LHC@home

Hello community.

Since several weeks I'm having no tasks for LHC@home.
I thought it was because sometimes this project has no pending tasks.
But, after sometime seeing LHC not working, I dived into the web and saw that there's lots of tasks to download to my computer.
I have Asteroids@home running in BOINC (half time of CPU every project) and it runs fine and communicates with its server correctly.

Can anyone help me before desist to LHC@home?

Thank you

P.S. These are the last lines of the Event Log of BOINC

After this line, nothing happends at all

Maybe try to disable GPU work here https://lhcathome.cern.ch/lhcathome/prefs.php?subset=project There is no GPU work yet here but will maybe be there when xtrack is ready for it.
Not sure if that will change much but as long as there is no GPU work from LHC is it worth a try.
(CPU: job cache full; Intel GPU: ) this could indicate that it is looking to get work but you already have your job cache filled for the CPU maybe it is counting with Asteroids@home.

https://lhcathome.cern.ch/lhcathome/results.php?hostid=10827194 you did get work in the last days ATLAS Simulation (4) · CMS Simulation (8) · Theory Simulation (9) But they all failed instantly. The Virtual box tasks need a bit more love before they run. here is a guide what needs to be done for Atlas. https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=4161&postid=29359#29359

The easy workunits that run everywhere are sixtrack but they are still in development to be replaced by xtrack.So no workunits yet.

Thanks for your quick response.

It is quite disconcerting that only by unchecking the GPU option has everything started working again.

So, for the moment, it is unnecessary to make changes to VirtualBox.

If it fails, I will report.

Once again, thank you very much.

For CMS-tasks you may have to clean up Media with VirtualBox Manager.
Your last CMS-task got this:
Cannot close medium 'C:\ProgramData\BOINC\projects\lhcathome.cern.ch_lhcathome\CMS_2022_09_07_prod.vdi' because it has 1 child media

Maybe you have remnants of old stuck tasks.

Hi, Crystal Pellet.

I've already done; I did clear the virtual drive. As you said, I had and old task remaining and without ending.

Now, I'm waiting for new tasks to complete to see if the issue has been fixed.

Thanks a lot
