GeForce GPU Runs Folding@home Protein Simulations 140 Times Faster Than Traditional Processors

SANTA CLARA, Calif., July 24 /PRNewswire-FirstCall/ -- Stanford University's distributed computing program Folding@home has become a major force in researching cures to life-threatening diseases such as cancer, cystic fibrosis, and Parkinson's disease by combining the computing horsepower of millions of processors to simulate protein folding. The Folding@home project is the latest example in the expanding list of non-gaming applications for graphics processing units (GPU). By running the Folding@home client on an NVIDIA® GeForce® GPU, protein-folding simulations can be done 140 times faster than on some of today's traditional CPUs.

"The impact of GeForce GPUs on protein folding simulations was immediate and dramatic," said Vijay Pande, associate professor of chemistry, Stanford University and director of the Folding@home project. "Teams that are folding with GeForce GPUs are seeing their production skyrocket. Applying that kind of processing power to Folding@home changes the whole dynamic of the project and could significantly reduce the time it takes to carry out our biomedical research."

The Folding@home project has amassed a large following of computer enthusiasts who compete in teams to churn through as many data units as possible. Their unofficial stats are organized by and displayed at ExtremeOverclocking.com. It took the NVIDIA internal folding team only two weeks to move ahead of 90% of all teams, using only 10 machines. After expanding the team to include more GPUs, the NVIDIA team has moved inside the top 0.1% of teams in all-time total production in less than a month.

Other folding teams are also seeing their status rise as a result of the NVIDIA Folding@home client.

"We saw the completed work double for our PC Games Hardware Folding team as a result of many team members installing the NVIDIA Folding client," said Carsten Spille, editor at PC Games Hardware. "We are passing many teams every day and we have finally reached our goal of being one of the top 100 folding teams in the world

140X，就算按照两个GTX280 算，这传统CPU 也太渣了吧？

F@H这种应用也很正常啊。
FFT传统cpu还被三四百M的Ti虐呢{titter:]

标题: 回复 4# boris_lee 的帖子
按照峰值计算，理论峰值，GTX280 就算1.3TGFlops，这种事情很难发生，即使是FAH，两个2.6TFlops，除以140X，那么所谓传统CPU 的性能不过是不足20G。
20G 什么概念？一个Q6600不超频可以达到32G。

古老的E6700的峰值都达到21.28GFLOPS。

按照峰值计算，理论峰值，GTX280 就算1.3TGFlops，这种事情很难发生，即使是FAH，两个2.6TFlops，除以140X，那么所谓传统CPU 的性能不过是不足20G。
20G 什么概念？一个Q6600不超频可以达到32G。

这个我不是很确定了，可能FAH的算法对CPU优化的不够好，中间等待I/O的时间过多？
反正标称几Gflops的p43.0 算FFT比标称1.8G FLOPS的虎鲨101差得远

大致上这半年的GPU FAH状况就是从AMD only时代的27TFLOPS，变成NVIDIA内测开始时代的143TFLOPS，然后是媒体发放（带动了诸如HardOCP等团队）的6月20日的541 TFLOPS，现在增长到1PFLOPS。

CPU按照单核计算就差不多了……1.3T/140=9G，32G/4=8G，大概差不多。

6月20日后发生的事情，留意GPU的咖啡线，PS3出现了巨大的抖动，据说是因为MGS4发售 {shocked:] ：

确定了
F@H的traditional是non-SMP的。{shocked:]
另外有个smp版本的，估计不作为tradtional计算

HPC client中的SMP是包含到OS statistics统计的。

FAH FAQ中有提到目前GPU2使用到CPU资源，完全off load to GPU希望在将来实现。
