mpi.const: MPI Constants

In Rmpi: Interface (Wrapper) to MPI (Message-Passing Interface)

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.
