Folding@home is a distributed computing project — people from throughout the world download and run software to band together to make one of the largest supercomputers in the world. Every computer takes the project closer to our goals. Folding@home uses novel computational methods coupled to distributed computing, to simulate problems millions of times more challenging than previously achieved. Moreover, when proteins do not fold correctly (i.e. “misfold”), there can be serious consequences, including many well known diseases, such as Alzheimer’s, Mad Cow (BSE), CJD, ALS, Huntington’s, Parkinson’s disease, and many Cancers and cancer-related syndromes.
The work unit we used was a p6054 which is part of the SMP high performance client for Folding@home.
Folding@home has made great strides with the new A3 SMP folding client; it scales very well across multiple physical cores as well as Hyper threaded cores. As you can see, clock speed and memory speed play a huge part in SMP folding performance. The Folding@home SMP client has a large working set as the simulation needs quite a bit of memory. We can see that memory bandwidth has noticeable impact on performance. The Corsair Vengeance 8GB kit is once again right on the heels of the Kingston HyperX 4GB 2133MHz kit. For the price and capacity the Corsair kit is giving up very little in performance.
