SHMEM_MY_PE(3) Open MPI SHMEM_MY_PE(3)

shmem_my_pe, my_pe, _my_pe - Returns the virtual PE number of the calling PE.

C or C++:

#include <mpp/shmem.h>
int shmem_my_pe (void);
int my_pe (void);

Fortran:

include 'mpp/shmem.fh'
I = SHMEM_MY_PE ()
I = MY_PE ()

my_pe() or shmem_my_pe() return the processing element (PE) number of the calling PE. It accepts no arguments. The result is an integer between 0 and npes - 1, where npes is the total number of PEs executing the current program.
