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 return the contents of the target as an atomic operation.
The arguments are as follows:
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.
