mpi.any.source: MPI Constants

Description

Find MPI constants: MPI\_ANY\_SOURCE, MPI\_ANY\_TAG, or MPI\_PROC\_NULL

Usage

mpi.any.source()
mpi.any.tag()
mpi.proc.null()

Value

Each function returns an integer value.

Details

These constants are mainly used by mpi.send, mpi.recv, and mpi.probe. Different implementation of MPI may use different integers for MPI\_ANY\_SOURCE, MPI\_ANY\_TAG, and MPI\_PROC\_NULL. Hence one should use these functions instead real integers for MPI communications.
