ATLAS native 2.91 was just released, which contains the improvements in v2.90, but with the problem with read-only tmp dirs fixed.

Please let us know if you see any problems!

First tasks are running with a local apptainer (from the Linux vendor).
So far there are no unexpected issues.

Since this ATLAS version is out there's a slow but steady increase of the average load values.
The more cores are given to ATLAS the steeper the load increases.
It looks like the cleanup doesn't work at the end of a task and some processes keep running.
Needs investigation.

The bad thing is that this will sooner or later lead to a crash.


After a reboot fresh ATLAS tasks create the following subfolders in the global tmp folders
in /tmp
hsperfdata_<boinc_username>

in /var/tmp
.cricinfo_<boinc_userid>

Can you see what processes are left running once a task finishes?

Unfortunately there are still some parts of ATLAS tasks hard-coded to use /var/tmp, we are working on fixing this. But I think /tmp/hsperfdata is something related to Java(?) and not coming from ATLAS tasks.

Just started an ATLAS task on a BOINC test instance.


My proxy log shows this, requested by that ATLAS task:
[06/Sep/2022:12:02:08 +0200] "CONNECT atlas-cric.cern.ch:443 HTTP/1.0" 200 1797516 "-" "-" TCP_TUNNEL:HIER_DIRECT


But I think /tmp/hsperfdata is something related to Java(?) and not coming from ATLAS tasks.

Right, it's from Java, but created during the start of ATLAS.


Will let the task finish to see what remains.

Have one test in CentOS9-VM:https://lhcathome.cern.ch/lhcathome/results.php?hostid=10813499
and seeing NO entry in \tmp or \var\tmp.

The test task finished without leaving anything weird.
Let's see what happens over night when the machines are back on full load.

Since today around 12:00 UTC I see a lot (not all) of Atlas-Native-Tasks fail after 600 seconds runtime.

You can check here: https://lhcathome.cern.ch/lhcathome/results.php?userid=555&offset=0&show_names=0&state=6&appid=


Supporting BOINC, a great concept !
