SHMEM_INC(3) Open MPI SHMEM_INC(3)
NAME
shmem_int4_inc(3), shmem_int8_inc(3), shmem_int_inc(3),
shmem_long_inc(3), shmem_longlong_inc(3) - These routines perform an
atomic increment operation on a remote data object.
SYNOPSIS
C or C++:
#include <mpp/shmem.h>
int shmem_int_inc(int *target, int pe);
long shmem_long_inc(long *target, int pe);
long long shmem_longlong_inc(long long *target, int pe);
Fortran:
INCLUDE "mpp/shmem.fh"
INTEGER pe
INTEGER(KIND=4) SHMEM_INT4_INC, target4
INTEGER(KIND=8) SHMEM_INT8_INC, target8
ires4 = SHMEM_INT4_INC(target4, pe)
ires8 = SHMEM_INT8_INC(target8, pe)
DESCRIPTION
The atomic increment routines replace the value of target with its
value incremented 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:
target 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.
pe An integer that indicates the PE number upon which target is to
be updated. If you are using Fortran, it must be a default inte-
ger value.
NOTES
The term remotely accessible is defined in intro_shmem(3).
RETURN VALUES
None.
