num_pes(3I)

NAME
     _num_pes, NUM_PES - Returns the number of processing elements (PEs)
     running in an application

SYNOPSIS
     C or C++:

     #include <intrinsics.h>
     int _num_pes (void);

     Fortran:

     I = NUM_PES()

IMPLEMENTATION
     C/C++:  UNICOS and UNICOS/mk

     Fortran:  UNICOS, UNICOS/mk, and IRIX systems

     Cray C/C++, CF90, MIPSpro 7 Fortran 90

STANDARDS
     C/C++ extension

     Fortran extension

DESCRIPTION
     The num_pes function returns the number of PEs running in an
     application.

C/C++ NOTES
     The _num_pes intrinsic function is evaluated at run-time and cannot be
     used in constant expressions.

     Because _num_pes is an intrinsic function, no externally visible
     library function is available for it.  The compiler generates inline
     code to produce the result.

     UNICOS/mk systems is in the Cray C/C++ Reference Manual.
