Hi,

I agree that real performance of beowulf depends on your application.
Anyway, if you need to get some ideas about system performance . People
usually run slbench ,
parallel benchmark from UTK. Please obtain it by going to ATLAS project.
Net pipe and net perf seems to be a standard for testing network
performance.
All these benchmark and more can be found at.
