NAME

     available_threads - returns information about current thread
     usage

SYNOPSIS

     SUBROUTINE AVAILABLE_THREADS(NTOTAL, NUSING)

     INTEGER NTOTAL, NUSING

     SUBROUTINE AVAILABLE_THREADS_64(NTOTAL, NUSING)

     INTEGER*8 NTOTAL, NUSING

  F95 INTERFACE
     SUBROUTINE AVAILABLE_THREADS(NTOTAL, NUSING)

     INTEGER :: NTOTAL, NUSING

     SUBROUTINE AVAILABLE_THREADS_64(NTOTAL, NUSING)

     INTEGER(8) :: NTOTAL, NUSING

  C INTERFACE
     #include <sunperf.h>

     void available_threads(int *ntotal, int *nusing);

     void available_threads_64(long *ntotal, long *nusing);

PURPOSE

     available_threads threads returns NTOTAL, which is the total
     number of CPUs available to the job (generally the number of
     CPUs presently on-line in the partition), and NUSING,  which
     is the sum of the current Use numbers for all threads speci-
     fied in USE_THREADS.  If NTOTAL < NUSING then the system  is
     potentially overcommitted.

ARGUMENTS

     NTOTAL (output)
               Total number of CPUs available.

     NUSING (output)
               Sum of current Use numbers for all threads  speci-
               fied in USE_THREADS.
