C or C++:
#include <mpp/shmem.h> int shmem_int_finc(int *target, int pe) long shmem_long_finc(long *target, int pe) long long shmem_longlong_finc(long long *target, int pe)
INCLUDE "mpp/shmem.fh" INTEGER pe INTEGER(KIND=4) SHMEM_INT4_FINC, target4 INTEGER(KIND=8) SHMEM_INT8_FINC, target8 ires4 = SHMEM_INT4_FINC(target4, pe) ires8 = SHMEM_INT8_FINC(target8, pe)
The fetch and increment routines retrieve the value at address target on PE pe, and update target with the result of incrementing the retrieved value by one. The operation must be completed without the possibility of another process updating target between the time of the fetch and the update.
The arguments are as follows:
The remotely accessible integer data object to be updated on the remote PE. The type of target should match that implied in the SYNOPSIS section.
An integer that indicates the PE number upon which target is to be updated. If you are using Fortran, it must be a default integer value.
The term remotely accessible is defined in intro_shmem(3).
184.108.40.206. RETURN VALUES
The contents that had been at the target address on the remote PE prior to the increment.
