Einstein@Home will be shutdown at 10:00 UTC on Sunday Nov 27 and should be back on within three hours. This maintenance time will be used to add larger disks to the database server. The extra space will be used to store backups and future results.

27日UTC时间10:00,项目暂停了三个小时以给数据库服务器添加更大的磁盘。新增的空间用于储存备份及以后的分析结果。

After almost five months of development and private testing, Einstein@Home will begin public testing and distribution of a new search application called "Albert". This is an improved and more sensitive version of the previous search code. Initially we will send out only a few hundred workunits for this new search, but if these are successful, we will begin broader distribution of these new workunits over the coming few days. If unexpected problems arise, please be patient, and look in the Problems and Bug Reports message board for additional information.

在经过五个月的开发及内部测试之后,Einstein@home将开始公开测试名为"Albert"的新计算程序,新程序能进行更为灵敏的搜寻。我们会先放出几百个新程序用的任务包,如果正常的话,我们将在接下来的几天分发更多的新任务包。如果用户碰到奇怪的问题,请至留言板的“问题与错误报告”版面寻求帮助。

May be it is the new test WU! ?

可能是吧,以前还没见过z1开头的wu,官方论坛上好像也还没什么相关的讨论

Bruce Allen关于新程序的说明:

- The new WU have different execution times, typically ranging from about 25% to 100% the previous execution times

- The new WU application incorporates all BOINC graphics and other bug fixes to date

- The new WU application has a slightly re-arranged screensaver, which includes our top wish-list item: a real time clock

主要就是任务包的计算时间变化较大

The new "Albert" search application seems to be working very well, so we are beginning to distribute thousands of "Albert" workunits. For more information, please see the this thread in the message boards. Happy holidays!!

新的'Albert'计算程序看起来工作很正常,因此我们已经开始分发更多的'Albert'任务包。详细信息请看留言板的这个主题。节日快乐!

1) We wouldn't have been lucky enough to get FLOPS counting this time around would we?

No, but I'll take a quick look at the API, and implement this if it's easy.

貌似这是BOINC提供的新技术,详细情况不了解

2) Are the improved run times from optimized compiles for windows?

The compilation process is no more and no less optimized than before. The differences in run times come about because we are now using a sky search grid and frequency band which depends upon frequency. This makes it impossible for all workunits to be the same length.

和原来的计算程序比较,没有更多/更少的优化,计算时间的变化来源于搜寻算法的改变

3) Is the Mac version still using Altiec?

Yes, the Mac version still uses Altivec optimization if the CPU supports the Altivec instruction set.

Mac版本仍然使用altiec优化

4) I got one running right now by the way (thanks), and it is hard to tell over RealVNC, but the graphics looks like they are a little "prettier". Estimated run time is ~3 hours so that looks like about 25% of the prior (though I am only 13% through).

If you have a real-time clock in the upper right hand corner of the screensaver/graphics screen and the wording in the corners has slightly cleaner layout, then yes, you are running 'Albert'.

版本的变化可以从屏保/图形的变化中看出来

5) Will we be switching back and forth between Einstein and Albert apps?

Yes, for some time now, until we are sure that the Albert app is working as required.

新旧程序将并存一段时间,直到albert达到需求

6) Does the Albert application have its own number (like 4.80) or is it still 4.79?

The Albert app has its own number and name. You will know you are running this by seeing what the name of the application is in the BOINC manager, or in the title bar of the graphics window. See the list of applications for more info.

新旧程序的版本号是不相干的(目前Windows版是4.37)

7) Is there any way we can download the new Albert application?

No. What work (and hence, what application) your computer gets is determined by chance. The 'scheduler' decides this when work is sent out.

是否下载新的计算程序及任务包是由调度程序随机决定的

昨天晚上收到了新的Albert程序
2005-12-26 22:22:55 [Einstein@Home] Started download of albert_4.37_windows_intelx86.exe
2005-12-26 22:22:55 [Einstein@Home] Started download of albert_4.37_windows_intelx86.pdb
2005-12-26 22:30:57 [Einstein@Home] Started download of skygrid_1090_r_T09.dat
但是还没有wu用该程序计算(可能下载时网络出了点意外…………),今天新装的一台直接就下了新了程序,明天开始运行,看看怎么样。
skygrid不知道是个什么东西?

Einstein@Home is now distributing an experimental application for Solaris (on SPARC). This has no graphics yet, but we hope to have a graphical version ready soon. Please report problems or success on this message board thread.

在SPARC/Solaris平台上分发了测试用的计算程序,并且不久后将在其中提供图形显示。请在留言板的这个主题下报告相关问题。

The Einstein@Home project now has more than 100,000 users with computing credit. But at the present rate, our current S4 search will take more than 200 days to complete, so please ask your friends and colleagues to sign up!

已经有超过10万的用户参与并为Einstein@home项目做出了贡献。但按照目前的计算速度,我们S4阶段的研究仍需要200多天才能完成,欢迎邀请你们的朋友和同事加入进来!

Due to a scripting error, some Einstein@Home users received an email message addressed to 'ballen' with a lengthy (repeated) 'how to opt-out of future emails' tail at the end. We apologize for this.

因为一个脚本错误,导致部分Einstein@Home用户收到了错误的电子邮件,我们为此深感抱歉。
