R: Extensions of MPI_Send and MPI

mpi.send.Robj {Rmpi}

R Documentation

Extensions of MPI_Send and MPI_Recv APIs

Description

mpi.send.Robj and mpi.recv.Robj are two extensions of mpi.send and mpi.recv. They are used to transmit a general R object from any source to any destination.

Usage

mpi.send.Robj(obj, dest, tag, comm = 1)
mpi.recv.Robj(source, tag, comm = 1, status = 0)

Arguments

`obj`	an R object. Can be any R object.
`dest`	the destination rank.
`source`	the source rank or mpi.any.source() for any source.
`tag`	non-negative integer or mpi.any.tag() for any tag.
`comm`	a communicator number.
`status`	a status number.

Details

mpi.send.Robj uses serialize to encode an R object into a binary char vector. It sends the message to the destination. The receiver decode the message back into an R object by using unserialize.

Value

mpi.send.Robj returns no value. mpi.recv.Robj returns the the transmitted R object.
