whats the question??
the effeciency we saw improved with increased memory, also improves
with more cores on a node...

Can you post a reference to the list for Jim Pepin's ppt ?
Google didn't come up with anything useful
Closest might be "Building and Benchmarking a 10 TF Linux Cluster"
Jim Pepin,
USC at Sun HPC consortium 2005 but can't find any online resources
for this ?

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.
Eric
