In this case it looks like the error is caused by a local setting.
Unfortunately the SixTrack queue is empty atm.
You may...

- shut down the BOINC client
- check the file and directory permissions of the BOINC tree
- test whether the BOINC user account can (manually) create a folder directly below /slots/ (e.g. /slots/blibla)
- from that folder run (manually) "../../projects/lhcathome.cern.ch_lhcathome/sixtrack_lin64_50205_avx.linux"
- does it create a "stderr.txt" beside a couple of other files?

Post your findings here.
The test folder can then be removed and BOINC can be restarted.

If you run other projects beside LHC@home, do their tasks succeed?


Thanks, my applogies for the late reply.

I think everything seems to be alright with the permissions.

Creating the directory test:

drwxrwx--x 2 boinc boinc 24576 Nov  8 18:50 0
drwxrwx--x 2 boinc boinc 28672 Nov  8 18:50 1
drwxrwx--x 2 boinc boinc 28672 Nov  8 18:50 10
drwxrwx--x 2 boinc boinc 24576 Nov  8 18:50 11
drwxrwx--x 2 boinc boinc 28672 Nov  8 18:50 2
drwxrwx--x 2 boinc boinc 28672 Nov  8 18:50 3
drwxrwx--x 2 boinc boinc 28672 Nov  8 18:50 4
drwxrwx--x 2 boinc boinc 28672 Nov  8 18:50 5
drwxrwx--x 2 boinc boinc 24576 Nov  8 18:50 6
drwxrwx--x 2 boinc boinc 28672 Nov  8 18:50 7
drwxrwx--x 2 boinc boinc 28672 Nov  8 18:50 8
drwxrwx--x 2 boinc boinc 24576 Nov  8 18:50 9
drwxrwxr-x 2 boinc boinc  4096 Nov  8 19:03 test


Running command sudo -H -u boinc ../../projects/lhcathome.cern.ch_lhcathome/sixtrack_lin64_50205_avx.linux creates the following output in that test directory:

-rw-rw-r-- 1 boinc boinc    0 Nov  8 19:03 boinc_lockfile
-rw-rw-r-- 1 boinc boinc 1504 Nov  8 19:03 file_units.log
-rw-rw-r-- 1 boinc boinc    0 Nov  8 19:03 fort.91
-rw-rw-r-- 1 boinc boinc   31 Nov  8 19:03 fort.92
-rw-rw-r-- 1 boinc boinc   41 Nov  8 19:03 fort.93
-rw-rw-r-- 1 boinc boinc  113 Nov  8 19:03 sim_meta.dat
-rw-rw-r-- 1 boinc boinc  217 Nov  8 19:03 sim_time.dat
-rw-rw-r-- 1 boinc boinc  211 Nov  8 19:03 stderr.txt



Anything else I can try?

Thanks

Hi,

For the second time in several weeks I got a whole batch of tasks which have been reported as invalid (calculation error) when started.
Anyone else experiencing that?

Client: Unbuntu Linux 22.04.1 LTS

Anyone else experiencing this? Or anyone knows about the problem?

Thanks
Heinz
