SHMEM_INT_INC(3) | Open MPI | SHMEM_INT_INC(3) |
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:
NOTES¶
The term remotely accessible is defined in intro_shmem(3).
RETURN VALUES¶
