1) Questions and Answers : Unix/Linux : How is virtualization support determined? (Message 42614)
Posted 9 days ago by Profile Laurence
Post:
From the host details page, is looks like virtualization is detected. I think the issue is how it reports the platform.

x86_64-pc-freebsd vs x86_64-pc-linux-gnu

I have added a new platform for the Theory app. Please let me know if that works for you.

A failed execution of a Theory job does not fail the BOINC task. The output of the failed job is sent back to MCPlots and the job is not re-run. You can see the failed jobs in MCPlots.

Once again we are out of Theory Tasks.

There is an issue on the job submission side. I am investigating ...

Jobs are back.

Thanks. I forgot to updated the native version. Done now.

This new version will consider failed jobs as successful from a BOINC perspective. This means that the error output will be returned to the MCPlots server for further analysis and they will not be re-run on other hosts.
11) Message boards : Theory Application : 196 (0x000000C4) EXIT_DISK_LIMIT_EXCEEDED - how come? (Message 41248)
Posted 14 Jan 2020 by Profile Laurence
Post:
Three tasks in this workunit: https://lhcathome.cern.ch/lhcathome/workunit.php?wuid=130540238
1st EXIT_DISK_LIMIT_EXCEEDED https://lhcathome.cern.ch/lhcathome/result.php?resultid=259086785
2nd aborted by client https://lhcathome.cern.ch/lhcathome/result.php?resultid=259092479
3rd Valid cause I increased the rsc_disk_bound from 2000000000 to 8000000000 in my client_state.xml

Could an admin increase that setting for rsc_disk_bound server-side? It will increase the number of successes and avoid wasting CPU-cycles.

Done

Post:

My suggestion would be to calculate it based on <p_ncpus> which is already included in the client's scheduler request.


It was already limited to 2 tasks per p_npcpus but also had a maximum limit of 10. I have removed that maximum limit.

Post:
I thought nT was in production but it's limited to a fearful 10 WUs per rig. Because of the RAM-hungry ATLAS WUs I have to run ST to fill out my threads. I think BOINC runs best with fewer projects but stuck with running three now.

How many per rig should we increase it to?

The CMS problems have not been repaired yet so don't waste your time on them.
okay, I just thought that everything is okay now, since all went well for almost a week. But probably not so.
Perhaps Ivan could tell us more about the current situation.


Sorry this was my fault. I switched off a server that I thought we were no longer using and it looks like we are using it for the test. I have restarted it and will update the test.

I am wondering how they handle these in-house. Do they let them go forever? Probably not. In fact, I am wondering whether they do them at all. Maybe they just throw them over the wall to us. (Though not to me. I am out of Theory.)

In our internal batch system we have Job Flavours, job limits that are up to 1 week. Failures can be as scientifically valuable as success. See the Michelson–Morley experiment.

It also looks like VirtualBox is dropping support for 32bit hosts.
"Please also use version 5.2 if you still need support for 32-bit hosts, as this has been discontinued in 6.0. Version 5.2 will remain supported until July 2020."[/quote]

I have updated the scheduler. I hope it is an improvement over what we have now even though there is still a small issue. For those that are interested I have opened an issue in github.

Posted 26 Nov 2019 by Profile Laurence
Post:
As far as I understand the scheduler code, the issue is that the project preferences setting is limiting the ncpus and that this value is used to set the number of threads. We probably don't want to touch ncpus and just set the number of threads. Will switch over to the dev project to test out some changes.Those that want to join can see me there.

Is the Beta-Pref obsolet?

I haven't enabled this for ATLAS yet, am waiting for the green light.

It is now enabled.
