Hi!

My question has nothing to do with me experiencing any kind of problems.

It is just a 'peculiarity' I 'stumbled' upon by chance, when looking at my submitted E@H GPU BRP4 'Arecibo' WU task results (something I do often, to compare, check and do my own statistics of things I'm interested in);

I know, it is required that a minimum of two of the 'same' WU (2 tasks) results from different members are checked and compared in the process of validation.

Out of curiosity I sometimes compare the run times of different GPUs needed to complete a WU (to asses my GPU performance with different drivers, settings,...) and I have NEVER before seen in a completed and validated task in one of my many 'partners' to show a RUNNING time of WU 0.00s and CPU time of 30 000 s+ (it was an BRP4 CPU 'Arecibo task').

Is this a bug, harmless error (when looking at STDERR output of the WU (task) in question there can actually be seen, that the WU run for hours) or something else?

Thank You.

Regards.

Denis

P.S.
On purpose I did not point to which task in particular I'm talking about, because at this point it does not matter and is not my concern, but should it be needed, I'll provide it.

Boinc versions 6.6.x and earlier don't report runtime, that was first added for Boinc 6.10.x

Thank You for the

Thank You for the answer.

I also had thoughts, that it could not be a 'serious' bug, even before I wrote the first message, but nevertheless I learned something new now and that's always a good thing, no matter how small the 'puzzle' piece in question may be.

Regards.
