Another site had a paper. Have anyone come across Linpack paper?
The site is http://www.csis.hku.hk/~clwang/gideon300/peak.html.
I had the same problem interpret the results when I ran test supplied my
mpich, eg mpptest and gotest.
Will it be worth setting up a performance chart for small clusters. It can
include, FLOPS, Network performance etc.
