Thanks for the tip watching the runRivet.log. That's a reasonable solution.

Hello,

i have a Theory native task (pythia8) which is running for nearly 3 days now.
The longest job of about the last 100 jobs ran for 13 hours.
How can i check if a native task is still doing what it's magic or if it's stalled?

BTW: How long does a native task run before it aborts itself?

Thanks and regards!

On one of my machines i will try to run ATLAS native with a locally installed singularity, to see if this helps.

No, unfortunately even with a locally installed singularity ATLAS native doesn't work.

https://lhcathome.cern.ch/lhcathome/result.php?resultid=312206373

The error in the logfile shouldn't occur because the user is member of both groups "boinc" and "singularity" and therefore should have all permissions needed.


The feedback I got said there was a configuration change related to setuid in the latest singularity, and he pointed me to this page. However from your last sentence it seems you have already done what is suggested there, so I'm not really sure what to do.

That was the one machine i equipped with a local installation of singularity, and yes, i have done what the readme file was suggesting. Strange, that it doesn't work anyway...

But what about my initial problem on the machine without locally installed singularity?
I tried one more task today and still have the same problem.

https://lhcathome.cern.ch/lhcathome/result.php?resultid=312621601

Had the singularity expert something to say about that particular problem?

Thanks and regards!

Yes, those are tasks from BEFORE the singularity update David mentioned.
All tasks AFTER this update are failing.

No, i'm not using condor. The directory /var/lib/condor doesn't even exist on my machines.

This would explain the sudden problem of creating the singularity container on my machines.
I don't have singularity installed locally, so my machines use the CVMFS version, which was updated and don't seem to work with my machines. So i guess the simplest solution is to install singularity locally...

Since a few minutes ago i have the following error on ALL of my ATLAS native tasks:

FATAL: container creation failed: hook function for tag prelayer returns error: failed to create /var/lib/condor directory: mkdir /var/lib/condor: permission denied

Since this is just since today and on more than one machine, i don't think this a local problem!? I didn't change anything on my machines which were working flawlessly for months.

Oh wait...there was an update for my OS today...unfortunately i do not remember the package which was updated. I hope this is not the problem...

Anyone else with this problem? Any hints?

9) Message boards : ATLAS application : credits for runtime, not for cputime ? (Message 44654)
Posted 4 Apr 2021 by djoser
Post:
I have step out until there have been some re-work on this and would like admins to take a look on this and project could be greylisted until it has been fixed

I think there will be no re-work of this matter ever. Here is why:

First of all the amount of work done by BOINC-Users is just a small fraction of all work being done by WLCG internally (although it's said to be compareable to a TIER-2 site). I think they just keep up the infrastrucure for BOINC because it's free computing power to do simulations. And BOINC-Crunchers do nothing else but simulations for CERN (besides Sixtrack).

Secondly the credit issue just affects Gridcoin participants, which again are only a small fraction of BOINC-Crunchers. Normal BOINC-Crunchers don't really care about credits.

So why should they waste time (and therefore money) to fix something that only matters to a few cryptocurrency nerds? Don't get me wrong, i'm one of those nerds, but even i think this matter is not really important. I'm in for the science, not for the Gridcoins!

Just paste the URL in the BOINC address field:
https://lhcathomedev.cern.ch/lhcathome-dev/

I tried that and BOINC Manager displayed a message that only already registered accounts can connect to that project. So you need to register on the website first and to do so you need an invitation code. This was established in 2018 to avoid spammers.

I am going to test the long tasks on the LHC-dev project first, so if any of you want to try it please head over there and select "ATLAS very long simulation" from the app list.

I would like to try it out, but -dev is invitation only.
Since i'm not a developer or project admin, i guess i'm not wanted over there!?

Yes, but it is not in the applications list yet.
So no information about native, vbox or both...

I am going to create a separate beta app for the long tasks which people can choose to run if they want. I'll let everyone know via the message boards when there is something ready to test.


Will this be a native-App, or will it be vbox?

Is it that the Atlas native app is not using the same library / commands than the theory one ?


No, they don't. For instance: Theory uses 'runc' containers, ATLAS uses 'singularity' containers.

It is not possible to pause ATLAS tasks. One task runs 200 events. If it is interrupted and resumed it will restart at zero.

Looking at the Stderr logs of your failed Theory tasks show this lines:

VBoxManage.exe: error: VT-x is disabled in the BIOS for all CPU modes

Please check if VT-x is enabled in BIOS on that machine.
