March 2, 2009 Testing in the future
We're in the process of debugging the test app. There will periodically be test WUs released in small batches to test the new app version. The new WUs should require lower accuracy and should complete more quickly than the last batch.

Credit will be given out for successfully completed WUs (that is, WUs without errors). However, we'd like to remind everybody that credit is not guaranteed for test WUs. Test WUs help us to release new versions of CAMB and keep C@H going; be aware, however, that these WUs can (and often do) fail, so if you would rather crunch regular WUs and not have to deal with the hassle of failed WUs, then disable test work in your project preferences. Crunching test WUs will never be compulsory. That being said, however, we will make every effort to reward users who donate their CPU time to help us test.

即将开始的测试

March 3, 2009 Test parameter file generator fixed
A problem which was causing the test parameter file generator to output empty parameter files has been corrected. I just tested a new test WU on my machine and it seems to be working file. I'll be creating another 500 WUs to test the app on other architectures. The credit for these WUs (excluding the 5 that I just made to test whether parameter file generation was working correctly) will be 3 times the normal amount.
好像是找到一些测试中的bug

March 8, 2009 Power outage on campus
There had been a power outage at the University of Illinois campus today for approximately 12 hours due to strong winds knocking down large power lines in the county. Due to this some of you may have experienced download problems from Cosmo@home over the course of the day but the power has now been restored and everything should be back to normal. If someone still experiences problems please let us know through the forums. Thank you.

The Cosmology@Home server died last week during a power outage. We're currently working to bring it back up. Sorry for the inconvenience!

When the server comes back up, we'll try to award credit to everybody who was unable to upload their WUs during the outage.

Cosmology@Home的服务器彻底挂了!他们正在努力恢复以前的备份!不过他们会尽力给因无法上传又超期的WU补偿应得的积分

[文々。新聞] 4月3日, 非官方新闻

上传服务已经恢复, 用户之前完成但无法上传的WU现在会自动上传并能被确认有效(前提结果要有效..), 积分会顺利给予, 不会因过期而作废..

但服务器其他功能仍未恢复, 无法发送新的WU..

预计需要熬过这周, 可能会在下周恢复正常..

2008年剩余新闻

December 10, 2008
Our new validator has completed its testing phase and is finally ready to go live! An important new feature of this validator is that it eliminates the need for homogenous redundancy and sets quorum of all WUs to 1. As with any major update there may be bugs so we request your help in identifying them. Thanks and Merry Christmas!

November 29, 2008
Once again, the ghosts in the machine attacked when everybody was out of town for Thanksgiving, rendering the server non-functional until someone could make it back in town. After replacing the network switch and the NIC, and applying a hefty dose of holy water to ward away any further geist attacks, the server is up again.

November 15, 2008
We have generated 50 test work units each worth 120 credits to test our new validator. The new validator essentially eliminates the need for homogenous redundancy and will also be used to organize our data more efficiently. Checking to see if these test work units download correctly will also help us narrow down possibilities and help find a solution to the HTTP errors many of you have been experiencing with this project.
-Anshul

October 18, 2008
Fixed a problem with the work generator and made approximately 10k new WUs. Sorry for the inconvenience.
-Scott

October 15, 2008
The WUs for the test application have been removed and we have started up the work generator. You should see regular WU traffic soon.

October 10, 2008
The old WUs are still around, since I made a mistake in the script used to cancel them, so I've just manually cancelled all of the old ones again. This shouldn't affect the new WUs at all.

October 10, 2008
Making some work today (for the main app) to test the new validation system. If the work starts to come back properly, then we'll start making more.

October 4, 2008
Anshul and I are going to spend the day working on the project. The first thing will be to clear out the WU queue and start from scratch. We'll keep you posted.

September 30, 2008
We've just hired a new administrator for Cosmology@Home, Anshul Kanakia. I will be working with him in the next couple of weeks to get the project up and running. Anshul is an undergraduate at the Univerisity of Illinois, so he will have as much time (or more) than I had in the past to dedicate to the project. Please welcome him and help him out if you can!

September 5, 2008
It should also be noted that test work will be validated regardless of whether or not it matches the partner WU. This will insure that nobody is penalized for running test work with the experimental HR.

September 5, 2008
After a little more work, we are going to release some work for the test app test_camb, which will be using a different (although not final) version of HR. The credit for these WUs will be higher than that for normal WUs (140 versus 120). If you want to participate in testing, please enable test work in your project preferences.

NOTE: This post has been edited to reflect the correct credit values.

September 3, 2008
The RAID array on our server broke down over the weekend, and after an incredibly-long recovery process, the server is back up.

August 29, 2008
The projct will be down while we work on the major problems facing the project right now, including work distribution, HR, and credit. We will be making work for a test application so we can test the new HR model.

August 9, 2008
Workunits created over two weeks ago have been piling up, so we've made a small change to the feeder code and cancelled the offending WUs.

July 31, 2008
The i686 Linux app issue has been fixed.

July 24, 2008
Due to a typo in the work-generation script and non-aggressive PHP error checking, work generation was down yesterday. It's been fixed now.

2009年新闻

Credit and Time Bound issues
2009年4月28日,AM 8:00:00
A total of 5000 credits have been added to profiles of all active Cosmo@home users. This is meant for expired/failed WUs due to project down-time and to compensate for the earlier low credit per WU payment for resource intensive CAMB 2.16 WUs. Also, the time bound for these new WUs has been incresaed from 10 days to 15 days which should be enough to complete crunching them even on machines ~5 years old.

Apps restored successfully and increase in credits
2009年4月18日,AM 8:00:00
We have restored CAMB 2.16 apps successfully for all platforms so all project specific errors (Signature and/or Checksum) should no longer be present. Also, most WUs for camb 2.16 are more resource heavy than the previous WU's for 2.15 so we have increased the credit for each WU from 140 to 200. If there are any disputes about this we will be happy to address them. If you feel that the credit being given for the 2.16 app, WUs is too little/ too much please start a thread related to this on the Wish List message board. Thank you.

More hardware maintenance
2009年3月27日,AM 8:00:00
After replacing a damaged RAID drive, the server kept throwing I/O errors and kernel panics, which required us to have the motherboard and RAID controller replaced as well. Hopefully this last round of hardware replacements will solve the problem and we will be back up today.

Website back up
2009年3月26日,AM 8:00:00
The website is mostly up and running at the moment. We'll have the project daemons up as soon as possible.

C@H down for server maintanence
2009年3月13日,AM 8:00:00
The Cosmology@home server has been suffering abnormal crashes ever few hours since the campus power outage on March 8, 2009. We will be taking to server offline soon for maintanence and repairs during which time Cosmolosy@home will not run. This website and the forums will also not be accessible at that time. We are working as fast as possible to get the project back up and running to its full potential.

Power outage on campus

Kevin implemented further fixes to the web site and the server software. The participant profiles can now be browsed through the web site. Spam profiles have been removed. Upload errors should have been cured. Please test and let us know what you find.

基本没人理这个项目是吧。。那我就只发最新的一条好了

2016-08-09: Cosmology@Home, Planck parameter sims paper out
普朗克参数模拟已出论文

In February we started running a new application. Today the paper making use of the results that thousands of you guys calculated is out! Look here in the coming weeks for more posts detailing exactly what we found. Until then, you can see the paper here. On behalf of the C@H team and of the Planck collaboration, thanks again everyone!

在今年二月的时候我们启启动了新的计算程序,今天,各位算友辛苦计算的成果正式新鲜出炉!在更详细的数据公布之前,您可以通过浏览论文一饱眼福:https://arxiv.org/pdf/1608.02487v1.pdf
