I noticed this task that was run on my machine dingo4 and also validated by dingo4. This is not the normal way BOINC works as it could lead to cheating.
Task:

it's a miner type application
why is the validation quorum set for tasks at all?
what will be compared in two different results?

There is an additional validation on a server (separate from the BOINC infrastructure). I need to look into the BOINC config.

Maximum number of attempts for a work unit is I believe set when a batch of work is uploaded to the server. I don't know exactly where in the files uploaded to the server though. I see one of my tasks has _6 at the end of the task name indicating it is the 7th attempt whic seems a little excessive!

I am seeing a number of my tasks failing validation due to "Exceeded time limit of 18,000 seconds"
They all run just short of 5 hours.
I have also seen a number of my takes that fail (probably the "fails validation" tasks) that run a lot slower than most of my other tasks.
I have a 12 core 24 thread computer with 32 GB of RAM, at times all 24 threads are using 1 GB of RAM per task.
Perhaps some of my tasks are failing (the ones I have with the error code exit 195) because they need more RAM and have a hard limit on them making them stop start trying to get more RAM and so run slower than normal?
By running slower they then hit the 18,000 second time limit and fail to validate, or just fail altogether?

This "reached time limit of 18,000 seconds" is becoming an issue, I have now gotten 33 validation fails due to this problem.
On this new host I downloaded 262 work units, 151 have so far completed normally, 33 have validation fails and 27 have the "exit 195 error".
So of the 211 work units so far processed 60 have failed (28%}, that is a very high failure rate don't you think?
I noticed that the work unit seems to know from just after it starts that it is going to run a long time as the estimated run time is higher than a normal work unit.
Also after reaching a certain percentage done point (anywhere from less that 1% to over 97%) the percentage no longer advances even though the work unit is using the CPU and appears to be working.

We have fixed the "reached time limit of 18,000 seconds" issue in the new app version 220610. It should not occur anymore. Please let us know in case you still see validation errors.

Thanks for that Christian for that, I currently have a number of the older version 2022.06, when they flush through I will test the 2022.10 version.
Thanks
Conan
[PS] Just an aside I have seen random work units run to over 8 hours, one even validated, so they don't all stop at 4 hours 57 minutes 33 seconds (18,000 seconds).

I find it interesting that many of my time limit errors are pretty much the same length of time as my tasks that validate.

I am still getting error "reached time limit" on my 2206.10 tasks...
I just got one on this WU
Timed out at 11,159.30 seconds.
Not the 18,000 seconds I had before, just 3 hours 6 minutes instead of 4 hours 57 minutes.
So the 2206.10 tasks still have issues.
Conan
[PS] Also had a 2206.10 that started got to 0.100% and was still at 0.100% after 2 1/2 hours with 75 Days to go, so I aborted that one.

App version 2206.11 is available with improved configuration. We'll monitor the results.

This version has too high an error rate.

Yes, we also observed timeouts with 220611. To mitigate the issues, we have reduced the task size to 50% in the new app version 220612. We'd appreciate if you try it out. We'll investigate all issues.

Thanks Christian,
Running 2206.12 now and have had 3 failures in the first 19 work units.
This one had the same issue that 2206.10 did with the exact same time out time of 11159.30 seconds, a bit like a re-badged work unit but getting the same result.
This WU had the "exit with code 195" issue and I had one other of this type.
But mostly they are running much better that earlier versions, at least so far.

I found logs only for the first WU that you mentioned. It's strange, because the logs show only 10 mins of runtime. Not sure what happened there.

Hi Dr Who Fan,
thanks for sharing the details of the WU. Based on the logs, I assume the miner was either busy validating an exceptionally slow program, or the process got somehow halted. We'll try to improve our logs and progress reporting to be able analyze such issues better in the future.
I checked your results so far: 57 successful, 2 validate errors, 2 errors. We'll try to improve the success rate further.
