sigh.

Linpack is ubiquitous - just look for 'xhpl' in Google.
It will take you to http://www.netlib.org/benchmark/hpl/
Unfortunately this benchmark does not test all aspects of a high performance cluster. Most notably it doesn't really stress MPI, such that most high performance interconnect solutions (IBA, Myrinet, Quadrics et al. [*])  would give fairly similar performance figures.


Yours,

ps. [*] yes I do work for one of those vendors
