Returns the number of processing elements (PEs) running in the job.
#include <shmem.h> int num_pes(void);
The num_pes function returns the number of PEs running in an application.
For current implementation, this value is equal to the MP_PROCS environment variable.
#include <shmem.h>
#include <stdio.h>

printf("FAILED\n");
return 0;
} else {

}

if (my_task < 0){
printf("FAILED\n");
return 0;
} else {
printf("my pe id is %d\n", my_task);
