I just had a 2-core ATLAS task the total runtime of which was 493,73 seconds, CPU time 173,11 seconds, yielding 3,95 credit points.
Never ever before I saw such a short ATLAS task - is this a new series now?

David, are you aware of it?

thanks for your efforts - I didn't even bother to look up the stderr, since the task got finished successfully.

successful for boinc standards, not successfull for atlas standards, since there is no HITS file

yes, unfortunately :-(

I noticed a few of failures like this in the new batch of tasks - "EVNTtoHITS got a SIGSEGV signal" means a crash of the ATLAS code so nothing you can do about it I'm afraid.

We still give credits for these kind of failures so we don't punish volunteers for problems in the ATLAS code, but as gyllic said, no HITS file means it was unsuccessful for ATLAS.

Ths same thing happens to me on my Windows 10 PC, Atlas tasks complete and validate in a very short time but no HITS file..

The recent ATLAS batch works on a large input file (>300MB).
This may be a bit too large for your local configuration.

You may try to increase the RAM setting for your VMs by a few 100 MB to 4600-4800 MB.
The relevant setting is located in your app_config.xml.

Hope this will be successful.

again I had an ATLAS task with runtime of about 10 minutes:

You may consider to stop your BOINC client, clean the VirtualBox environment and do a project reset before you start a fresh task.

Single core Atlas tasks on my slower Linux laptop complete with Hits file. Double core tasks on the Windows 10 PC complete in short times with no Hits file.

Is it this statement that indicates success?

... Is it this statement that indicates success?
2018-04-11 01:37:31 (7056): Guest Log: Successfully finished the ATLAS job!

It depends on the perspective.
"Guest Log: Successfully finished the ATLAS job!" indicates a successful end of the BOINC task and your host will most likely get credits.

From the science perspective a file like "HITS.*" contains the results and should be included in the upload.
This name normally appears in the directory listing that is included in the stderr.txt and can be checked there.

Thanks! Found it noted in 4 places, including twice here:

Does one of the experts know why this task was unsuccessfull: ...

for me, the key-words are "No events to process" - so, maybe, the task was somehow mis-configured

... so, maybe, the task was somehow mis-configured

thought the same, but there have not been mis-configured tasks for a long time (which obviously does not mean that it cant happen)

This Atlas finished in a short time, because of a unexpected Computer-stop and a rerunning.
There is no new task starting from a other PC, so this task will never get a new running.

Not this BOINC-task got a resend, but the inside Job 3939995415 is reported as failed and re-issued as job 3942475539.
