使用 NVIDIA GPU 运行 SETI@home （beta测试）

非常好，我已经装上了6.4.5客户端，系统支持CUDA。目前seti@home beta正在计算一个90小时的包，等算完了，周末一定试试GPU的包

vista 64下面装x64的BOINC都是计算错误

36分钟，3包算完
虽然有CPU占有，但期间偶见X87，几乎未见MMX/3DNOW！以及SSE/SSE2指令流过CPU，μops处在系统必须的常态量水平上，偶有极端增高但仅仅一瞬间而已，IPC也极低……不知道CPU被占来干啥了……而且每个包的CPU状态并不 ...

得分如何？平均每小时多少分？
用什么软件可以看到程序使用了多少SSE/SSE2/...指令？

想知道得出结果的得分情况以及rac对比。。。

等程序没啥大问题了，指令集优化的事情应该会有志愿者来完成：）

Thanks Martin :>) The GPU ap on Beta is from Berkeley gents. They get the kudos for it & have done a great job in getting a complete multi beam application working w/ all analysis functions. It's a HIGHLY impressive accomplishment and will provide a good foundation to base some optimizing efforts once it completes Beta & goes to public release.

Current GPU efforts @ Lunatics have made significant progress towards an Astropulse application on GPU. There's still lots to do, but progress is being made including some "new approaches" into how the data is crunched and potential opportunities to exploit multithreading etc. As you may have guessed, Jason, Joe, Raistmer, Mimo, Heinz, Richard & Urs are in heavy collaboration & testing. Actually, there are several efforts underway....improving stock AP performance/accuracy, optimizing AP for CPU as well as both AP GP and MB GPU undertakings. Some techniques and "lessons learned" have relevance in more than one area of focus. Having a better understanding of how the Beta MB GPU ap works, behaves and performs also has some relevance to what the gents are doing.

I'll leave any more info/detail to the resident experts ; >)

There's some neat things happening right now that should make for a fun 2009.
Cheers!!

发帖的是Gecko_R7，他说Beta项目中的GPU程序是项目方自己开发的，同时也为志愿者的优化工作打下了良好的基础。

另一方面，志愿者那边，在Astropulse子项目的GPU版本上也已经取得了较大的进展，虽然还有不少工作要做。（再次感谢Jason, Joe, Raistmer, Mimo, Heinz, Richard及帮助测试的志愿者）

ATI will be supported in a future version of BOINC, their developers are working with the BOINC developers and projects to port applications. This will take several more months though.

这个发帖的是Ageless，说BOINC以后的版本也将支持ATI的GPU，ATI的开发人员正在于BOINC的开发人员、计算项目方等协作进行移植工作，可能还需要几个月的工作量。

现在seti的gpu版运行在beta项目，一方面说明程序的问题可能还比较多，参加的人要有心理准备，另一方面，应该也是项目方希望的，如果参加了beta测试，最好能够多去官方论坛看看，参与一些讨论，报告一些问题，提出一些建议，等等，这样才能为项目做出更大的贡献，项目方也能因此尽早推出正式版本：）

电脑变得好慢。
看起来GPU没满载，像素流水线没用上，俺的GPU满载可以上100度，在用了cuda一直是75度。
