I'm developing a model in C, and I need to run a couple of simulations (lengthy, and heavy ones). I seem to have a cluster at my disposal, but I'm not very familiar with the concept. I understand that there are different "nodes" ? My program is not designed to take advantage of this individually - it can't event take advantage of multiple processors, because the calculations have to be done in sequence. But I have to run multiple instances of the program, and I was hoping there'd be a way to run them on separate "nodes" (?) to avoid them having to share CPU time too much.
What I know : the cluster runs Red Hat Enterprise Linux for Servers 5.3.
Can anyone help?
