We will be having a 4 hour outage on Monday, 11/19/2007, starting at 10:00 PST.The purpose of this outage is to reroute many of the power cords for   the project servers, rearrange some of our UPSs and pull deprecated equipment out of   the server room.

项目将在太平洋标准时间11月19日周一上午10点(北京时间应该是20日凌晨2点)停电4小时。目的是为项目服务器重新铺置供电电缆、UPSs(不间断供电设备),还有从服务器房间清理废弃的设备。

Technical News 2007.12.11

Okay so the weekly outage is running long and still going strong as I write and post this missive. So be it. What's the deal? I'll tell you. Short story: we're trying to get a lot done today. We fully expected things to take a while, and our expectations are being realized. As we continue pushing forward on the analysis code, we needed to build another index on the master science database (thumper). This takes many hours, during which the table in question is locked and therefore the parts of the back end that require science database access have to be shut down, which is why we time such events with the regular outages. However, we're also finally tackling the nagging workunit space problem. Our workunit storage server (gowron) shares workunit storage space with various BOINC database archives, so the easiest/best solution is to move those archives elsewhere. Where's elsewhere? We currently have a lot of space in a volume established for science database archives on thumper. So today we had the two BOINC backups and the index build all hitting the thumper disks pretty hard, thus slowing everything down. Seems kind of silly, but this is a special case as we're not normally doing index builds. Nevertheless we'll move the BOINC database archives elsewhere at some point down the line as time/disk space permits. Meanwhile.. we broke the archive space on gowron and converted it all into a bunch of RAID1 pairs which are taking a long time to sync up. Actually, there's even more ex-archive space available but we'll do that at another time. My guess is the syncing should be done around 3:30pm Pacific Time. Are you getting all this? Warning: this entire chapter will be on the test. By the way, while waiting for all the parts above to come together I burned a Fedora Core 8 DVD and installed it on our latest Intel donation (mentioned in an earlier post). We're going to call it "bane" - actually reusing a name/IP address of another potential server donation that didn't pan out so well. I don't believe in jinxes, and I'm all for recycling. Anyway, it's already up and configured and working a lot better than the old bane. Might have a new web server racked up by the end of the week! And we got the mass mail pipeline finalized. Maybe I'll start those up today too. This is actually the highest priority but it's not very good form to start a mass mail while the project is down. - Matt

好了现在每周例行的停机时间有点长而且在我写这篇文章的时候看起来还要持续一段时间。我下面就简短地告诉大家到底发生了什么事。我们今天要做的事情比较多,在我们的预期中需要比较长的时间,现在看来我们的预计是正确的。在我们继续分析代码的过程中,我们需要在主科学数据库(thumper)中建立另一个索引。这需要好几个小时,因为这需要锁定数据表,方法是关闭所有访问数据库的终端程序。这就是我们每次停机都要计时的原因。但我们也终于解决了关于储存工作包的硬盘空间的麻烦问题。我们储存工作包的服务器(gowron)同时也储存着很多BOINC数据库存档,所以最好的办法就是将这些存档扔到别的地方去。那到底是什么地方呢?我们现在在thumper上还有很多空间,所以今天我们同时把存档和索引这两个占硬盘的东西都扔到了thumper上,所以就把东西都搞满了。可能你会觉得我们很笨,但是我们也没有办法,因为这次建立索引不像以往。但是我们以后在时间和磁盘空间允许的情况下会把BOINC数据库存档移走的。现在,我们把gowron上面储存存档的空间用作RAID1,这需要不少时间去同步。实际上,还有更多的空间可以利用,但是我们下次才搞。我估计在太平洋时间下午三点半应该就可以完成了。你们明白了么?在等待的时候,我刻了一张Fedora Core 8的DVD,然后在Intel新捐赠的服务器上装了。我们把这台服务器叫"bane",现在正在用另一台工作的不怎么样的别人捐赠的服务器的IP地址和名字。反正我不怕什么不祥物,而且还很环保。无论怎么样,这台服务器已经配置好了没有什么问题。周末可能会有一台新服务器,而且我们终于快发送完那一大堆电子邮件了。可能我今天也会把它们发完。这个就是目前来说优先级最高的任务了,尽管在项目停机的时候大发电子邮件看起来不怎么样。 -Matt

UC Berkeley Press Release: SETI@home looking for more volunteers.

SETI@home looking for more volunteers
By Robert Sanders, Media Relations | 02 January 2008
                                                                                                                                                                                                                        BERKELEY – The longest-running search for radio signals from alien civilizations is getting a burst of new data from an upgraded Arecibo telescope, which means the SETI@home project needs more desktop computers to help crunch the data.

Since SETI@home launched eight years ago, the project based at the University of California, Berkeley's Space Sciences Laboratory has signed up more than 5 million interested volunteers and boasts the largest community of dedicated users of any Internet computing project: 170,000 devotees on 320,000 computers.

Yet, new and more sensitive receivers on the world's largest radio telescope in Arecibo, Puerto Rico, and better frequency coverage are generating 500 times more data for the project than before. The SETI@home software has been upgraded to deal with this new data as the search for extraterrestrial intelligence (SETI) enters a new era and offers a new opportunity for those who want to help find other civilizations in the universe.

"The next generation SETI@home is 500 times more powerful then anything anyone has done before," said project chief scientist Dan Werthimer. "That means we are 500 times more likely to find ET than with the original SETI@home."

According to project scientist Eric Korpela, the new data amounts to 300 gigabytes per day, or 100 terabytes (100,000 gigabytes) per year, about the amount of data stored in the U.S. Library of Congress. "That's why we need all the volunteers," he said. "Everyone has a chance to be part of the largest public participation science project in history."

The 1,000-foot diameter Arecibo dish, which fills a valley in Puerto Rico, is part of the National Astronomy and Ionosphere Center operated by Cornell University with funds from the National Science Foundation. Since 1992, Werthimer and his team have piggybacked on radio astronomy observations at Arecibo to record signals from space and analyze them for patterns that could indicate they were transmitted by an intelligent civilization.

When the team's incoming data overwhelmed its ability to analyze it, the scientists conceived a distributed computing project to harness many computers into one big supercomputer to do the analysis. Since SETI@home was launched, other distributed computing projects have arisen, from folding@home to predict the three-dimensional tangle of a protein to the newly-launched cosmology@home to model possible universes. Most are now on a platform called BOINC (Berkeley Open Infrastructure for Network Computing), which was developed by SETI@home's director David Anderson so that the various projects could share resources.

"There are now 42 projects on BOINC, and, until now, there has been enough computing power to go around," Werthimer said.

What triggered the new flow of data was the addition of seven new receivers at Arecibo, which now allow the telescope to record radio signals from seven regions of the sky simultaneously instead of just one. With greater sensitivity and the ability to detect the polarization of the radio signals, plus 40 times more frequency coverage, Arecibo is set to survey the sky for new radio sources.

These improvements also prime the telescope for an improved search for intelligent signals from space.

"The multiple receivers help us weed out interference better and make us less susceptible to thinking that things terrestrial are extraterrestrial,"
Werthimer said.

Werthimer noted that, despite the fact that UC Berkeley has been analyzing radio signals from space since 1978 on various telescopes, no telltale signals from an intelligent civilization have yet been found.

"Earthlings are just getting started looking at the frequencies in the sky; we're looking only at the cosmically brightest sources, hoping we are scanning the right radio channels," he said. "The good news is, we're entering an era when we will be able to scan billions of channels. Arecibo is now optimized for this kind of search, so if there are signals out there, we or our volunteers will find them."

SETI@home has been funded by various organizations over the years, including the Planetary Society and Sun Microsystems, and continues to be supported by individual donations from its volunteers.

随着阿雷西博望远镜的升级,SETI@home 需要更多的志愿者参与计算!
新的更灵敏的接收器安装在阿雷西博上,频率覆盖范围比现在增强500倍。同时软件也将升级以处理新的数据来寻找外星文明,SETI@home将进入一个新的时代!
....
新的七组接收器安装在阿雷西博望远镜上,可以同时接受7个区域的信号,而之前只能对一个区域。另外更灵敏的能力,可以对40倍以上的频率范围检测偏振的无线电信号。
多重接收器帮助我们更好的消除干扰,并降低地面信号的影响。
我们正在进入一个新的时代,将能够扫描数十亿渠道。 阿雷西博正在优化这种搜索,因此,如果有外星文明的信号存在,我们和我们的志愿者会找到他们。
SETI@home 多年来一直受到各团体资助,包括美国行星学会和Sun Microsystems等,还有持续来自志愿者个人捐款。

Weekly Outage (每周停电维护通知)

Every Tuesday morning (Pacific time)we have a 3-4 hour outage for database maintenance. The upload/downloadservers and some web pages are offline during this time. Update: the outage is taking far longer than we'd like this week (will be about 6-7 hours total).

太平洋时间每星期二上午(北京时间每星期三凌晨) ,项目会有3-4小时的停电,对数据库进行维护。上传/下载服务器和一些网页服务将在这段时间关闭。补充:这个星期的停电时间会远多于计划(将约为6-7小时) 。

看来阿雷西博设备更新后,SETI@home的尾随工作接踵而至~
