HPL, as someone else mentioned is nice. Total flops are nice, but
Rmax/Rpeak is something i always look at, to see what percentage of the

Pallas PMB - http://www.pallas.com/e/products/pmb/index.htm
To be honest, i've never really used this as a 'benchmark', but include it
in tests to validate a clusters operation.
