A few of my workunits have had abnormally small run times. I thought the run times for all work units was set to 2 hours and thought it was best to report this here if this warrants a closer look.

https://boinc.loda-lang.org/loda/workunit.php?wuid=2599141 - 297s
https://boinc.loda-lang.org/loda/workunit.php?wuid=2599156 - 270s
https://boinc.loda-lang.org/loda/workunit.php?wuid=2599261 - 153s
https://boinc.loda-lang.org/loda/workunit.php?wuid=2599315 - 53s
etc.

I'm not sure if these were marked completed due to some out of memory condition or some other system/ network error as these appear to have completed at the same time. However, they've all passed validation and I've received credits for them. The task outputs do not show any errors and the LODA logs page is blank.

Thanks for reporting it. We'll look into. I checked some other results and they look normal. Not sure why these were so quick.

I saw this happen again today. I have LODA running with resource share 0 (i.e., only download work when my other projects do not have any work). I had 16 LODA tasks running when I received some LHC tasks with an earlier deadline. My system automatically paused the LODA tasks (status: "Waiting to run") and proceeded to run and complete the LHC tasks. After a couple of hours, when the LODA tasks that were at varying %s of progress got their chance to run, the tasks immediately "completed" and were reported as valid.

E.g.,
https://boinc.loda-lang.org/loda/workunit.php?wuid=2685909
https://boinc.loda-lang.org/loda/workunit.php?wuid=2685639

I have the option for setting "Leave non-GPU tasks in memory when suspended" checked in BOINC.

I managed to freeze network communications and captured this output file for wu_1670076947_34367_0. It appears the task abruptly "completed" after resuming:

I noticed something that may be related.

1. When LODA tasks are in a Waiting to run or Suspended status in BOINC, the process in Windows Task Manager shows it is Suspended. Tasks for other projects do not appear to do this.

2. The memory for the LODA tasks in the Suspended state as seen in Task Manager drops over time.

3. When resumed, the LODA tasks "jump" in % completed, either directly to 100% or to a higher percent complete. It's almost as if the system thinks the task has been processing something while it was suspended.

Here's a snippet from when this LODA task fluctuated between Running and Waiting to run, with my indicators for when the switch happened. The progress completed %s appeared to increase proportionally to the time the task was not running (related to the standard 2 hour runtime?):

Can you maybe try to reduce the number of parallel / sleeping tasks?
You can set the Max Number of Jobs here (maybe also supported in other projects):
https://boinc.loda-lang.org/loda/prefs.php?subset=project

As I run LODA with resource share 0, I only get the tasks needed to keep my CPUs busy (16 at a time for the 16 threads) and have no queued LODA tasks at any given time. However, if I get work from another project with an earlier deadline, BOINC suspends the LODA tasks while it works on the ones that expire earlier.

I will stop requesting work for other projects if I'm running LODA going forward until this is addressed.
