[Beowulf] I/O bound simulation

I have been reading the list for quite a while and have
gleaned a boat load of information.
Now I am going to ask help for a problem I am having.
I have simulation program that runs on between 5 and 15
nodes. This depends on the desired fidelity of the simulation.
When I approach the higher fidelity levels, the simulation starts
to choke on the quantity of data being processed.
It appears that the system is failing on I/O. Transferring large
amounts of time critical data between process elements.
I a running on a mostly standard Red Hat distro, no special
compiling or running architectures are in place.
Do any of you have suggestions as to how I might start
getting control of this I/O problem?
Thanks for any help.
