Disk space limit decreased to 4GB

Atlas news - Fri, 06/24/2016 - 09:30
Hi all,

To make more effective use of volunteers running ramdisks we have reduced the disk space limit from 6.5GB to 4GB. See thread here

http://atlasathome.cern.ch/forum_thread.php?id=505

We see that most tasks use at most 2.2GB so this should be safe, but please notify us of any problems related to this change.[/url]

Scheduler and vbox update to detect 64-bit enabled computers

vLHCathome news - Tue, 06/21/2016 - 12:56
The BOINC scheduler has been updated to detect 64 bit machines that do not have the virtualization hardware extensions enabled. Also vboxwrapper has been updated for better error handling, and vboxwrapper 26193 is now deployed for Windows and Linux for the Theory application. This setup has been tested in our dev project.

Similar updates will follow later for other applications.

Many thanks to Rom Walton for providing these changes to the BOINC code.

CERN Summer Computing Challenge - SOFTWARE STOPPED

vLHCathome news - Tue, 06/14/2016 - 12:32
The software which supported the CERN Summer Computing Challenges in 2014 and 2015, and continued to run Theory jobs with minimum support, has now been halted due to lack of developer resources for this activity.

PLEASE DO NOT RUN CHALLENGE SOFTWARE UNTIL FURTHER NOTICE AS YOUR JOBS WILL BE LOST.

Many thanks to all Challenge volunteers who have contributed to this project and helped to explore new Web and CernVM technologies. We do have plans for a new WebAPI system for running multiple vLHC jobs inside a single multi-CPU VM and will announce this in due course.

LHCb beta application published

vLHCathome news - Mon, 06/13/2016 - 15:53
A new application to simulate Beauty physics at the LHC from the LHCb experiment has now been made available for those accepting beta applications.

Like the CMS application and the 64-bit version of the Theory simulations app, the Beauty simulations require a 64 bit computer with virtualization extensions (VT-x) enabled. Please refer to the instructions in the box on VT-x on the page: http://lhcathome.web.cern.ch/join-us for more information.

Specific discussions on the Beauty simulations can be done in the forum thread dedicated to the LHCb application.

vlHC Theory Application 64bit upgrade

vLHCathome news - Mon, 06/06/2016 - 11:15
We have put the new Theory 64bit Application into production today.

Please note the following important changes:

As it is a 64bit application, you must have VT-x / AMD-V acceleration enabled:
- To check this, in your VirtualBox Manager select "Settings -> System -> Acceleration" and make sure that "Enable VT-x/AMD-V" is activated. Also make sure another hypervisor isn't installed or running like KVM or Hyper-V.

For volunteers with 32bit hardware, the legacy 32bit Theory Application will be retained for a while:
- (subject to CoPilot continuing to run on a best-effort basis, as our CoPilot support person has just left CERN).

The CoPilot job scheduler system has been replaced by Condor:
- This enables us to unify both Theory and the LHC experiment applications going forward. (Condor is already implemented in the CMS Application here).

The VM consoles for the new Theory app are:
SCREEN 1: Boot console
SCREEN 2: Job output of running job
SCREEN 3: Linux "top" output
SCREEN 4: Job ID log (Condor and MCPlots)
SCREEN 5: Job error log
SCREEN 6: Login console

The web logs for the new Theory app are:
Parent (home) directory - the standard Test4Theory graphics with links to the other logs:
MasterLog: Condor Master process log
StartLog: Condor Start Daemon log
Starterlog: Condor Starter process log
running.log: Current executing job output file
.. finished_n.log: nth completed job output file
stderr.log: Job error log
stdout.log: Job ID log (Condor and MCPlots)

CMS Jobs Available Again

vLHCathome news - Sun, 06/05/2016 - 18:49
There was a fault with a server at CERN last night, which meant that we could not submit new CMS jobs, so we ran out.
However, the problem has now been fixed and CMS jobs are available again. Many thanks to the staff who worked Saturday night and Sunday to fix the problem.

WU running out shortly - more on Monday 6th

Atlas news - Sat, 06/04/2016 - 20:23
Hi all, just a heads up that we will likely run out of WU in the next few hours. We should get some more back in the system on Monday.

vLHC Theory Application 64bit upgrade (soon)

vLHCathome news - Mon, 05/30/2016 - 15:53
We plan to put the new Theory 64bit Application into production on June 6th. It has been tested for some time on our vLHC-dev site, and we think it is bug free. Please note the following important changes:

As it is a 64bit application, you must have VT-x / AMD-V acceleration enabled:
- To check this, in your VirtualBox Manager select "Settings -> System -> Acceleration" and make sure that "Enable VT-x/AMD-V" is activated. Also make sure another hypervisor isn't installed or running like KVM or Hyper-V.

For volunteers with 32bit hardware, the legacy 32bit Theory Application will be retained for a while:

The CoPilot job scheduler system has been replaced by Condor:
- This enables us to unify both Theory and the LHC experiment applications going forward. (Condor is already implemented in the CMS Application here).

More details will follow next Monday when the upgrade will take place.

Job output problems

vLHCathome news - Mon, 05/02/2016 - 11:33
Since 4pm yesterday, half of our job outputs are being blocked from returning to the MCPlots server. We are working to fix this problem and believe the outputs will be recovered correctly when it is solved.

Ageless: a decade of moderation

News of BOINC - Thu, 04/28/2016 - 20:27
As of today, Jorden van der Elst (AKA Ageless) has been moderating the BOINC message boards for 10 years! He's maintained order on the boards and has conveyed important posts to BOINC developers. We at BOINC are profoundly grateful for his dedicated and excellent work.

MCplots machine reconfiguring

vLHCathome news - Wed, 03/30/2016 - 17:42
Just got this message from Anton for all volunteers:

sorry for not letting you know in advance - I started the migration of mcplots machines to openstack service and pause jobs processing to speed up the migration. The copilot input queue have enough jobs to keep T4T busy for several days and output queue will be processed once the migration is finished - nothing will be lost. I think the migration will be finished in 1-2 days.

Cheers,
Anton

We will update the BOINC server software for vLHCathome this afternoon to bring it to the same level as for our development project.

The server will be down for an hour or so. Thanks for your understanding and collaboration.

Disk Space Exceeded

Sixtrack news - Wed, 03/16/2016 - 07:15
I am sorry we have submitted some "bad" WUs.
They are using too much disk space.
Please delete any WUS with names like
wjt-18-L1-trc......
wjt-15-L1-trc.......
Apologies.
