Dear all, due to a scheduled power outage at our hosting site, Cosmology@Home will be offline starting later today (Dec 13) and may remain down for as long as 48hrs. We apologize for any inconvenience.

Posted 6 Dec 2017 by Profile Marius
Hi guys, I've added a new version of camb_boinc2docker, version 2.05 and marked as beta (so you'll need to enable beta testing apps in your user preferences to get these jobs). This uses the latest version of vboxwrapper. I'm curious if this solves any of the problems people are seeing with the newer versions of Virtualbox?

Hi Clark, I'm not entirely sure, nominally I thought indeed boinc2docker wouldn't support 5.2 until I can upgrade it to the latest vboxwrapper, which I plan to do soon but haven't had the time to. Nevertheless, plenty of people in the database are running these jobs apparently fine with 5.2. I can try and get to the update over the weekend and we'll see if hopefully that fixes it for you (and possibly others).

Posted 27 Nov 2017 by Profile Marius
What settings do you have as your BOINC computing preferences? Some of these are applied to the VM in the form of VBox execution caps, so it could be coming from there.

Posted 16 Nov 2017 by Profile Marius
Hi everyone, graduate student Lo Lee and Professor Peter Darch of the University of Illinois (where we got our start back in 2007) are conducting a survey of Cosmology@Home users for their research. If you have a moment, we'd appreciate if you could fill in the survey at https://illinois.edu/sb/sec/2695704. Your (completely anonymous and confidential) responses may also help us guide the design of Cosmology@Home in the future. Many thanks!

Why won't they answer the question on why their remaining times are increasing rather than decreasing?


Hi Paulie,

Apologies I haven't responded sooner. The problem is that camb_legacy is so old its barely supported, and I'm really not sure what's going on in your case. I should have at least let you know I had read your message, just that I don't have a solution, sorry. A more long term solution is to look into running the camb_boinc2docker app if you are able to do so.

Posted 16 Oct 2017 by Profile Marius
I am wondering if you are actually getting the errors and then just getting the same work units right back


Yea, this is plausible. When a task is aborted it gets resent to a different user, but that could just randomly have been you again. I'd suspect something is wrong only if this is happening a lot (is it?)

Posted 8 Oct 2017 by Profile Marius
Hi guys, sorry about this, indeed this has been an ongoing issue. Its fixed again for now but I'll look into a more permanent solution, which probably involves buying a better hard disk for the server, since that's what's lagging causing the validation to go really slowly.

Posted 7 Sep 2017 by Profile Marius
The validator did have a hiccup around then but should be fixed now. Are you guys still seeing many bad WUs?

EDIT: Ah no sorry, I think I see what the problem still was. It should be fixed now.

13) Message boards : News : cosmologyathome.org downtime explanation (Message 21495)
Posted 18 Aug 2017 by Profile Marius
Hi all. As you might have noticed, cosmologyathome.org was unreachable for the last ~2.5 days. This was due to a failure properly reregistering our domain name after moving the server from one university to another earlier this year. In addition, as we couldn't contact you via the website, we tried to send out email notification of the issue, but due to a problem with the server software many of you did not receive this email. We'll work on addressing this so in the future it doesn't happen again. All should be back to normal now, although it may take as long as another 24 hours for the domain to fully propagate everywhere. We greatly apologize for this extended down time.

This temporary URL is only meant for the website and forums, connecting BOINC clients to this URL will not result in receiving any new jobs.

Posted 16 Aug 2017 by Profile Marius
Hi folks. Due to a mix-up related to having moved servers from one university to another earlier this year, we failed to properly renew the cosmologyathome.org domain, which expired today. We are in the process of seeing what can be done to fix this. Until then, you can access the website at the temporary URL you are currently at, https://cosmos.iap.fr, and I will post the latest news on the situation here. We apologize for this downtime.

This is actually one of my own most desired features, but unfortunately C@H doesn't have the man-power to implement it. Perhaps enough interest could be generated so that it becomes a part of BOINC itself though.

Posted 18 Jul 2017 by Profile Marius
Hi guys, many apologies, I've been busy with other work and was only today able to take a look at this issue. I've now fixed a minor database hiccup but which had lead to the big backlog of validation you saw. That should now be fixed, and the validation queue should now be shrinking. It may take a day or so until it is all caught up but everyone should eventually receive their earned credit.

Will the docker app be resumed now that the pentathlon is over?

Yes, I'll add more jobs soon as we finish the batch of Planck jobs sitting in the queue.

The BOINC Pentathlon is complete, as is our own Planck contest! You can see the results of the Planck contest here and of the Pentathlon here. Congratulations to users Mumps[MM], UofS-Computer-Science, and Bryan, and to team SETI.USA (who also won the Pentathlon)! You guys will be added to the list of thank-yous in our paper.

In the end it was a quite exciting race for the 3rd place user spot, Bryan managed to overtake KaptainBlaZzed with only 45 minutes left in the contest last night! Well done to both of you and many thanks to all of the thousands of users and hundreds of teams that contributed. This was far and away the most computing power I've seen at C@H since I've been managing it, and the workunits you computed will greatly help us improve our work. Stay tuned for a future post about these results.
20) Message boards : Technical Support : Communication with VM Hypervisor failed. (Message 21432)
Posted 11 May 2017 by Profile Marius
Until now, my boinc-client was started as boinc user
Despite being member of vboxusers group, boinc user did not manage to communicate with virtualbox... maybe because it has not got any personnal directory where to store its virtual machines ?
# sudo -u boinc VBoxManage -q --version
5.1.22r115126
# sudo -u boinc VBoxManage -q list systemproperties
VBoxManage: error: Failed to initialize COM! (hrc=NS_ERROR_FAILURE)
# sudo -u boinc VBoxManage -q list hostinfo
VBoxManage: error: Failed to initialize COM! (hrc=NS_ERROR_FAILURE)

As I don't know how to handle this problem, I decided do change the user running boinc, it's now the same user as the user running my graphical session.
systemctl stop boinc-client
In /usr/lib/systemd/system/boinc-client.service
set in [Service]
User=myusername

Then change rights on BOINC directory, boinc logs, and remove lock file
chown -Rf myusername. /home/myusername/BOINC/
/bin/rm -f /var/lib/boinc/lockfile
chmod g+w /var/log/boinc.log
chmod g+w /var/log/boincerr.log

(myusername is member of boinc group)
End with
systemctl daemon-reload
systemctl start boinc-client.service

Now my camb_boinc2docker are running fine. And I can see them in VirtualBox.
This looks as a solution. Maybe you do think others are possible.


Sorry I missed this message earlier. This is really quite interesting and another angle to solving this problem (which unfortunately quite a number of people have) that I had not considered until now. Let me take a look to see if I can reproduce the issue on my computer by switching users and get back to you.
