===> [runRivet] Wed May 11 07:14:58 UTC 2022 [boinc pp mb-inelastic 2760 - - sherpa 1.2.3 default 100000 254]

Ran ok till 22400 events then did nothing more for 12+hrs when I killed it. Full usage of a core but nothing actually being done.
I had another Sherpa 1.x.x a week or so ago that did similar.
I thought the early Sherpas were deprecated ages ago?

Have seen a Download of hours, Running Theory First time on Threadripper today in Win11pro!
Combination of Atlas AND Theory stopped Tasks for Theory, because of Tasklimit of 8. LHC-Prefs are set to nolimit.
Have deleted App-config for using Atlas. Now Download of Theory-Tasks is ok.

output.tgz with 17 Byte is not deleted in the Theory-SLOT-Folder after finishing a Theory Task.
Boinc is 7.16.11.
Have running Atlas and Theory as native in a CentOS8-VM.
Atlas have no problems, folder is empty after closing task.
When 400 Slots reached no more task is running neither Atlas not Theory.

<app>
<name>Theory</name>
<max_concurrent>40</max_concurrent>
</app>
Win11pro
Get only 20 Theory-Tasks.

Seeing .vdi with 2 GByte for Theory? (781 MByte in the most of the Theory-Tasks)

Setting environment...
grep: /etc/redhat-release: No such file or directory
seeing in all Theory Win11pro and Win10pro.

This Theory Tasks need some control from Cern-IT.

80 hour for nothing! 8 Tasks a 10 hour.

Several tasks have failed lately because Probing /cvmfs/... Failed! Unfortunately the task doesn't detect this and keeps on running although nothing happens in the VM anymore.

such a faulty task seen also yesterday.
bootstrap problem.
Computer ID 10795955
Laufzeit 15 Stunden 4 min. 20 sek.
CPU Zeit 2 min. 5 sek.

I don't run as many at the same time as before but I like these since we can check and see they are actually running in the log so that many hours are fine if they are really working.

funny Theory works fine on the same host that had problems last week with the CMS all of a sudden
And with that problem a clean install of VB newest and newest Boinc made no difference so maybe the latest Windows update so I may see if it needs a reinstall of the CMS vdi ....later

I'm having a problem with WUs not being downloaded due to "11/19/2023 8:40:03 AM | LHC@home | Not requesting tasks: don't need (CPU: ; NVIDIA GPU: )" even though I ask for "<project_max_concurrent>18</project_max_concurrent>" in app_config.xml, and have "use 100%" for both CPU # and CPU time. This is computer ASUS570 ID=10837826, 32GB, AMD 5950X. I get only one at a time when the previous WU ends. I only run Theory VBOX64 on this computer.

My other three computers are working fine and work is flowing. What else do I need to check?

have you different prefs?
home, school....

No. All are set to the same - home, school, work, default. There is something strange going on today, though. Only a few are actually making progress. The others are ... stalled? Of the 17 active on my A3900X1, only 3 are showing more than a fraction of a percent of a CPU time in my monitor. Those three are going 100% of a cpu each. Peculiar, but I have a meeting to run in a few minutes so I can't pursue just now. I haven't looked at the other computers yet.

Your tasks finish now. Was there an ISP problem?

Perhaps you looked at one of my other computers.

is the ONLY WU in process for the computer I can't get/keep more than 1 WU running. Please take another look, and I have had NO ISP problems. Thanks.

Set in your preferences Max # CPUs to No limit

ALL of my preferences have NO LIMIT for number of jobs and number of CPUs. My other computers are downloading and running 15-20 WUs each, so I know the preferences work.

I did a "diff" between this and another computer's app_config. They were identical except the other (running) computer did NOT have the entry, below:


<app>
<name>Theory</name>
</app>
<app_version>
<app_name>Theory</app_name>
<plan_class>vbox64_theory</plan_class>
<avg_ncpus>1.0</avg_ncpus>
</app_version>

After removing this, and having BOINC reload configs, I got 4 new tasks. Is this mis-coded in some way? I am curious!

After I posted yesterday, I saw that on your mentioned machine you sometimes had 2 tasks in progress for a very short period.
Another thing I noticed is, that the machine never had run BOINC benchmarks. You could try running the benchmarks to improve the situation.
Now the server has:

Measured floating point speed 1 billion ops/sec
Measured integer speed 1 billion ops/sec

Another machine of yours shows:

Measured floating point speed 4.6 billion ops/sec
Measured integer speed 18.89 billion ops/sec

I tried running the benchmarks, but it made no difference. Besides, another of my computers had not had the benchmarks run and it was processing just fine.

I did try another thing, though. I drained my (one) WU, cancelled a replacement that had started and reset the project. Then I removed app_config, adjusted the preferences to only 50% of the CPUs, and restarted. This worked so far, but I have NO idea why.

I plan to follow up on this approach to see what I can see.
