SYNOPSIS

Fortran extension

DESCRIPTION

The C _num_pes and the Fortran NUM_PES functions return the number of processing elements (PEs) running in an application.

NOTES

The _num_pes and NUM_PES intrinsic functions are evaluated at run time and cannot be used in constant expressions.

Because _num_pes and NUM_PES are intrinsic functions, no externally visible library functions are available for them. The compiler generates inline code to produce the result.
