Downtime Explanation
Hi all, apologies for the extended downtime we had the past few days. We had a hard disk failure that, since it came over the weekend, took a bit longer to resolve than usual. We are back now and there was no data loss, however its possible some of your clients missed reporting deadlines (since we were unavailable). If you feel you lost significant credits because of this please don't hesitate to contact me. We're working on making sure similar errors in the future can be resolved quicker. For now, sorry again, and happy crunching! 13 Feb 2017, 11:53:22 UTC · Comment


Move Completed
And we're back! The server move to France appears to have gone well. We'll continue monitoring things closely to make sure the new machine is working well. Please let us know if you find any problems, and happy crunching! 15 Dec 2016, 9:11:33 UTC · Comment


C@H Move and Server Downtime
Tomorrow the C@H server is packing its bags and getting ready for a big move! After 10 great years of being hosted at the University of Illinois in Champaign-Urbana, we are moving overseas to Paris on a server at the Institut d'Astrophysique de Paris, where both myself and Ben are currently working. You can read more about this in an updated welcome letter from Ben.

At 2pm UTC on Wed Dec 14, we will take the server offline. The process may take up to 24hrs, during which your clients will still process pre-downloaded jobs, but will not be able to communicate with server. Upon finishing the move, you clients will reconnect automatically, and no actions from you are necessary. For the ultra-curious, I will try and post some live updates tomorrow on my twitter.

Server status
Hi guys, over the last several days the site has been suffering from what ultimately was a database error that caused several of the problems some of you have been posting / emailing about. Sorry for the slow response with the holidays here, but we should be fully back online at this point. Until everything is flushed out, there may be some workunits which will be screwed up as a result unfortunately. If you feel like you lost a significant amount of credit as a result of this, or if you notice anything still not working, please don't hesitate to PM me with more details. Happy crunching! 26 Nov 2016, 11:46:43 UTC · Comment


Some security and cosmetic upgades
We have added the option to access the C@H website more securely via "https", if you'd like to do so, you can update your bookmarks to use https://www.cosmologyathome.org. For now this remains purely optional (for example, if you don't know what https is, you can ignore this). At some point in the future, we will likely move to requiring this, but we'll give warning and post more details then.

Also, I've fixed a number of minor cosmic things about the site, most notably 1) the BBCode buttons when posting to the forums now work 2) a number of pages which were rendered too wide should now correctly fit the screen. If, as you're using the site, you find any other glitches, please don't hesitate to take a screenshot and post on the forums so we can fix things! Thanks all! (Edit: ha, oops meant to say *cosmetic* things above, although I'll leave in the somewhat appropriate typo)

Some technical behind-the-scenes at C@H
For anyone interested in the inner workings of C@H, you might be interested in this 10 minute screen cast I just posted. Its pretty technical, but shows what running a server and running jobs kind of looks like from our end. And of course if anyone with technical expertise wants to contribute to C@H with your code, not just your CPU cycles, we welcome that too!

LIGO Press Conference
Today at 10:30 EST there is a press conference from the LIGO collaboration. The rumors are that they will announce they have detected for the first time ever gravitational waves, in this case from the merger of two black holes! There are also rumors they will announce nothing because their policy is to insert fake signals into their data and not tell those doing the analysis until the very end (a so called "blind analysis"). Tune in to find out, this should be an exciting event! Check out here and here for two nice descriptions of gravitational waves of varying levels of technicality. 11 Feb 2016, 11:31:45 UTC · Comment


New beta app for analyzing Planck data
Today we are releasing a new app (in beta for the moment) to help analyze Planck data. Read more about it in the comments. Start crunching this app now for a chance to receive thanks in the acknowledgements of our forthcoming paper! 31 Jan 2016, 17:34:04 UTC · Comment


camb_boinc2docker no longer beta
As of right now the camb_boinc2docker application is no longer in beta, meaning everyone will receive these jobs by default unless they have specifically chosen not to.

We were down for the last ~24hrs due to some networking issues which are now fixed. We apologize for the inconvenience. 11 Dec 2015, 12:52:16 UTC · Comment


New app exiting beta status on Dec 3
On Dec 3 I will remove the beta status for the new app ("camb_boinc2docker") which means everyone who meets the system requirements will get the new jobs by default (currently only those of you who have selected "Run test applications" in your C@H preferences are getting them).

To ensure a smooth upgrade, please take a look at the requirements and FAQ. The most important things are having Virtualbox installed and enabling VT-x/AMD-v extensions. Thanks everyone!

CEO of Docker highlights Cosmology@Home
I just attended Dockercon Europe 2015, a huge tech conference for Docker, which is the software that powers the new camb_boinc2docker jobs. I also gave a talk about Cosmology@Home (which I will post a video of as soon as its available). But little did I know as I was listening to the keynote presentation along with a few thousand other attendees that Docker CEO Ben Golub would pick our project to showcase the types of things you can build with Docker. Needless to say I was floored and hugely honored! It was really cool, and thanks again to you guys for volunteering your resources to make Cosmology@Home possible!

Here's video of what he says (link should point to 23:12 right where he starts talking about it). I think he really nicely summed up what is exciting about C@H, and his description of the science we do was impressively spot on!

Credit and Time Bound issues
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 increased from 10 days to 15 days which should be enough to complete crunching them even on machines ~5 years old. 28 Apr 2009, 0:00:00 UTC · Comment


Apps restored successfully and increase in credits
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. 18 Apr 2009, 0:00:00 UTC · Comment


More hardware maintenance
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.

C@H down for server maintanence
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. 13 Mar 2009, 0:00:00 UTC · Comment


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. 8 Mar 2009, 0:00:00 UTC · Comment


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. 3 Mar 2009, 0:00:00 UTC · Comment


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.

New Validator to go online at midnight
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.

Server back up after Thanksgiving outage
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. 29 Nov 2008, 0:00:00 UTC · Comment


New Validator and HTTP error issues
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.

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! 30 Sep 2008, 0:00:00 UTC · Comment


Another note about test work
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. 5 Sep 2008, 0:00:00 UTC · Comment


Test work
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.

New CAMB, work generation, increased credit, and old WUs.
The new CAMB is now up and work generation has commenced; in addition, credit for the new WUs has been increased, since lensing is now re-enabled.

Although we let the old WUs drain as much as possible, there may yet still be some in the queue, which may cause some problems with the new CAMB. TTherefore, if you get work that is dated before the 22nd, you may want to play it safe and abort the WU.

New CAMB version and work generation later on today
We are nearly done with the new CAMB app with lensing, so it should be up later on today along with the new parameter generator. 22 Jul 2008, 0:00:00 UTC · Comment


WU validation and fixed CAMB application
The number of WUs awaiting validation is now under 2000, so we should be back in business soon. We've also fixed the lensing problem with CAMB, so we'll be releasing a new app version soon. Before that, however, we have to let the work queue drain a bit, so we'll be keeping the WU generator offline until the queue goes back to normal. 14 Jul 2008, 0:00:00 UTC · Comment

Another update
The project daemons seems to be mostly working at this point. There are still some problems with scheduling, though, and there are *far* too many WUs in the queue due to the population script not being able to get queries out in time, so we're going to wait a while to see if it settles.

So, until the validator and the other daemons are caught up on their work, we aren't going to send out any more WUs. We'll restart the scheduler as soon as it's done. Thank you for your patience. 2 Apr 2008, 0:00:00 UTC · Comment

Keep on Crunching!
Despite temporarily disabling the lensing component of CAMB, the results are still very useful to us, so please don't worry that your time here at Cosmology@Home is wasted. 26 Mar 2008, 0:00:00 UTC · Comment


Temporarily lowering credit from non-lensing CAMB WUs
Until we fix CAMB's lensing component, we will be temporarily lowering credit granted to all WUs from 100 to 80. 26 Mar 2008, 0:00:00 UTC · Comment


Canceling Old Workunits
It seems that the WUs in the queue right now will not run correctly, so we are going to cancel all of the current WUs and give credit to the WUs which have already been completed. Then, we will enable the new WU generator. Make sure to update your BOINC client so that you don't accidentally crunch WUs that have been canceled. 20 Mar 2008, 0:00:00 UTC · Comment


Project daemons back up and running
The project is now back up and running. The generator will be down for a bit until we run down the available WUs, but then the new generator will kick in. 19 Mar 2008, 0:00:00 UTC · Comment


Project Temporarily Suspended
We are suspending WU generation until the "Rombint" errors are solved and a new generator is up and running. 18 Mar 2008, 0:00:00 UTC · Comment

Permanent URL
Note that between today and tomorrow, the site URL might change between "www.cosmologyathome.org" and "cosmologyathome.org", although they are more or less equivalent. Tomorrow night, it should stay permanently at the former one. Sorry for any confusion this may cause. 24 Jan 2008, 0:00:00 UTC · Comment

On the coming Wednesday (1/23/2008), we will be performing some server maintenence at 5 PM CST (11 PM UTC). The server may be down for a period of a couple of hours, but I'll try to get it back up and running ASAP. 18 Jan 2008, 0:00:00 UTC · Comment
