NAME

       shmem_int4_fetch(3),         shmem_int8_fetch(3),         shmem_int_fetch(3),        shmem_long_fetch(3),
       shmem_longlong_fetch(3) shmem_double_fetch(3) shmem_float_fetch(3) - Atomically fetches the  value  of  a
       remote data object

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:

       target The remotely accessible data object to be fetched from the remote PE.

       pe     An integer that indicates the PE number from which target is to  be  fetched.  If  you  are  using
              Fortran, it must be a default integer value.

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.
