I always wish to ask this, and i foun one example now.

I now they both ends on an overflow, but all the numbers match, at least for my untrained eyes.

Can anyone explain why the WU is Completed, validation inconclusive?

Thanks in advance.

It's usually because 2 different GPU s got very slightly different overflow results

I see that in this case one is GPU and the 2nd result returned is CPU

One of the other tasks should be a tie-breaker.

But an overflow is an overflow no matter from where it comes GPU/CPU.
The data is not valid anyway.

Because the results DON'T match

What about the "strongly similar"?

In normal times, because each of the 30 signals has to have a matching signal in the wingmate's result, matching to several decimal places on each of the metrics.

But at the moment, it's easier than that: every overflow is being triple-checked, because of the GPU driver problems.
