Cluster Benchmarks

there is the NAS PB benchmarking suite. I've used this one a bit, and it 
seems well written, however, the reporting looks skewed. For example, on a 
4-node dual processor 1.2 GHz Athlon MP cluster, we were getting numbers like 
300 - 500 _M_flops, whereas linpack was reporting 6 - 8 Gflops, a more 
reasonable number. (I can't remember the exact numbers.) It may be that the 
NAS code is just old. Tuning didn't help much either. I'd be interested to 
know if anyone else has had similar experiences with this benchmark.
