SHMEM_FETCH(3) Open MPI SHMEM_FETCH(3)
NAME
shmem_int4_fetch(3), shmem_int8_fetch(3), shmem_int_fetch(3),
shmem_long_fetch(3), shmem_longlong_fetch(3) shmem_double_fetch(3)
shmem_float_fetch(3) - Atomically fetches the value of a remote data
object
SYNOPSIS
C or C++:
#include <mpp/shmem.h>
int shmem_int_fetch(int *target, int pe);
long shmem_long_fetch(long *target, int pe);
long long shmem_longlong_fetch(long long *target, int pe);
double shmem_double_fetch(long long *target, int pe);
float shmem_float_fetch(float *target, int pe);
Fortran:
INCLUDE "mpp/shmem.fh"
INTEGER pe
INTEGER(KIND=4) SHMEM_INT4_FETCH, ires, target
ires = SHMEM_INT4_FETCH(target, pe)
INTEGER(KIND=8) SHMEM_INT8_FETCH, ires, target
ires = SHMEM_INT8_FETCH(target, pe)
REAL(KIND=4) SHMEM_INT4_FETCH, ires, target
ires = SHMEM_REAL4_FETCH(target, pe)
REAL(KIND=8) SHMEM_INT8_FETCH, ires, target
ires = SHMEM_REAL8_FETCH(target, pe)
DESCRIPTION
The shmem_fetch functions perform an atomic fetch operation. They re-
turn the contents of the target as an atomic operation.
The arguments are as follows:
target The remotely accessible data object to be fetched from the re-
mote PE.
pe An integer that indicates the PE number from which target is to
be fetched. If you are using Fortran, it must be a default inte-
ger value.
RETURN VALUES
The contents at the target address on the remote PE. The data type of
the return value is the same as the the type of the remote data object.
