While I was reading benchmarkreviews.com I discovered that they use Folding in their full load testing.

"After the results have been recorded from the light idle load, our test system then receives heavy load by utilizing ATITool to scan for artifacts and two Folding@home console clients. ATITool forces the video card into high-power 3D mode, and the Folding@home clients cause 100% CPU utilization on each core. After many months of research, these two programs have proven to create more power draw than anything else available, including the combined EVEREST System Stability Test."

We've always contended that PC overclockers needed to use Gromacs (or StressCPU2, which is the same thing) to test their stability. It's nice that the GPU community has discovered the same thing. (And probably why Microsoft doesn't want people to talk about FAH on the Xbox).

Kudos to the Pande Group and to Gromacs.org for creating the most efficient code ever produced that gets the most work out of whatever hardware you've got.

Gromacs was added to the professional benchmarking tools used by system builders recently, i.e. Spec2006.

As this topic is pretty close what I have in mind I'll post my question in here.

I was wondering does the F@H -client verify correctness of its computations in anyway? I'm running folding on overclocked PC and although I have done gazillion different overclocking stress tests I'm still wondering what happens if my CPU isn't stable. For example programs like Prime95 can spot a miss behaving CPU quite well. Does F@H have the same capability? I do not want to provide wrong kind of data to the system. And I personally have 0-tolerance towards errors in overclocking, even if it happens after running the client successfully for 14 days straight and after that it errors out.

FAH will detect if a computing error make the WU enter in an abnormal state ... it's what we call an Early Unit End.

If you want to stress your CPU with something very similiar to FAH, you can use the Gromacs StressCPU http://www.gromacs.org/component/option ... Itemid,26/ : this program is intended for testing and always verify the operations he's doing.
