Message 7948 - Posted: 13 Mar 2023, 11:26:28 UTC

I've started submitting tasks with the Run 3 software now - these are tasks with input file EVNT.29838250._000010.pool.root.1.

Please post if you see any problems or notice anything strange, for example in the event monitor or other places.

Looks like native tasks run well now, but I'm still ironing out a few issues with the vbox version.

Sorry, but for me, it looks very unusual . These 2 tasks seemed to run endless, CPU-Time was way to low:



I'm running Ubuntu 22.04.x

Oh, I see, results have got uploaded now, both say "Hits file was produced successfull": Not shure, if this is really true

The tasks are successful, but the run time is quite large compared to the CPU time. These are short tasks simulating 5 events each, I will submit some longer ones with 50 events to see the difference.

I think the vbox tasks are also working ok now.

Findings:

1.
On a fully loaded Threadripper it takes ~20 min to complete the initial setup.
This is mainly caused by lots of downloads from CVMFS and Frontier.
The long setup phase has already been mentioned by other testers.


2.
Frontier requests are sent to atlasfrontier-ai.cern.ch although they should go to atlascern-frontier.openhtc.io


3.
Looks like worker threads do not log their progress into separate logfiles any more.
This means ATLAS event monitoring (vbox app) will not work any more.

Atlas Event Progress Monitoring(v.4.1.0) show 500 events total, but no other details.

A long setup time would be expected for the first native task, since the CVMFS cache needs to be filled with the new software libraries. I'd be interested to see the timing for subsequent tasks on the same host. On my test host running native tasks (inside CERN, so ideal conditions) and a warm cache it takes around 5 mins to start crunching.

2.
Frontier requests are sent to atlasfrontier-ai.cern.ch although they should go to atlascern-frontier.openhtc.io


Right, this is an error on my part, I will fix it.

3.

This is a feature of the way the new software works. Instead of multiple processes, it uses multiple threads which makes memory usage much more efficient. (background reading for anyone interested)

This means all the threads log to a single file, log.EVNTtoHITS, which is how single core tasks worked before. I suppose the monitoring worked for single core tasks in the past so it should still work now?

To test this and ensure comparable total load I'll run another task when the 1st one has finished.

Monitoring needs to be revised.
The old ATLAS version wrote it's log information into a couple of files.
In case of a singlecore setup only "log.EVNTtoHITS" was used.
In case of multicore "log.EVNTtoHITS" was used for global information like the #events but the event status was logged to the worker logs.

Now its all in "log.EVNTtoHITS" but the output patterns are not consistent, e.g.:
11:18:13 ISF_Kernel_FullG4MT_QS.ISF_LongLivedGeant4Tool       108     2    INFO 	 Run:Event 410000:99609	 (29th event for this worker) took 239.9 s. New average 450.6 +- 44.52
.
.
.

I can not confirm this expected behaviour.

First: Remember, I have set up a central Squid-Proxy that works fine.

You can check all my active clients, they are all running one DEV-Task after another. So, I would expect that the second or third Task would need less startup time, but they all need the same time.

Example: https://lhcathomedev.cern.ch/lhcathome-dev/results.php?hostid=4703

In the log-file I see still these warnings:
