mpi.recv or mpi.irecv needs a buffer to store an incoming messenger and
must know in advance the size of the buffer. For mpi.irecv.Robj to work,
one needs to probe the incoming messenger size which is a block call. So
there is no point to implment mpi.irecv.Robj unless there is an another
nonbl
Hi Dirk,
Thank for pointing out additional flags needed in order to compile Rmpi
correctly. Those flags can be added in configure.ac once openmpi dir is
detected. BTW -DMPI2 flag was missed in your Rmpi since the detection of
openmpi was not good. It should be
if test -d ${MPI_ROOT}/
if r-project
will put lam into OS X and make Rmpi officially available to Mac. I need
to fully test Rmpi before submitting next version.
Thanks all and have nice weekend days.

Because of the change, all character messengers fail. Is there an easy way
to get a char pointer to STRING_ELT((sexp_rdata),0) and is also backward
compatible to old R versions. BTW Rmpi does not do any modification of
characters at C level.
Thanks
