SHMEM_FETCH(3)

okay bestie, welcome to SHMEM_FETCH(3) from Open MPI 💖 this page is all about the fetch girlies and they are lowkey iconic.

💖 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) — these besties atomically fetch the value of a remote data object. periodt. 💅

✨ 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)

copy those exactly, bestie — character for character, no “fixing” the iconic quirks. 🎀

🦋 DESCRIPTION 🦋

The shmem_fetch functions perform an atomic fetch operation. They return the contents of the target as an atomic operation. no cap, that’s the whole vibe. ✨

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 type of the remote data object. 💫
