我们算得LHC@home是干什么的?

lawrence

如题!我算了几个包,感觉错误的很多,有的几秒就玩了,好像是劣质品
而且一个包5个人算!!!
如果真的是实验的数据,那也好,就怕不是啊!! 我在他们的网站看到他们好像有自己的计算网络阿,那我们是干什么的阿,呵呵
我把seti和E都停了,
不知道值不值得阿,请高手解释阿,那些英语的介绍,实在是看不下去啊!!

lhc对科学的进程影响重大，你说值不值？

最早这个项目应该是辅助lhc的设计吧，按理现在都开工了也没啥好设计的了（以后有大的升级不算。。。），但近期下载的任务也似乎都还是n年前的那个计算程序，sixtrack什么的，不清楚实际意义何在。lhc现在正式运行后，核心的或者说主要的数据处理任务肯定是轮不到lhc@home的（参见相关的介绍文章，cern自己的计算处理能力是相当强的），但可能会有一些同样是辅助性质的计算任务吧。

对这个项目的了解比较少，如果说得不对欢迎指出错误：）如果英语ok，建议可以多关注一下lhc@home的官方论坛。

When, if ever, will LHC@home be crunching actual LHC data in WUs?

In short, we won\'t be. The actual messages are over several threads, one is here.

Snippets for a quick read are below


Not a chance, a single dataset which a machine needs would be at least 1 gigabyte of data and your machine would have to download that before it could do anything else. We are TRYING to find something from the analysis of real data that will port but the big four have told us that the code is too, lets say, verbose.

and

We have a second project it\'s called the Grid. The LHC\'s computing needs are being fulfilled by that IF we can get something ported to BOINC we will but I reiterate we have no money. Also it\'s not just the download are you all willing to have large, hard drives, massive broadband connections and run only Scientific Linux (CERN edition) and not use your machines for anything else?

and

However this would require a person to port the software from the current Grid setup to BOINC and for the Grid software to be actually portable. Not only do we not have this person (see the money issue above) we have also been told that there is no way the applications the Grid runs are lightweight enough to be ported to BOINC. We keep prodding and asking about simulation applications/other experiments etc but nothing so far.


Hope this helps

lhc@home不会处理lhc的运行数据。后者是由cern自己的网格来处理的，由于多方面的原因，不适合于迁移到BOINC平台。

Hi there,
We still have some more tuning to do on the LHC and your help for that is appreciated.

We also have some other particle physics projects in the pipeline.

应该还会有一些sixtrack的任务（比如在进行新的实验前，帮助调整lhc的运行参数之类的），以后也可能有其它一些粒子物理的项目。

阿,再次谢谢youth阿....看来每那么重要啊,,
继续seti和E```

重要倒还是重要的，主要是这个项目对计算力的需求不大，所以每次有点任务出来很快就被抢光了
