Rmpi over mpich2 working, new questions

We worked through our problems and got Rmpi to work on Red Hat, even  
calling it from
papply. Thanks for your help.

Interestingly, a  parallelization of 1,000 trivial operations involving
7 slaves took  32 seconds on our system. Is it possible that the
message passing overhead is borne in serial and takes 32
milliseconds per task?


Thanks again,

Tom
