Great. Considerations some other centers have had can be found at:

Thanks for the list. Most of them I've already come across in my
search, but the AMD HPC guide is one I haven't come across before that
will definitely be handy.

Hi Prentice,
If all you want to compare is the performance of one CPU, then you
could use the SPEC benchmarks, SPECint and SPECfp. Both are
available for many CPUs at spec.org <http://spec.org>. Source is
unfortunately only accessible for SPEC members.
Best, Jan

Beowulfers,
Do any of you have any experience using HPCG as a benchmark. I'm
trying to compare the performance of several different processors
for an upcoming purchase. I've already run LINPACK, and now I'd
like to run HPCG. It seems the only tuning parameter is the size of
the local grid in the x,y,z dimensions.
While the guidelines say to increase the gridsize until the job
consumes 1/4 or more of RAM, my testing has shown that as the
gridsize goes up, so does the performance, and it keeps going up
for me until I consume all the memory and the job gets killed by
Slurm for exceeding memory requirements.
I've been doing a lot of Google searching for how to tune HPCG for
maximum results, and there are some papers for tuning HPCG for
large supercomputers. In these cases, they use x,y,z dimensions
that are not necessarily equal, but I don't understand how they
determined to use these unique values for x,y,z.
When I compare my HPL results to my HPCG results, I'm getting HPCG
results that are 0.3 - 0.5% of HPL. On the HPCG Top500 list, most
systems are getting 2-3% of HPL, so I'm off by an order of magnitude.
