爱因斯坦在家
by Yan
前面介绍过爱因斯坦在家(Einstein@Home),它是World Year of Physics 2005(2005世界物理年)的一项活动。现在,它的测试版发布了。
Einstein@home is a program that uses your computer’s idle time to search for spinning compact stars (such as pulsars) using data from the LIGO and GEO gravitational wave detectors. We plan to deploy a production version of Einstein@home around the end of 2004, as part of the American Physical Society’s World Year of Physics 2005 activities.
We have just completed our first test release of Einstein@home, and would like to solicit your help in testing it. Please be aware that this is not a production version of Einstein@home: it is an early (alpha) test release, which has undergone only limited testing within the LIGO Scientific Collaboration and GEO project.
参加这个活动,你需要下载一个程序,这个程序会在你计算机空闲的时候运转,下载数据,分析数据,然后把结果传回去。你可以设置占用计算机的资源比率。我运转了一天了,资源占用很小,感觉不到它的存在。目前的工作是在搜索脉冲星。
这相当于让自己计算机的闲置时间做些志愿工作,我觉得很有意思。而且想法也很好,是一种分布式计算,互联网上计算机群,力量远远大于现存的超级计算机。想象将来有一种简单易用的手段,能让我们像使用bt下载那样,在一个计算机朋友圈里运行自己的科学计算程序。这比现在计算机互联,但互不协助的状态合理得多。
我建立了一个team,如果你参与这个活动,欢迎加入这个team。
我喜欢这东西
E@H及其它分布式运算相关可以去www.equn.com看看,比较集中:)
[…] 2004年的时候,我介绍过这个 Einstein@Home,并在单位的机器上跑过它的程序。我还建过个 team。后来因为工作变更停止了。这条新闻提醒了我,我又把它给运行上了。:) Einstein@Home is a program that uses your computer’s idle time to search for spinning neutron stars (also called pulsars) using data from the LIGO and GEO gravitational wave detectors. Einstein@Home is a World Year of Physics 2005 project supported by the American Physical Society (APS) and by a number of international organizations. […]
