dd_prob: Probe Functions

In pbdMPI: R Interface to MPI for HPC Clusters (Programming with Big Data Project)

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.

Details

These functions are for internal functions. Potentially, they set/get probe for receiving data.

Value

An invisible state of MPI call is returned.
