Sure! I'm running 382 hyperthreaded CPUs on an MPI cluster with no
problem as I'm typing now. I just use the following lines:

     cpus <- 382                # Number of CPUs to cluster together
     sfSetMaxCPUs(cpus)            # Use when plan more than 32 CPUs
     sfInit(parallel=T, cpus=cpus, slaveOutfile="initfile", type="MPI")
# Initialize MPI cluster
     stopifnot(sfCpus()==cpus)        # Confirm set up CPUs properly
     stopifnot(sfParallel()==TRUE)    # Confirm now running in parallel

Cheers,
Phil
