Almost two years have passed since Stanford University kicked off its Folding@home GPU project. The initiative took Stanford's distributed computing project to ATI's Radeon graphics cards, yielding considerable performance gains with some types of workloads.
This morning, Folding@home Director Vijay Pande announced the start of an open beta testing campaign for the next-generation GPU client, which is nicknamed FAH GPU2. According to Pande, the Folding@home team have carried out a limited alpha and a bigger, closed beta test for the new client, and they think GPU2 is now mature enough for public testing. Pande points out that the software still isn't flawless, that it could be unstable, and that points benchmarking "may change due to software or policy changes." However, he says there ought to be no show-stopping bugs.
The GPU2 folding client can be downloaded directly from this link. The client supports AMD's Radeon HD 2000- and Radeon HD 3000-series graphics processors running under either Windows XP Service Pack 2 or Windows Vista in 32-bit or 64-bit flavors. A list of frequently asked questions pertaining to the new client can be perused here.
As always, if you want to take up folding (or just test the GPU2 client), feel free to join team #2630 to do your part in helping cure diseases like cancer and Alzheimer's while advancing TR on the Folding@home team rankings page.
