[BOINC] [天文类] MilkyWay@home

Youth

May 21, 2009
I've released a preliminary version of the CUDA application in the code release directory. For more detail, there's a forum post here. This should run on the same test samples, however I'm having some issues getting a working makefile/build script using both BOINC and the CUDA libraries, so if anyone has some knowledge about how to do this it would be really appreciated.

初始版本的CUDA计算程序已经发布了：

I missed a couple files in the previous release, so theres a v0.02 in the code release directory now.

之前发布的版本少了几个文件，所以就有了现在的v0.02版本：）

John has made the following post in the science section. It's an in depth explanantion of the current astronomy work being done here and quite readable and easy to understand (even I can get it). I recommend it if you'd like to know a bit more about what's going on here on the astronomy end of things.

解释本项目的研究内容及进展，有兴趣的可以看看~~

ProfessorNewberg has gone through all the steps to allow MilkyWay@Home toactually accept donations and has written a letter of request, whichI've posted here.The letter discusses the progress we've made in both scientificcomputing and astronomy, as well as our current funding situation. Youcan directly access the page to make donations here.

项目开始接受捐赠。

下面的帖子说明了项目当前在科学计算和天文学研究方面取得的进展，以及为什么希望得到捐赠的原因（NSF提供的经费到今年底就结束了，项目方希望能在2010年夏天继续得到NSF的资助，但即便成功，中间也存在半年的间隔期）：

请问 milkyway 能 CPU 跟 GPU 同时算吗 ? 若能的话如何设置呢

The CUDA application has been released on BOINC, please see this thread for more information. The Milkyway@Home team appreciates your patience in reaching this milestone. This code has been implemented and tested on the GeForce GTX 285 donated by NVIDIA to the Milkyway@Home research team.

CUDA版本的计算程序已经正式发布！

不清楚，我没有gpu可以算，帮顶一下吧~~~

CUDA要求还挺高的……

The CUDA application for 32 bit Windows has been deployed on BOINC. In terms of hardware a NVIDIA GPU supporting Compute Capability 1.3 is required. The following GPUs: GeForce GTX 295, 285, 280, 260, Tesla S1070, C1060, Quadro Plex 2200 D2, Quadro FX 5800, 4800 are known to have CUDA 1.3 support. The GPUs also need to have 256 MB of Video RAM and NVIDIA Driver 190.xx or higher needs to be installed. If these prerequisites are not met the CUDA application will not be downloaded through BOINC.

我用了二张 ATI 4850 可是只有一张会运算 , 换了 Boinc 6.10.3 也只有显示抓到一张而以
有人知道怎么同时使用二个 GPU 吗 ( XP 抓的到二张卡 , 第二张卡有装 DVI to D-SUB 的转接头 )

双精度……我的G92核心基本上废了，看来GT200的优化越来越完全了……

關掉crossfire

universebreaker 你好,

我并没有使用 crossfire , 二张卡的 crossfire 并没有连接 , 进到 Boinc 都只抓的到 GPU0 也就是第一张 , 第二张抓不到
但 CCC 及其它的程序查看都可以确认二张卡 windows 都已经可以视别 , 旁边的 everest 可以看出只有第一张卡温度上升 , 第二张待机中

先把windows xp更新到sp3
再把其他更新都裝好後再試試...

己经将 xp 升级到 SP3 了 , 芯片组程序也更新了, boinc 6.6.36 及 6.10.3 都用过了 , 结果都一样
机板为 Gigabyte 965P-DS4 , 不知道是不是 965 芯片的问题
CCC 为 8.12 , milkyway 优化为 0.19f

OK, 我这边已经可以运行GPU版了，在状态上显示运行中0.3 CPUs

我想问问怎么设置只能运行一个任务，几个WU一起运行很容易VPU重置……屏幕黑一下的感觉很不好受……

我的WU之前黑了好幾次之後
原本同時間跑6個
自動變成了跑3個
就沒事了
