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.
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)
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 integer value.
The term remotely
accessible is defined in intro_shmem(3).
None.
