CAS@home computing schedule
Thanks to all the generous contribution from our volunteers, TreeThreader has finished its first computing campaign of 50K protein sequences. Very important scientific conclusion has been drawn from the results and a new paper is in the process of writing. Official results will be published later on CAS@home news.A new campaign of TreeThreader will be launched soon with a task of 80K sequences to be predicted!

感谢各位志愿者的热心帮助,TreeThreader已经成功完成了第一批的计算任务,成功破解了5万条新蛋白质序列的结构。基于这些计算结果,生物学家在利用海藻提炼石油的研究方面已经得出重要的科学结论,目前正在撰写相关论文。CAS@home后续会继续公布正式的科学结论。TreeThreader后续将有更大的计算任务(约8万条蛋白质序列),目前计算任务正在部署中。

TreeThreader Job Submission Error
Due to network problems between ICT and IHEP, the TreeThreader job submission service keeps failing. In order to diagnose this problem, the job submission service will be stopped, hence no jobs will be generated during this period. We will send notifications once the service is back! Sorry for the inconvenience!

Updates:
ICT has started to slowly submit jobs from last week to test the stability! (28th Aug, 2013)


由于网络故障问题,TreeThreader 的作业提交系统不断出现失败,为了诊断故障,我们决定暂时中止TreeThreader的作业提交服务,因此这段时间内CAS@home上将没有可领取的作业。我们会在解决问题后,及时通知!带来不便,敬请谅解!

更新:
计算所的前端作业服务器开始小规模地提交作业,测试系统的稳定性,一切还在恢复过程中!(2013-08-28)

CAS@home back in service.
We have finished the regular maintenance of our servers, and CAS@home is back in service now. 21 Jul 2013, 11:30:10 UTC · Comment


cas@home downtime
IHEP-CC which is hosting CAS@home will be under regular maintenance between 19th July and 21th July. In the meanwhile, we will also shut down CAS@home server because of no network connectivity. The project will resume its regular running at the latest of 22th July 2013. 19 Jul 2013, 1:55:18 UTC · Comment


Tips: experiment about ICT task cannot be stopped.
近期有志愿者反映ICT的作业在windows上出现无法手动停止的问题,这个问题出现在ICT_treeThreader_1.21_windows_intelx86(2nd Generation)版本,具体现象是在BOINC里手动暂停ICT的任务,但是windows的任务管理器里面还有,而且是满负荷运算,直到把当前任务完全计算完才停止。
针对这种情况,本人在自己电脑上测试了下,BOINC客户端参数设置如图1。具体测试情况如下:
1)启动CAS@home,更新任务,得到8个ICT任务,版本是ICT_treeThreader_1.21_windows_intelx86(2nd Generation),开始运行后,CPU利用率为100%,见图2
2)对其中4个任务暂停,CPU利用率会降到50%,见图3
3)如果对项目暂停,本人的机器上是可以把ICT的进程停下来的,此时利用率也降下来了,见图4
如果把boinc客户端上的任务先停掉,过一段时间再继续,根据boinc服务器端的设置,客户端会再拿到8个任务,这个时候把所有任务暂停,会遇到ICT的进程不会立刻停止,待过一段时间后ICT的进程就停止了,见图5图6
最后建议:为了防止CPU利用率出现100%的情况,可以在boinc客户端选项里把最多可使用的CPU利用率设置低一些,比方说50%。

Recently, some volunteers reflect that the ICT tasks cannot be stopped manually in the windows machines, and the problem occurs in the version of ICT_treeThreader_1.21_windows_intelx86(2nd Generation. Specific phenomenon is described as follows. When the ICT task is stopped manually in BOINC client, it also exists in the task manager and full load, and it cannot be stopped until the task is totally calculated.
To solve the problem, I test it in my own machine; the parameter of BOINC clients is as picture 1. The detailed situation is as follows:
1)Start the CAS@home project, and refresh the task, then the client will get eight ICT tasks, and the version is ICT_treeThreader_1.21_windows_intelx86(2nd Generation). Then run the task, the CPU usage ratio rises to 100%, as shown in picture 2;
2) If suspending four tasks, the CPU usage ratio reduces to 50%, as shown in picture 3;
3) If suspending the whole project, the ICT progress can be killed in my machine, as a result, the CPU ratio comes down, as picture 4.
If stopping the task in the BOINC client, and then continue it, according to the configuration in the BOINC server, the client will get eight more tasks. The ICT process cannot be stopped immediately until after a while if suspending all tasks, as shown in picture 5, picture 6.
Final recommendations: To avoid the situation of CPU usage ratio rising to 100%, it can lower the parameter of most used CPU in BOINC client to a low value, for example 50%.
