I suspect some limitation in the configuration on your cluster. (for
example, what is OpenFabrics and what does it have to do with MPI?)  You
may need to speak with your cluster administrators.

I've successfully used foreach and doMPI on over 250 worker nodes.

Unfortunately, I'm not sure how much additional help I can be beyond my
one data point, as I no longer have access to that particular cluster.
