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.
mpi.isend.Robj
is a nonblocking version of mpi.send.Robj
.
Usage
mpi.send.Robj(obj, dest, tag, comm = 1)
mpi.isend.Robj(obj, dest, tag, comm = 1, request=0)
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. |
request |
a request number. |
status |
a status number. |
Details
mpi.send.Robj
and mpi.isend.Robj
use
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
.
If mpi.isend.Robj
is used, mpi.wait
or mpi.test
must
be used to check the object has been sent.
Value
mpi.send.Robj
or mpi.isend.Robj
return no value.
mpi.recv.Robj
returns the the transmitted R object.
