Hi Gus, > How do you intend to use Rmpi? The problem I want to solve/attack is in highly embarrasingly parallel nature. According to a couple of brief tutorials I read, Rmpi favors LamMpi and, as I understand, even with emergence of openMPI it hasn't been modified in the way to work with

Hi Siegmar, Many thanks for your reply. I have tried man pages you mention, but one hurdle I am running into is orte_hosts page. I don't find the specification of fields for the file. I see an example: dummy1 slots=4 dummy2 slots=4 dummy3 slots=4 dummy4 slots=4 dummy5 slots=4
