PMI_Get_numpes_on_smp

PMI_Get_numpes_on_smp - Returns the number of processes in the local process group that are on the local node along with the local process

SYNOPSIS

C or C++ SYNOPSIS

#include <pmi.h>
int PMI_Get_numpes_on_smp(int *size);

IMPLEMENTATION

Cray Linux Environment (CLE)

DESCRIPTION

Returns the number of processes in the local process group that are on the local node along with the local process. This is a simple topology function to distinguish between processes that can communicate through IPC mechanisms (e.g., shared memory) and other network mechanisms. It behaves similarly to PMI_Get_numpes_in_app_on_smp() but does not limit itself to those ranks participating in the local application. This function replaces the deprecated PMI_Get_clique_size() function.

size

Pointer to an integer that receives the size of the clique.

RETURN VALUES

PMI_SUCCESS

Operation completed successfully

PMI_FAIL

Operation failed

PMI_ERR_INIT

PMI not initialized

PMI_ERR_INVALID_ARG

Invalid argument
