Please read the readme file at github. It explains that the time shown in the script is absolute time from when the job was created in Boinc. If you would pause the job for 2 days it would show those days too. I leave all the CPU time calculations to Boinc.

The Atlas queue has been empty for a while now. There are still some resend tasks sent out every now and then. If you get one, the server seems to give you 24 hours to finish the task before it gets cancelled even if the deadline is still 7 days away. So keep your cache low and push the possible Atlas tasks to get them crunched asap.

the queue has run dry :-(

Is it known whether Theory_native is going to return at some point in the future, or has it been permanently retired?

Today I found two VirtualBox ATLAS tasks in a sort of zombie state with stderr containing:

The other log is similar.

Cleanup seems to have failed so I will abort both.

Other ATLAS tasks have been completing successfully on the same system. Does anyone have an explanation for this behavior?

Kernel 6.12.x loads a module that stops VB from starting. See this post for details.

You are correct that I experienced the same problem on a previous Ubuntu setup, however I didn't remember it.
I have implemented the workaround, and now my Atlas_native workunit is running correctly now.

Since this morning three CMS-Tasks are working.

I have had problem
VM Completion Message: glidein exited with return value 1.

Solution, in my case is changing network connection

Most of theory task take a very short time to be accomplished (less than a minute) and the Jobs chart show a high rate of failure (~60-70%). How to know if a task as due been completed ?

I encountered a compute error on an ATLAS native task that ran on my system for nearly two weeks before failing. Here's a summary of the failure:

Workunit: 231716588

Application version: ATLAS Simulation v3.01 (native_mt)

Client state: Compute error

Exit status: 195 (0x000000C3) EXIT_CHILD_FAILED

Host: ID 10873401

System: Linux Mint 22.1 (based on Ubuntu 22.04), CVMFS and Apptainer functional

Threads assigned: 5

Stderr shows this likely culprit:

mv: ‘ATLAS.root_0’ and ‘EVNT.44075481._002898.pool.root.1’ are the same file

This appears to crash the job early in its actual processing step, causing the wrapper to return an exit status of 195.

All CVMFS probes passed and the Apptainer container was loaded successfully from CVMFS. This seems to be an issue with the job script logic, likely in start_atlas.sh or its handling of the mv command near the start of execution.

Please let me know if you'd like additional logs or diagnostic output.

Thanks for all your hard work!

well, it seems that Sixtrack is no longer alive :-(

Waiting for XBoinc...

I will note that not all pythia8 tasks are failing. Very rarely do I get to sit down and look at what the VM is actually doing. But I've found some tasks give that error and some that don't.

CP5-CR2 is generating events
default-CD is generating events
default-noRap is generating events

qcdcr0 failed (by failed I mean they didn't generate any events)
tune-A2 failed I got 2 of them that failed.
tune-AU2 failed
tune-AU2lox failed
vincia-default failed (X2)
ropes failed

I haven't gotten any pythia6, sherpa or herwig tasks so I don't know about those.

Over 500 validate errors during the past couple of days.
Yeah, I had to set my boxes to "No New Tasks" so they waste electricity on the bad WU's

These lines confirm:
- that openhtc.io is used for CVMFS (good!)
- that your local proxy 192.168.1.125 is used (even better!)

This new version provides improved handling for configuring CVMFS proxies.

This happened to me as well but a project reset appears to have fixed it.

Thanks Laurence, however as of posting they have not been reinstated.

This will just cause confusion when 'B' appears again.

As it stands, there is already confusion, as the credits now shown on the leader-board do not add up to ones total credit (if the user ran sixtrack test and/or ATLAS long)
and if sixtrack test does appear again, would users credit start from 0 or from the previous score (assuming it is still in the database)? Transparency is needed in where credit is given to keep users faith in the credit scoring

OK that explains why that change happened

By reading the page you mention I don't understand if this BUDA thingy is "only for the server side of things" or also for the boinc client ? like we would not need VB anymore and boinc would run a packaged boinc application via docker on the participant machine ?
