We have ordered the cluster from a local builder, and expect delivery in about 4 weeks. I am a servant of the Oceanographers, my specialty is software. Thanks for the advice. I conclude there are no magic bullet solutions. One must do research, make an educated guess, and then hold one's nose and jump in at the deep end. There is one question that perplexes me, to which I have not found an answer. How does the presence of a job scheduler interact with the ability of a user to ssh to <head>, ssh to <compute-node-n>, and then type mpirun -np 64 my_application Intuition tells me there has to be something in a cluster setup, when it has a scheduler, that prevents a user from circumventing the scheduler by doing something like the above. Any hints? > John Hearns McLaren Racing BTW, congratulations on a great season this year.
