mpi.const

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()

Arguments

None

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.

Value

Each function returns an integer value.
