MPIL_Universe_size(3) LAM/MPI MPIL_Universe_size(3)
MPIL_Universe_size - LAM/MPI-specific function to obtain the number of nodes in the MPI environment
int MPIL_Universe_size(int *size)
size - number of nodes in the MPI environment (from lamboot )
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; others are deprecated
because they have been replaced with more flexible functionality.
