Probe Functions

Description

The functions call MPI probe functions.

Usage

probe(rank.source = .pbd_env$SPMD.CT$rank.source,
      tag = .pbd_env$SPMD.CT$tag, comm = .pbd_env$SPMD.CT$comm,
      status = .pbd_env$SPMD.CT$status)
iprobe(rank.source = .pbd_env$SPMD.CT$rank.source,
       tag = .pbd_env$SPMD.CT$tag, comm = .pbd_env$SPMD.CT$comm,
       status = .pbd_env$SPMD.CT$status)

Arguments

rank.source

a source rank where an object sent from.

tag

a tag number.

comm

a communicator number.

status

a status number.
