MPIL_Universe_size - LAM/MPI-specific function to obtain
the number of nodes in the MPI environment
SYNOPSIS
#include <mpi.h>
int MPIL_Universe_size(int *size)
OUTPUT PARAMETER
size - number of nodes in the MPI environment (from lam
boot )
NOTES
This function is deprecated. It has been replaced with an
MPI-2 attribute on MPI_COMM_WORLD - MPI_UNIVERSE_SIZE ,
which provides the same functionality. This function is
(or effectively is) a wrapper to the replacement
attribute, anyway. User programs should use the MPI-2
replacement attribute instead of this function.
Some functions are deprecated because their names did not
conform to the stricter naming conventions of MPI-2; oth
ers are deprecated because they have been replaced with
more flexible functionality.
