PROJECTS 7620 and 7621 - CheY Folding

Moving to advanced!

For nVidia Fermi GPUs (GPU3) on Win32 machines
Points = 5187
timeout = 12.6
deadline = 17.9
atoms = 1980

Additionally, these WUs will require a new version (v2.20) of Core15, which should be automatically downloaded as needed.

These projects aim to study the folding of CheY, which, if successful, will be the largest protein folded in silico. CheY is well-studied experimentally, and exhibits many interesting scientific features. Due to it's wide study in the lab, we hope that it will provide a test case for FAH methodology, and give us good ideas about how to improve our techniques. This is an exciting project, since it represents something that is really only possible on FAH combined with the power of GPUs.

NOTE: These WUs are significantly larger than previously released GPU WUs. While I stress *we have not seen any damaged hardware*, they may stress older cards (GTX 450 and earlier) and overclocked cards. If you have an overclocked card, and receive one of these units, monitor your card's temperature actively. You may want to reset to factory clock settings.

Beware that if you are overclocking you may run into issues running these WUs as some donors have.

As many have stated, turning down the clock speed should solve the issue.

Update on these units:

For the time being, these units will remain on Advanced - that is, you will only receive them if running a client with the advanced methods flag. This should ensure that donors can choose whether or not to opt-in to receive these units. If curious, I would encourage donors to give these units a shot and give us feedback on how they go!

To accelerate these projects, we will be slowly moving other projects running on GPU3 (Fermi)/advanced methods to full FAH.

Eventually, our plan is to release these units to the full FAH community, but right now we want to give donors the choice to opt-in or out.
