LHC@home

Hello,

I've been doing LHC@home tasks for the past 2 years.
Recently though I have been getting no tasks from the scheduler ( for any LHC projects.)

I'm currently running Rosetta tasks and seti tasks without problems.

I've tried to reset project and updated preference and settings but to no avail.(No project data was re-downloaded after project reset.

Could someone look into why am I not receiving tasks since there are 2000+ ready to send?

-Edit1-
Passed trough Yeti's checklist.
Checked all stuff except docker, which is disabled and Hyper-V is off.

Thank you!

Your Windows machine has just finished two sixtrack tasks. They finished very fast (in about 6 seconds) but so did you wing mate who did those tasks too. So the tasks were just very short in nature and not a problem in your computer.

If you look at the server status page (link on left side of the page) you can see that there aren't any new sixtrack tasks available currently and even when there are any, they will be gone in a heartbeat, especially because some of the tasks are so short.

Yes, I saw that but still there are 1778 ATLAS Tasks ready to send and I am getting none.

I am subscribed to all task types.

Did you just recently add Rosetta and SETI? In that case, the BOINC scheduler will prefer them until you reach the percentage specified in the "resource share" for each project. It can take several weeks to stabilize.

To speed that up to a day or two, I place the following cc_config.xml file in the BOINC Data folder:

<cc_config>
<options>
<rec_half_life_days>1.000000</rec_half_life_days>
</options>
</cc_config>

You can just create it as a text file in Notepad for example, but then use "save as" to save it as an ".xml" file (not as a text file).

if jim's advice doesnt change anything, please post your boinc logs here, maybe its easier to help then.

btw: your boinc client is connected to the new lhc@home site "https://lhcathome.cern.ch/lhcathome/" isnt it?

Log when I hit update.

Yes gyllic it connects to that URL.

Yes Jim I added those xml lines to the new file.

So far no improvements, and apparently only LHC tasks are affected by this.

Update

I was able to get tasks working on my linux laptop with the same boinc settings so I hope it will work good enough to get me to 50.000 credits.

It's weird what my windows machine does but it will get solved sometime too.

Bogdan,

take a look in Yeti's Checklist in the Atlas message folder.
This is very useful for the beginning with Atlas.

God damn it works.

Did you try to crunch Projects using VMs in the past while VT-X / AMD-V / VIA-VT was not enabled? Could be that BOINC has kept this in mind!

To check and fix this, first exit BOINC and make sure, all BOINC-Tasks have really finished.

In your BOINC_Data-Directory you will find a client_state.xml. Open this with a simple editor and search for:

<p_vm_extensions_disabled>1</p_vm_extensions_disabled>

If this is absent or the number is 0 / zero than all is fine. Otherwise change it to 0 / zero <p_vm_extensions_disabled>0</p_vm_extensions_disabled> and safe the file. Be carefull to save it as a real ascii-file

Be carefull that you closed your BOINC-Client successfully before you change anything in client_state.xml. Otherwise BOINC will overwrite your changes.

But thing is this could have happened in the BIOS reset I did.
Interesting thing.

Thank you all for the ideas.
