Upload server

Atlas news - Fri, 05/22/2015 - 14:10
Dear All,

In the past few days there were some load issues with the upload server and therefore it took some time for tasks to upload the results.

We handled this and it's working fine now.

Quorom of 5, wzero and Pentathlon

Sixtrack news - Sun, 05/17/2015 - 16:32
I am currently running a set of very important tests to try and
find the cause of a few numerical differences between different platforms
and executables. I could/would not do this usually but because of your efforts
during the Pentathlon I have a unique opportunity. Also keeps up the
workload and gives you all an opportunity to get credits.
These test are wzero with a quorum of 5.Thanks. Eric.

Please note that this may occur if you are also subscribed
to the LHC experiment projects ATLAS or CMS using vLHCathome.
A workround is to delete the remaining files yourself.

News 15th May, 2015

Sixtrack news - Fri, 05/15/2015 - 22:34
As many of you know LHC@home has been selected to host
the Sprint event of the BOINC Pentathlon organised by
Seti.Germany. Information can be found at
The event starts at midnight and will last for three days.

This is rather exciting for us and will be a real test of
our BOINC server setup at CERN. Although this is the weekend
following Ascension my colleagues are making a big effort to
submit lots of work, and I am seeing a new record number of active WUs
every time I look. The latest number was over 270,000 and the Sprint
has not yet officially started.

We have done our best to be ready without making any last minute changes
and while this should be fun I must confess to being rather worried
about our infrastructure. We shall see.

We still have our problems, for a year now.

I am having great difficulties building new executables since Windows XP
was deprecated and I am now tring to switch to gfortran on Cygwin.
It would seem to be appropriate to use the free compiler on our
volunteer project.

We are seeing too many null/empty result files. While an empty result can
be valid if the initial conditions for tracking are invalid, I am hoping
to treat these results as invalid. These errors are making it extremely
difficult for me to track down the few real validated but wrong results.
I have seen at least one case where a segment violation occurred, a clear
error, but an empty result was returned. The problem does not seem to
be OS or hardware or case dependent.

I am also working on cleaning the database of ancient WUs. We had not
properly deprecated old versions of executables until very recently.

I am currently using boinctest/sixtracktest to try a SixTrack which will return the full results giving more functionality and also allowing a case to be automatically handled as a series of subcases.

Then we must finally get back MacOS executables, AVX support, etc

Still an enormous amount of production is being carried out successfully
thanks to your support.

I shall say no more until we see how it goes for the next three days. Eric.

New beta app: Theory simulations using DataBridge

vLHCathome news - Thu, 05/07/2015 - 14:44
A new version of the Theory simulations application is now available for users that allow test applications. The simulations running in the VM are similar to those in the regular Theory application, however the queue and job management to the VM is handled via the "Data Bridge" application layer that is a new and more flexible framework that is intended to replace the CoPilot application layer that has been used up to now.

Happy crunching!

CoPilot server upgrade

vLHCathome news - Mon, 04/27/2015 - 15:27
We are about to upgrade our CoPilot servers, which interface all volunteer VM's with our MCPlots server - the source of the jobs and the science behind this project. We hope you will not notice this - it may cause a few lost jobs but should not affect any BOINC tasks. A news update will follow after the upgrade.

Vboxwrapper upgrade to latest version v261.66 (all systems)

vLHCathome news - Wed, 04/15/2015 - 14:57
We have just upgraded to vboxwrapper v261.66 for all BOINC T4T clients (Windows, Linux and Mac).

Please let us know if any problems occur, preferably by posting to this News thread.

Note that starting with this release snapshots will no longer be used: VM's will be Saved rather than PoweredOff when BOINC suspends or restarts, which avoids losing or repeating some jobs or events.
*** For the moment, it may be necessary to reset the vLHC project to enable this feature ***

Survey from Argentine startup

News of BOINC - Wed, 04/15/2015 - 02:46
I saw this ( in my BOINC feed and it looks to be all hype and no substance.
Just a different form of BOINC and I see no added value to it.

That particular thread simply says it's looking for beta testers, and not anything about the "test".
The Google-doc the link in the OP thread points to ( doesn't give any more information regarding their "concept".

Their two youtube videos also give very little information and simply tries to hype their app.

Knowing they say their project is based on BOINC and considering you are reading this, you probably already have BOINC.
And I think of BOINC as an open project (source available) and one I can trust.

I see NO added value in Alantu's test/concept/whatever while BOINC is already established and working.

I question the motive with Alantu's project. Will it be mining bitcoins on one of the processors? Will it be including ads to generate revenue?

BOINC: For the sake of science, not corporate/political/money.

Problem with CERN server resolved

vLHCathome news - Sat, 04/04/2015 - 11:17
Well, in spite of it being Easter Saturday, the support team did identify the failing server machine and the problem is fixed. Particular thanks to Pete Jones (in Geneva) and Artem Harutyunyan (in California !!).

Happy holidays again to all.

Problem with CERN server

vLHCathome news - Sat, 04/04/2015 - 07:34
Since 8pm yesterday there is a problem with part of the CERN server infrastructure for vLHC@home, which prevents jobs being fetched or returned to the VM's. As CERN is closed for the Easter holidays, this may not get resolved until Tuesday April 7th. In any case we wish all our volunteers a happy holiday break!

Server maintenance today

Atlas news - Wed, 04/01/2015 - 08:48
Dear volunteers,

we are migrating part of server infrastructure today, which will take few hours. In the meantime there might be a lack of workunits to send and the boinc server will be unavailable for an hour or so. We will let you know when the maintenance is over.
