Inforom ECC object version 2.0. All other ECC counts
require ECC object version 1.0.
Device Memory Errors detected in global device memory.
Register File Errors detected in register file memory.
L1 Cache Errors detected in the L1 cache.
L2 Cache Errors detected in the L2 cache.
Texture Memory Parity errors detected in texture memory.
Total Total errors detected across entire chip. Sum of Device
Memory, Register File, L1 Cache, L2 Cache and Texture
Memory.
On Turing the output is such:
SRAM Correctable
Number of correctable errors detected in any of the
SRAMs
SRAM Uncorrectable
Number of uncorrectable errors detected in any of the
SRAMs
DRAM Correctable
Number of correctable errors detected in the DRAM
DRAM Uncorrectable
Number of uncorrectable errors detected in the DRAM
On Ampere+ The categorization of SRAM errors has been expanded upon.
SRAM errors are now categorized as either parity or SEC-DED (single
error correctable/double error detectable) depending on which unit hit
the error. A histogram has been added that categorizes what unit hit
the SRAM error. Additionally a flag has been added that indicates if
the threshold for the specific SRAM has been exceeded.

If one of the repair flags is pending, check the GPU Recovery action
and take the appropriate steps.
Channel Repair Pending
Indicates if a Channel repair is pending
TPC Repair Pending
Indicates if a TPC repair is pending
Page Retirement
NVIDIA GPUs can retire pages of GPU device memory when they become
unreliable. This can happen when multiple single bit ECC errors occur
for the same page, or on a double bit ECC error. When a page is
retired, the NVIDIA driver will hide it such that no driver, or
application memory allocations can access it.
Double Bit ECC The number of GPU device memory pages that have been
retired due to a double bit ECC error.
Single Bit ECC The number of GPU device memory pages that have been
retired due to multiple single bit ECC errors.
Pending Checks if any GPU device memory pages are pending blacklist on
the next reboot. Pages that are retired but not yet blacklisted can
still be allocated, and may cause further reliability issues.
Row Remapper
NVIDIA GPUs can remap rows of GPU device memory when they become
unreliable. This can happen when a single uncorrectable ECC error or
multiple correctable ECC errors occur on the same row. When a row is
remapped, the NVIDIA driver will remap the faulty row to a reserved
row. All future accesses to the row will access the reserved row
instead of the faulty row. This feature is available on Ampere+
Correctable Error The number of rows that have been remapped due to
correctable ECC errors.
Uncorrectable Error The number of rows that have been remapped due to
uncorrectable ECC errors.
Pending Indicates whether or not a row is pending remapping. The GPU
must be reset for the remapping to go into effect.
Remapping Failure Occurred Indicates whether or not a row remapping has
failed in the past.
Bank Remap Availability Histogram Each memory bank has a fixed number
of reserved rows that can be used for row remapping. The histogram will
classify the remap availability of each bank into Maximum, High,
Partial, Low and None. Maximum availability means that all reserved
rows are available for remapping while None means that no reserved rows
are available. Correctable row remappings don't count towards the
availability histogram since row remappings due to correctable row
remappings can be evicted by an uncorrectable row remapping.
Temperature
Readings from temperature sensors on the board. All readings are in
degrees C. Not all products support all reading types. In particular,
products in module form factors that rely on case fans or passive
cooling do not usually provide temperature readings. See below for
restrictions.
T.Limit: The T.Limit sensor measures the current margin in degree
Celsius to the maximum operating temperature. As such it is not an
absolute temperature reading rather a relative measurement.
Not all products support T.Limit sensor readings.
When supported, nvidia-smi reports the current T.Limit temperature as a
signed value that counts down. A T.Limit temperature of 0 C or lower
indicates that the GPU may optimize its clock based on thermal
conditions. Further, when the T.Limit sensor is supported, available
temperature thresholds are also reported relative to T.Limit (see
below) instead of absolute measurements.

clocks due to thermal conditions, in order to cool.
GPU Slowdown T.Limit Temp
The T.Limit temperature at or below which GPU HW may
optimize its clocks for thermal conditions. Since this
clock adjustment can only triggered by the maximum GPU
temperature it is possible for the current T.Limit to be
more negative than this threshold.

The temperature at which GPU SW will optimize its clock
for thermal conditions.
GPU Max Operating T.Limit Temp

clocks for thermal conditions. Only available on
supported devices.

management is enabled, the Module limits power draw under load to fit
within a predefined power envelope by manipulating the current
performance state. Supported on Hopper and newer datacenter products.

This value is calculated by doing TMP Ceiling * (% TMP
FLoor value).

watts. This is the power floor that is applied during
active workload periods on the GPU when primary floor
activation window multiplier is set to a non-zero value.

accepted by the driver specified in watts. This is a
static field.
Min Primary Floor Activation Point
This is the minimum absolute raw value specified in
watts that the driver will use for switching between
primary and secondary floor. This point is calculated as
'secondary power floor + primary floor activation
offset', and then computed value is floored to 'min
primary floor activation point' by the driver at run
time. This value is used to avoid setting of switch
point too low accidentally.
Window Multiplier

multipliers in the profile (primary floor activation
window multiplier and primary floor target window
multiplier). This is a static field.

Values for the currently acvive power smoothing preset profile.
**% TMP Floor**
The percentage of the TMP Ceiling, which is used to set
the TMP floor, for the currently active preset profile.
For example, if max TMP is 1000 W, and the % TMP floor
is 50%, then the min TMP value will be 500 W. This value
is in the range [Min % TMP Floor, Max % TMP Floor].

currently active preset profile. This is the power floor
that will be applied during active workload periods on
the GPU when primary floor activation window multiplier
is set to a non-zero value.
Primary Floor Activation Window Multiplier
The time multiplier for the activation moving average
window size for the currently active preset profile.
This is the 'X' ms time multiplier for the activation
moving average window size. The activation moving
average is compared against the (secondary floor +
primary floor activation offset value) to determine if
the controller should switch from the secondary floor to
the primary floor. Setting this to 0 will disable
switching to the secondary floor.
Primary Floor Target Window Multiplier
The time multiplier for the target moving average window
size for the currently active preset profile. This is
the 'X' ms time multiplier for the target moving average
window size. When set to non-zero value, the target
moving average power determines the primary floor. When
set to 0, driver will use the Floor percentage instead
to derive the primary floor.
Primary Floor Activation Offset
The primary Floor Activation Offset, measured in watts,
for the currently active preset profile. If the target
moving average falls below the secondary floor plus this
offset, the primary floor will be activated.
Active Preset Profile Number
The number of the active preset profile.
Admin Overrides

applied during active workload periods on the GPU when
primary floor activation window multiplier is set to a
non-zero value.
Primary Floor Activation Window Multiplier
The admin override value for primary time multiplier for
the activation moving average window size. This is the
'X' ms time multiplier for the activation moving average
window size. The activation moving average is compared
against the (secondary floor + primary floor activation
offset value) to determine if the controller should
switch from the secondary floor to the primary floor.
Setting this to 0 will disable switching to the
secondary floor.
Primary Floor Target Window Multiplier
The admin override value for primary time multiplier for
the target moving average window size. This is the 'X'
ms time multiplier for the target moving average window
size. When set to non-zero value, the target moving
average power determines the primary floor. When set to
0, driver will use the Floor percentage instead to
derive the primary floor.
Primary Floor Activation Offset
The admin override value for primary Floor Activation
Offset, measured in watts. If the target moving average
falls below the secondary floor plus this offset, the
primary floor will be activated.

are in MHz. Note that it is possible for clocks to report a lower
freqency than the lowest frequency that can be set by SW due to HW
optimizations in certain scenarios.

SM Current frequency of SM (Streaming Multiprocessor)
clock.
Memory Current frequency of memory clock.

memory/graphcis clocks. User specified frequency at which applications
will be running at. Can be changed with [-ac \| --applications-clocks]
switches.
Graphics User specified frequency of graphics (shader) clock.

Clock Policy
User-specified settings for automated clocking changes such as auto
boost.
Auto Boost Indicates whether auto boost mode is currently enabled
for this GPU (On) or disabled for this GPU (Off). Shows
(N/A) if boost is not supported. Auto boost allows
dynamic GPU clocking based on power, thermal and
utilization. When auto boost is disabled the GPU will
attempt to maintain clocks at precisely the Current
Application Clocks settings (whenever a CUDA context is
active). With auto boost enabled the GPU will still
attempt to maintain this floor, but will
opportunistically boost to higher clocks when power,
thermal and utilization headroom allow. This setting
persists for the life of the CUDA context for which it
was requested. Apps can request a particular mode either
via an NVML call (see NVML SDK) or by setting the CUDA
environment variable CUDA_AUTO_BOOST. This feature is
deprecated and will be removed in a future CUDA release.
Auto Boost Default
Indicates the default setting for auto boost mode,
either enabled (On) or disabled (Off). Shows (N/A) if
boost is not supported. Apps will run in the default
mode if they have not explicitly requested a particular
mode. Note: Auto Boost settings can only be modified if
"Persistence Mode" is enabled, which is NOT by default.
This feature is deprecated and will be removed in a
future CUDA release.

Device Monitoring
The "nvidia-smi dmon" command-line is used to monitor one or more GPUs
(up to 16 devices) plugged into the system. This tool allows the user
to see one line of monitoring data per monitoring cycle. The output is
in concise format and easy to interpret in interactive mode. The output
data per line is limited by the terminal size. It is supported on
Tesla, GRID, Quadro and limited GeForce products for Kepler or newer
GPUs under bare metal 64 bits Linux. By default, the monitoring data
includes Power Usage, Temperature, SM clocks, Memory clocks and
Utilization values for SM, Memory, Encoder, Decoder, JPEG and OFA. It
can also be configured to report other metrics such as frame buffer
memory usage, bar1 memory usage, power/thermal violations and aggregate
single/double bit ecc errors. If any of the metric is not supported on
the device or any other error in fetching the metric is reported as "-"
in the output data. The user can also configure monitoring frequency
and the number of monitoring iterations for each run. There is also an
option to include date and time at each line. All the supported options
are exclusive and can be used together in any order. Note: On MIG-
enabled GPUs, querying the utilization of encoder, decoder, jpeg, ofa,
gpu, and memory is not currently supported.

Daemon (EXPERIMENTAL)
The "nvidia-smi daemon" starts a background process to monitor one or
more GPUs plugged in to the system. It monitors the requested GPUs
every monitoring cycle and logs the file in compressed format at the
user provided path or the default location at /var/log/nvstats/. The
log file is created with system's date appended to it and of the format
nvstats-YYYYMMDD. The flush operation to the log file is done every
alternate monitoring cycle. Daemon also logs it's own PID at
/var/run/nvsmi.pid. By default, the monitoring data to persist includes
Power Usage, Temperature, SM clocks, Memory clocks and Utilization
values for SM, Memory, Encoder, Decoder, JPEG and OFA. The daemon tools
can also be configured to record other metrics such as frame buffer
memory usage, bar1 memory usage, power/thermal violations and aggregate
single/double bit ecc errors.The default monitoring cycle is set to 10
secs and can be configured via command-line. It is supported on Tesla,
GRID, Quadro and GeForce products for Kepler or newer GPUs under bare
metal 64 bits Linux. The daemon requires root privileges to run, and
only supports running a single instance on the system. All of the
supported options are exclusive and can be used together in any order.
Note: On MIG-enabled GPUs, querying the utilization of encoder,
decoder, jpeg, ofa, gpu, and memory is not currently supported. Usage:
1) Default with no arguments
nvidia-smi daemon
Runs in the background to monitor default metrics for up to 16
supported devices under natural enumeration (starting with GPU index 0)
at a frequency of 10 sec. The date stamped log file is created at
/var/log/nvstats/.
2) Select one or more devices
nvidia-smi daemon -i <device1,device2, .. , deviceN>
Runs in the background to monitor default metrics for the devices
selected by comma separated device list. The tool picks up to 16
supported devices from the list under natural enumeration (starting
with GPU index 0).
3) Select metrics to be monitored
nvidia-smi daemon -s <metric_group>
<metric_group> can be one or more from the following:
p - Power Usage (in Watts) and GPU/Memory Temperature (in C) if
supported
u - Utilization (SM, Memory, Encoder, Decoder, JPEG and OFA Utilization
in %)
c - Proc and Mem Clocks (in MHz)
v - Power Violations (in %) and Thermal Violations (as a boolean flag)

5) Configure log directory
nvidia-smi daemon -p <path of directory>
The log files are created at the specified directory.
6) Configure log file name
nvidia-smi daemon -j <string to append log file name>
The command-line is used to append the log file name with the user
provided string.
7) Terminate the daemon
nvidia-smi daemon -t
This command-line uses the stored PID (at /var/run/nvsmi.pid) to
terminate the daemon. It makes the best effort to stop the daemon and
offers no guarantees for it's termination. In case the daemon is not
terminated, then the user can manually terminate by sending kill signal
to the daemon. Performing a GPU reset operation (via nvidia-smi)
requires all GPU processes to be exited, including the daemon. Users
who have the daemon open will see an error to the effect that the GPU
is busy.
8) Help Information
nvidia-smi daemon -h
Displays help information for using the command line.
Replay Mode (EXPERIMENTAL)
The "nvidia-smi replay" command-line is used to extract/replay all or
parts of log file generated by the daemon. By default, the tool tries
to pull the metrics such as Power Usage, Temperature, SM clocks, Memory
clocks and Utilization values for SM, Memory, Encoder, Decoder, JPEG
and OFA. The replay tool can also fetch other metrics such as frame
buffer memory usage, bar1 memory usage, power/thermal violations and
aggregate single/double bit ecc errors. There is an option to select a
set of metrics to replay, If any of the requested metric is not
maintained or logged as not-supported then it's shown as "-" in the
output. The format of data produced by this mode is such that the user
is running the device monitoring utility interactively. The command
line requires mandatory option "-f" to specify complete path of the log
filename, all the other supported options are exclusive and can be used
together in any order. Note: On MIG-enabled GPUs, querying the
utilization of encoder, decoder, jpeg, ofa, gpu, and memory is not
currently supported. Usage:
1) Specify log file to be replayed
nvidia-smi replay -f <log file name>
Fetches monitoring data from the compressed log file and allows the
user to see one line of monitoring data (default metrics with time-
stamp) for each monitoring iteration stored in the log file. A new line
of monitoring data is replayed every other second irrespective of the
actual monitoring frequency maintained at the time of collection. It is
displayed till the end of file or until terminated by ^C.
2) Filter metrics to be replayed
nvidia-smi replay -f <path to log file> -s <metric_group>
<metric_group> can be one or more from the following:

3) Limit replay to one or more devices
nvidia-smi replay -f <log file> -i <device1,device2, .. , deviceN>
Limits reporting of the metrics to the set of devices selected by comma
separated device list. The tool skips any of the devices not maintained
in the log file.
4) Restrict the time frame between which data is reported
nvidia-smi replay -f <log file> -b <start time in HH:MM:SS format> -e
<end time in HH:MM:SS format>
This option allows the data to be limited between the specified time
range. Specifying time as 0 with -b or -e option implies start or end
file respectively.
5) Redirect replay information to a log file
nvidia-smi replay -f <log file> -r <output file name>
This option takes log file as an input and extracts the information
related to default metrics in the specified output file.
6) Help Information
nvidia-smi replay -h
Displays help information for using the command line.
Process Monitoring
The "nvidia-smi pmon" command-line is used to monitor compute and
graphics processes running on one or more GPUs (up to 16 devices)
plugged into the system. This tool allows the user to see the
statistics for all the running processes on each device at every
monitoring cycle. The output is in concise format and easy to interpret
in interactive mode. The output data per line is limited by the
terminal size. It is supported on Tesla, GRID, Quadro and limited
GeForce products for Kepler or newer GPUs under bare metal 64 bits
Linux. By default, the monitoring data for each process includes the
pid, command name and average utilization values for SM, Memory,
Encoder and Decoder since the last monitoring cycle. It can also be
configured to report frame buffer memory usage for each process. If
there is no process running for the device, then all the metrics are
reported as "-" for the device. If any of the metric is not supported
on the device or any other error in fetching the metric is also
reported as "-" in the output data. The user can also configure
monitoring frequency and the number of monitoring iterations for each
run. There is also an option to include date and time at each line. All
the supported options are exclusive and can be used together in any

DEPRECATON AND REMOVAL NOTICES
Features deprecated and/or removed between nvidia-smi v580 Update and v575

CHANGE LOG
Known Issues
• On systems where GPUs are NUMA nodes, the accuracy of FB memory
utilization provided by nvidia-smi depends on the memory accounting
of the operating system. This is because FB memory is managed by the
operating system instead of the NVIDIA GPU driver. Typically, pages
allocated from FB memory are not released even after the process
terminates to enhance performance. In scenarios where the operating
system is under memory pressure, it may resort to utilizing FB
memory. Such actions can result in discrepancies in the accuracy of
memory reporting.
• On Linux GPU Reset can't be triggered when there is pending GOM
change.
• On Linux GPU Reset may not successfully change pending ECC mode. A
full reboot may be required to enable the mode change.
• On Linux platforms that configure NVIDIA GPUs as NUMA nodes, enabling
persistence mode or resetting GPUs may print 'Warning: persistence
mode is disabled on device' if nvidia-persistenced is not running, or
if nvidia-persistenced cannot access files in the NVIDIA driver's
procfs directory for the device (/proc/driver/nvidia/gpus/<PCI
config='' address>=''>/). During GPU reset and driver reload, this
directory will be deleted and recreated, and outstanding references
to the deleted directory, such as mounts or shells, can prevent
processes from accessing files in the new directory.
• There might be a slight discrepency between volatile/aggregate ECC
counters if recovery action was not taken
• The GPU hostname commands are currently only supported on compatible
GB200 platforms.
