Application v0.2 Code Release
November 22, 2008

I've released the code so feel free to download it and take a look. There's some more information about the code in the forums here. Please use the code discussion forum to post suggestions so we can further optimize and improve the code.

发布了新计算程序的源代码,有兴趣的可以去看看:)

New Application Version & Linux
November 22, 2008

I've updated the code of the new app to fix the progress bar errors, so let me know how it's working (when you get version 0.2 of the app). I've also compiled an x86_64 linux binary (and I think Dave will be compiling an i686 version), so there should be a new version (and linux versions) available whenever dave wakes up and has time to sign the binaries and put them on the server. I'll be posting the new code online sometime today or tomorrow, and I'll update the news when it's available.

修正了进度显示错误。

WUs for New Application
November 21, 2008

I've started a few WUs for the new application. Please let us know if these are working.

发布了一些用于新计算程序的任务。

New Application 4
November 21, 2008

We've flagged the new application as a test application, so you can opt out of testing it. Default preferences are to NOT run test applications, so if you want to help us test it you can enable this in your project preferences.

新计算程序目前是标记为测试程序,如果你想要帮助我们测试的话,请在你的项目参数中进行设置。

New Application 3
November 21, 2008
We've fixed the problem with the application and have recompiled it for windows and OSX. I'll be starting up some workunits tonight (in the next few hours) and hopefully they'll work ok. If the workunits don't fail, I'll start up the new assimilator.

这个项目给分太慷慨了,我一台老机器~赛扬1.7的CPU,不到半小时就能算完一个10多分的包

boinc邮件列表中提到有志愿者为这个项目开发了ati版的gpu计算程序,效率提高非常非常多,具体情况有兴趣的可以去官方论坛上看看。

GPU Project Status
April 11, 2009
So I've been working on making the new project specifically for GPUs. This is will alleviate the no work situation because we will be giving much longer workunits to GPU clients. However, I've discovered a bug in a python script that was made when compiling. I need labstaff to give me permission to overwrite the file, but am not sure they work on weekends. So hopefully by early next week we can have a new project up!



看来8秒一个WU的时代一去不复返了。。。

看你的CPU最高支持到哪个指令集就用哪个咯~
当然,GPU满足要求的话,肯定用GPU了~

这样更好吧~
毕竟8秒一个WU,上传下载WU就够你受了……

Looks like I've finally gotten the CUDA application working. I'm in the process of cleaning up the code, and it should be available for you to play around with tonight. It's my first crack at a CUDA application, so it's a bit rough, but currently it's crunching the current stripe 82 WUs in around a minute using a GeForce 9600M GT. I'm sure there's quite a bit more optimization we can to do get it running even faster, as this is the first version and not optimized at all. Part of the reason this has taken so long was that I was doing quite a bit of testing comparing double and single precision math on the GPU. I've come up with some schemes that will allow us to use older graphics cards which don't support double precision math (like the GeForce I've been using); which should let a lot more of our users be able to use the GPU application. More news later when I post the code.

CUDA版本的计算程序终于搞定了,今晚应该就会分发出来。从目前的计算速度来看,还有进一步优化的空间。我还准备想点办法让那些比较老的显卡(不支持双精度计算的)也能跑上我们的项目。
