(LHC) CERN CMS-dev

[Gilthanis]

A bug has been found in the Windows version of BOINC which means that files larger than 4 GiB (2^32 bytes) are being left behind in slot directories, affecting us and other BOINC projects. Unfortunately, we do produce VM files that large, so we are interfering with these other projects. If you are active on this project, using Windows, please update your BOINC version to a patched version (see this message and thread).

"The files that are needed to apply the hotfix are

For 64-bit BOINC
boinc.080515.x64.zip

For 32-bit BOINC
boinc.080515.x86.zip

Simply extract the two files for your version from the .zip archive, and copy them to your BOINC program folder - you'll need to stop the BOINC client while you do this, and restart it again afterwards."

Thanks to the community for helping us debug this, especially Richard, Crystal Pellet and Ray, and to the BOINC crew for coming up with the fix.

In the meantime, we will move on to debugging why our VMs are currently growing so large.

Does this project still require an invite code to join?

As most of you already know, the aim of this project was to get the CMS application to a point where it was mature enough to be added to the vLHC@home project as a beta app. We believe that we have now reached that point and would like migrate our activity to that project.

The CMS beta application which should be identical to this one is now available in vLHC@home. Out of the 190 volunteers that have credit, 89% already have a vLHC@home account. Please could everyone who is running here try out the CMS beta application from vLHC@home. To do this you will need to go to the vLHCathome preferences and enable CMS Simulation.

If the beta app is working for you, please stop running here. Once most have migrated, no new tasks will be created and the accumulated credit can be migrated from here to vLHC@home.

Please post any comments or issues relating to the migration in this thread.

Thanks to everyone who has supported this project and enabled us to get to where we are today.

As mentioned earlier (under "Project Restructuring"), CMS-dev has evolved into a more general dev project for virtual machine applications running under LHC@home.

We will therefore rename the "CMS-dev" project to "vLHCathome-dev" as it is now a development project for early testing of applications that potentially could run in production under the Virtual LHC@home platform.

The change is planned for tomorrow 13 UTC, and you should later see this project as:
CMS-dev

Redirection will be put in place, so in principle BOINC clients should be able to follow. Otherwise please detach the project and re-attach to the new URL at your convenience.

Thanks to your contributions and feedback on tests of our applications, CMS-dev has been a success, and we would like to express our warm thanks for your contributions!

Please note that this remains a development and test project, that might provide unstable applications and that any BOINC credit accumulated here might get lost.

If you prefer to just crunch and get credit, please give priority to our production LHC@home projects.

Many thanks for your collaboration!

Change of project name

It appears that vLHC-dev now does beta work for LHC six track and may not require virtualbox to run it. However, if you want to run those work units exclusively, you will need to change your project preferences from with in your account at the website.

Finally hit my 1 million point goal. Moving on.
