[B]NEWS UPDATED![/COLOR][/B]

[U]July 28, 2004[/U]

The project is currently down. We found a bug in the scheduling code such that returned results were not being updated in the database. We are now running a fix script on the DB, marking each affected result as unsent so that it will be resent. Unfortunately, credit was not given for results affected by the bug.

太久没有做分布式计算了的项目了。

原本安装有Client的机器因为系统远程维护而被清除，实在遗憾。无奈CERNet却又很难同国外的的服务器连接上，也只好作罢。

等待吧。不想再继续旧的SETI@home，就等着这该死的新平台的SETI@home恢复正常吧。:)

（PS：巨大的数据库，有的“他们”忙一阵子了……）

We have shutdown the schedulers and file upload handlers so the transitioners can play catch up again. The transitioners keep falling behind because the DB is I/O bound. We believe that the new hardware we have coming online will resolve this issue. Until it is online we'll be continuing these rolling blackout style server outages.

The project is down while we deal with a backup problem. We hope to be back up soon.

The good news is that the scheduler is now running as a fast cgi which means it maintains a persistent connection to the DB. The load on the scheduling server has gone way down which is a good thing and the mysql server is using more CPU which is also a good thing. The bad news is that the transitioner is still way behind and so the project will probably run out of send-able work as early as 04:00 UT tomorrow. The transitioner is slow because the mysql server is IO bound. We are having Sun look at our IO system to see if it can be tuned to better performance. At the same time we are planning on moving the physical DB to a high performance Snap Appliance box in the near future. So we are hopeful that these IO problems can be solved.

We are now up and running again, during the night we generated 400k results to be sent out. Things might be a bit weird for awhile, somebody decided to launch a denial of service attack yesterday afternoon.

可以看出BOINC版的SETI@HOME还是很不稳定,问题多多.

这个贴应该放到SETI@home版，而不是BOINC版的。

这个就是基于BOINC下的一个测试.
