Yes, I think you are right, but we are going to use OpenMPI and we wanted
to hear and your opinion (OpenMPI experts opinion) :)

At this moment we use MPI and PVM but we would like to test and use other
technologies, projects, ideas as well. I think that SGE GridEngine is a
very good project and maybe that is our final choise!

Yes, at this time we think to use an additional node as the master node
with a better HDD for these jobs
