Also, check out the changes that Jim Pepin at USC made to his cluster to
produce more teraflops. There is a Powerpoint on the web that gives some
of the details. If I remember correctly he actually removed RAM from the
nodes and made a few other changes.

Hi,
There is a rank 367 which achieve 79.97% efficiency.
i'm using Infiniband to connect 2 nodes. each node has 8G memory and dual AMD
opteron 250.
i just tried Intel Compiler + GOTO, it just got a 60% efficiency which have a
large difference with my target.
maybe i need to try Pathscale or PGI compiler.
any suggestion?
thanks a lot.
Start with single node runs, then work you way up from there.
