[分享] Einstein@Home 项目新闻

Jan 4, 2005
In anticipation of 'going public' Einstein@Home is now running on the new server hardware. We need to complete and test (hopefully) one final round of application revisions before this happens. Hopefully this will eliminate the remaining problems with SIGABORT failures in the Linux application and similar problems (and a useless docked window) in the Macintosh application.
2005年1月4日
为了能尽早'正式开始'，Einstein@Home现在在新服务器硬件上运转。在这之前，我们需要完成并测试(希望如此)修正版客户端。希望能解决剩下的Linux应用程序的SIGABORT故障和Macintosh应用程序的类似问题(和一个无效窗口问题)。

In the next several days we are going to shift from using the current BOINC scheduler to a new BOINC 'locality' scheduler. This will have some important benefits. In particular, it will ensure that host computers get lots of work for the (large) data files that they have already downloaded, instead of being required to download a new large data file for each new item of work. It will also remove these large data files from the host computers when they are no longer needed. Unfortunately the new scheduler is not compatible with the test workunits currently in progress on many hosts. Testers, please note that for this reason, we will be forced to cancel a number of workunits currently in progress, when we shift to the new scheduler.
2005年1月12日
在这几天里我们将要把现在使用的BOINC调度程序更换为新的BOINC'本地'调度程序。这将有一些重要的好处。 尤其，它将保证主机不再为已经下载了的(大)数据文件所累，按需下载一个新的大数据文件中的文件，而不再下载全部文件。当他们不再被需要时，它也将从主机删除这些大的数据文件。令人遗憾新调度程序与当前在很多主机上进行中的测试workunits不兼容。因此，内测人员请注意，当我们转到新调度程序时，我们将被迫删除许多当前进行中的workunits。

IMPORTANT NEWS: David Anderson, the creator of BOINC, has found and fixed a serious bug in the BOINC 'core client'. This causes failure of a job if the download of any of its input files fails (the correct behavior is to retry and complete the download, then run the job). Moreover, any other job that used the same files would also fail. A fixed core client should be available soon. This should make Einstein@Home work much better and eliminate the main source of job failure
2005年1月13日
重要消息：David Anderson，BOINC的创造者，已经发现并修正了一个BOINC '核心程序'里的严重漏洞。如果它的任何输入文件的下载失败，这将导致一个任务的失败(正确的行为是重试下载并完成下载，然后，才开始工作)。而且，使用相同的文件的任何其他任务也将失败。不久应该会发布一个修正版的核心程序。这应该使Einstein@Home更好地工作并且消除任务失败的主导因素。

To prepare for the upgrade of our scheduler, we are not providing new work for the next day or two. We are taking this measure to try and minimize the amount of lost credit and to make the transition to the new scheduler as smooth as possible.
2005年1月14日
为我们的调度程序的升级作准备，接下来的几天我们不提供新任务。采用这种方法我们可以尽量把丢失的积分数量减到最小并使新调度程序的转换尽可能顺利。

As explained in the news item from Jan 13, below, the BOINC 4.13 core client contained a serious bug that has now been fixed. Einstein@home users: please upgrade to the BOINC 4.14 core client, which can be found halfway down this page.
2005年1月17日
如1月13日新闻里所述，BOINC 4.13核心程序包含一个严重的漏洞，现在它已经被修正了。Einstein@home用户：请将BOINC核心程序升级到4.14版，这里是下载页面。

Jan 18. 2005
We have cancelled the remaining "old scheduler" workunits, and started testing the new locality scheduler. This should send work to hosts that already have the correct data input files, greatly reducing the download demands on host computers and the Einstein@home server.
2005年1月18日
我们注销了现有的"旧调度程序"的workunits，并且开始测试新的本地调度程序。它会把任务发给已经有校正后数据输入文件的客户端，大大减少客户端和Einstein@home服务器的下载带宽需求。

The BOINC developers have released a new version of the client (4.15) that fixes a bug that caused some lost work for CPDN users when they were upgrading the client. Please upgrade to 4.15 as soon as possible.
2005年1月18日
BOINC开发员发布新版客户端(4.15)修正了一个BUG，它将导CPDN用户在升级客户端时，会丢失一些任务。请尽快升级至4.15。

项目正式开始，2月19日开放注册！

已经注册，开始算了

In the two weeks since our public launch, Einstein@Home has gone from about 6,000 users (with credit) to over 20,000, and is currently adding users at the rate of about 1,000/day. Apart from one 30-minute crash, the project server has been operating stably; we estimate that it has the capacity to handle about ten times the current number of users, hosts and workunits.

2005年3月5日
项目正式开始后两个星期内，E@H的用户已经从大约约6000名增加到超过20000名，目前保持大约每天1000名的增长速度。在一次为时半小时的故障之后，项目的服务器已经正常运行，我们估计目前的服务器配置可以容纳十倍于现在的用户，主机，计算包数量。

We had a short outage today that resulted from the kernel running out of memory and killing the database.
You may have noticed problems connecting to the scheduler or the forums.
2005年3月8日
今天我们当一会儿机，导致内存溢出并且数据库也被破坏了。
当你连接调度程序或者论坛时你就会注意到这个问题。

怎么到处停电？

好像这里的outage应该是停止服务，而不是停电

已修正

A data download mirror is now being hosted by the PSU LSC group. Einstein@Home
users in the US Eastern Time Zone will now try to get data from this mirror first.
2005年3月14日
PSU LSC小组现在开了一个数据下载镜像服务器。在美国东部时区的Einstein@Home用户现在将首先尝试从这个镜像服务器下载数据。

March 18, 2005

A data download mirror is now being hosted by the MIT LSC group. Einstein@Home users in the US Eastern Time Zone will also use this mirror.

基本同上，在MIT又开了个数据下载镜像服务器。

A new version of the validator (Teviet Creighton) is now in use. This should reduce the numbers of results which are incorrectly marked as 'invalid'.
2005年3月6日
启用一个新的检验程序(Teviet Creighton)。这应该会降低被误标为'无效'的结果的数量。

The Einstein@Home server will be shutdown on Fri Apr 8 19:00 UTC for approximately one hour for maintenance.
2005年3月6日
Einstein@Home服务器将于4月8 星期五19：00 UTC关闭大约一小时以进行维护。

April 7, 2005
During the next few days we will finish the first round of S3 analysis and begin a second round. As we finish up the first round of S3 analysis, users may find that they are getting a new data file with each workunit; users with modem connections may want to suspend Einstein@Home for a few days to avoid multiple long downloads. Note that there may also be some instability in a few days as we shift to new workunits.
在接下来的几天，我们将完成S3分析的第一阶段，开始下一阶段。完成第一阶段期间，用户会发现计算每个wu都需要下载一个新的数据文件，窄带上网用户可以选择暂停运行Einstein@Home项目几天以避免经常性的长时间下载。另外，在接下来的几天，系统可能会不太稳定。

A bug-fix in the Einstein@Home scheduler about 20 hours ago introduced another bug which prevented the scheduler from responding properly in many cases. This has been fixed.
2005年5月1日
大约20小时前我们修改了Einstein@Home调度程序的一个BUG，但这引发了一个新的导致调度程序有时出现异常的BUG。不过这个新的BUG已经被修正了。

May 3, 2005

We have finished the first complete analysis of the LIGO S3 data set. Based on this, the data preparation and cleaning process have been modified to remove a number of instrumental artifacts that appeared in the post-processing stage, and a new data set has been prepared. This new data set uses the final S3 time-domain calibration and also includes a number of 'software simulated' fake source signals. After we have completed analysis of this final S3 data set (a few weeks) we will to move on to the new and more sensitive S4 data set.

我们已经完成了S3数据集的第一轮全面分析。数据的准备和清除过程均进行了相应的修改以去除后期处理阶段中的许多仪器导致的不正确结果，一套新的数据集也已经准备好。这套数据集使用的是经过时间域校正的S3数据集，并在其中引入了一些人为模拟的假信号源。在我们彻底完成这个S3数据集的分析之后，项目将转向全新的、更灵敏的S4数据集。

The Einstein@Home server crashed again on June 09 at 20:20 UTC. The server was rebooted and everything appears to be working correctly now. This crash was unrelated to the previous crash on May 26 which we now know was the result of a motherboard failure.
2005年6月9日
Einstein@Home服务器在6月9日20:20 UTC再度崩溃了。服务器已经重新起动了，现在看上去一切运作正常。这次崩溃与上次－－5月26日的崩溃无关，我们现在知道了上次崩溃是由主板出错造成的。

Interested users can help us now by testing our "Beta Apps". Instructions for installing them can be found on this page. The current Beta Apps feature a fix for the ATI graphics driver issue (Windows) and working screensaver and fast AltiVec science code (MacOS). .

有兴趣的用户可以帮助我们测试Beta版应用程序。相关的指导可以看这个页面（[url]http://einstein.phys.uwm.edu/app_test.php[/url]）。当前的Beta版程序主要特性有：修复了WINDOWS平台ATI显卡的一个问题；MacOS平台上可用的屏保，fast AltiVec science code（这个好像是是一个类似于SSE之类的指令集的东东，PowerPC提供的）。

The APS (American Physical Society) has setup a page about Einstein@Home. We just added a link to [url]http://einsteinathome.org/[/url] under the "More Information" information section of main E@H page.

美国物理协会刚搭建了一些Einstein@Home相关的页面。我们在主页面“更多信息”处添加了一个链接到[url]http://einsteinathome.org/[/url]。
