See the link in my sig, there's the new Folding Benchmark CD that I promised about 2 months ago - sorry it took so long.
Here's how it works:
The CD boots up and downloads both the folding client program plus the cores required all directly from Stanford (as required by their license) so the internet connection speed will not affect the result.
It then starts folding a WU per processor until it folds 1 complete step
It then takes the measurement for that WU, stops that one and starts the next.
If there are multiple processors it will leave the last WU running to provide load on the processors until all are complete and then shut them all down.
It benchmarks 4 WU types - Tinker, Amber, Gromacs and Gromacs3.3.
Results are available on the screen and on a web page, just point your browser at the machine being benchmarked. The URL is published on the screen as the machine starts up so you can tell what it is. Individual results are produced for each WU, average results are calculated across the 4 WU types and a total is calculated by multiplying the average by the number of processors.
Enjoy, but please don't meltdown my server
FYI this uses GPL code so if you want to mirror it you also must mirror the source file as well as the .iso. Other than that, you don't need the source file and it's so big that you really don't want to try downloading it from my poor server.
This uses a lot of new stuff that I am going to now work into the Folding CD generator / Diskless HOWTO / Folding USB stick and that should fix the problem with core 82 that has been reported recently.
