E@H支持A卡了

http://einstein.phys.uwm.edu/forum_thread.php?id=9446
After more than a year of work by Oliver Bock, Bernd Machenschalk, Heinz-Bernd Eggenstein and other developers, we are pleased to announce the release of the first Einstein@Home application for ATI/AMD Graphics Cards.

This OpenCL application, which searches Arecibo data for new radio pulsars, is about a factor of ten faster than the same search running on a typical CPU. The application is currently available for Windows and Linux computers with Radeon HD 5000 or better graphics cards. We hope to have a version for Macintosh (Apple OS X 10.8, Mountain Lion) sometime this summer, but there are still some problems that need to be fixed or worked around.

Volunteers who wish to run this application will need to install version 7.0.27 or later of the BOINC client. Please see this thread for more information, or if you want to ask questions.

Many thanks to the AMD/ATI team for their support in the OpenCL software development effort.

Bruce Allen
Director, Einstein@Home




大概的意思就是现在支持A的GPU计算了
需要HD5000以上级别
只支持windows和Linux系统,水果系统大概要到夏天才能解决一些问题
BOINC版本需求7.0.27

嗯,老项目也算是跨入gpu时代了:)

    你那么支持 也该上一块显卡 继续计算哦

    嗯,最近工作上有些变动,手头一台能用的台式机都没了。。。只能等稳定下来再做考虑咯:)

    嗯,n、a都支持才算是完整跨入嘛:)

5系列以上才支持?白加入了

GPU速度貌似受cpu空闲程度影响,如果cpu一直是100%使用率opencl会比有空闲cpu的时候慢几倍.....不爽

    GPU项目也要用CPU,通常标明用1%的CPU+100%GPU,总之占用很少,但是还是要用。也有的项目要用到(号称)23%的CPU+1个GPU。

refla 发表于 2012-5-26 08:13:35

CUDA 也要占 CPU 的,哪个项目都不例外。。。

Rojer 发表于 2012-5-27 09:11:54

我明白,只是感慨一下降速太多,milkyway也有降不过没有那么多。
你们的GPU能跑到满负荷么?我总是在60%-40%之间啊。

    不知道你的问题有没有解决,如果没有的话,可以在官网项目参数里设置一下 GPU utilization factor of BRP apps
