SHMEM_CHAR_P(3) Open MPI SHMEM_CHAR_P(3)
NAME
shmem_char_p(3), shmem_float_p(3), shmem_int_p(3), shmem_long_p(3),
shmem_short_p(3), shmem_longlong_p(3), shmem_longdouble_p(3) - These
routines provide a low latency mechanism to write basic types (char,
short, int, float, double, long, long long, long double) to symmetric
data objects on remote PEs.
SYNOPSIS
C or C++:
#include <mpp/shmem.h>
void shmem_char_p(char *addr, char value, int pe);
void shmem_short_p(short *addr, short value, int pe);
void shmem_int_p(int *addr, int value, int pe);
void shmem_long_p(long *addr, long value, int pe);
void shmem_longlong_p(long long *addr, long long value, int pe);
void shmem_float_p(float *addr, float value, int pe);
void shmem_double_p(double *addr, double value, int pe);
void shmem_longdouble_p(long double *addr, long double value, int pe);
DESCRIPTION
These routines provide a very low latency put capability for single el-
ements of most basic types.
The arguments are as follows:
addr The remotely accessible array element or scalar data object
which will receive the data on the remote PE.
value The value to be transferred to addr on the remote PE.
pe The number of the remote PE.
As with shmem_put(3), these functions start the remote transfer and may
return before the data is delivered to the remote PE. Use
shmem_quiet(3) to force completion of all remote PUT transfers.
