Hi Peter,
I'm looking at MPI examples, thank you for the advice.
But If It's possible to use several instances with MPI. I think It should be
possible with OpenMP.
Thank you

Hi David,
It's my understanding is that the RInside class is a singleton as R is strictly
single threaded. The message you are seeing if an exception thrown because the
singleton constraint is violated.
There are some examples that ship with RInside which demonstrate the use of
multiple RInside processes using MPI. They might help you achieve the
parallelism you are wanting.
Correct me if I'm wrong, Dirk.
Thanks
Peter
