Load Tests for Distributed Systems? 14
arizaphale asks: "I stand in front of the somewhat complex task of load testing a fairly simple distributed telecom computer system. Is there anyone who has links or references to where I can find information about some theory on which I can base my tests? Both formal theories and test methodology are of great interest to me."

Test TPC-C TPC-H TPC-R and TPC-W
You will find a description of all of them here http://www.tpc.org/information/benchmarks.asp [tpc.org] and each have their own pdf description. VERY FORMAL and detailed. Have Fun ])

If you want to crunch a few ones and zeroes, look at the following book: Designing and Building Parallel Programs [anl.gov] (it is free!). If you pick a nice algo here you can probably test some bandwidth too.
As a side note: he doesn't need a Beowolf cluster of these, he allready has a distributed computer system!

Make sure to save lots of data so you can make some conclusions. Write the report (and post URL on slashdot).

Let a simulator use the log to generate the traffic in your test setup.
