[BOINC] [天文类] MilkyWay@home

http://milkyway.cs.rpi.edu/milkyway/

Milkyway@home is a research project that uses Internet-connected computers to do reserach in modeling and determining the evolution of the Milkyway galaxy.

研究银河系的建模和演化。

Milkyway@home is based at the Rensselaer Computer Science Department. This particular project is being developed to better understand the power of volunteer computer resources.

CS系主持的，似乎物理方面的研究内容并不那么重要，主要还是为了更好地了解志愿计算的能力。

最近几天有任务包了，每台主机最多同时下载8个。

心路历程

项目好像暂停了！！！

taoran

现在包不少呢，可以同时下载20个。

Mr.Cancel

带屏保？

sakeki

了解志愿者计算能力？

这都行？岂不是白算？

We've made a change to our validator which basically puts a speed limit to the amount of credit any given host can be awarded (per cpu). While this shouldn't effect the vast majority of our users (as the speed limit is quite high), it should protect the project from users who would like to cheat the project to get excessive credit.

调整了服务端的结果验证程序，对任务单元的得分加了限制，应该可以防止那些作弊的用户（对绝大部分用户没有影响）。

The deadline has been increased to 3 days (up from 2), mainly for computers that need to go offline for weekends. Hopefully this should work well for everyone.

任务单元的超时期限升至3天，主要是针对那些周末关机的计算机。

Due to some problems with multiple processor machines, I've increased the WU queue back to 20, but I've lowered the deadline for WUs to two days. Hopefully this will help keep peoples machines crunching without any downtime. We're still looking into a way to get a per-core queue and hope to have that going soon.

我已经将任务单元队列的长度恢复到了20，同时将超时期限调整成了两天，希望这能更好地让志愿者的计算机不至于闲着。我们也在寻找方法使得任务队列是针对每个处理器核心的。

新加此项目后，第一个WU有了以后，赶快nomorework，否则它按10分钟计算一个下WU，把人撑死。等第一个WU做完再allowmorework

俺一双核，没注意，竟然一口气下了20多个WU，实际计算每个WU需要3-9小时不等，3天哪能做完啊

这个项目不错………………

I've just finished implementing a bunch of optimizations suggested by our users in the new milkyway application (we're hoping to roll it out on wednesday). On our AMD Linux cluster it's running about 2-3x faster. I'm currently getting some numbers for OSX and Dave is working on some numbers for windows. We should be releasing the code wednesday when we put the app on our server.

项目方刚刚完成了计算程序的优化工作（希望能在周三发布），在项目方自己的AMD集群上速度提升了2到3倍，目前还在继续做一些测试，优化程序正式发布的时候会同时发布源代码。

Youth

I just implemented another round of optimizations, and now on the AMD Linux cluster it's running 8x-9x faster (almost 4 times as fast as the previous version). The machine I'm testing on is really high end, so I'm hoping that older archiectures will get even more improvement from this. Also, we're still on schedule to put the new app on the server this afternoon and start with the new workunits.
--Travis

继续优化，再次提速4倍左右，我们计划今天下午正式发布这个新计算程序及相应的新计算任务。

Youth

Nate came to us with some problems in the current application code, so we've been working on fixing that. Everything is looking right (or very close to it) at the moment, so we'll be trying to get the new application out this afternoon (around 2pm EST).

目前看上去一切正常，我们准备在今天下午发布新的计算程序（美国东部时区下午两点）！

Youth

We've put the new version of the application up on the server, currently we only have it for windows. I'm working on compiling the application for OSX at the moment. Afterwards I'm going to try to start a few workunits tonight and see how horribly things crash.

新计算程序已正式发布，目前仅支持windows平台。
