Benchmark page on wiki

[oliver]

I started a simple Hippo Benchmark page on the wiki.

Basically, just run under Linux

Code: Select all

cd testjobs
time ./calc_testjobs

and report the user time and the cpu.

(Completely un-scientific but probably better than nothing and gives a first indication of relative performance of architectures.)

I added scaling benchmarks to the wiki page.

I simply ran the WALP + octane MD simulation, took the time and plotted the results. The general results (for this system) appear to be that performance gains beyond 4 cores are negligible.

Tentative conclusions:

• It does not matter if you use the hippo or hippo_p3 binary (at least for the revisions tested).
• The MD code only scales up to ~4 cores (with a factor of about 3.3) (tested on the WALP+octane MD test case).
• Fast Intel processors are good.
