Different RES

pepi37 · 2014-01-25, 20:15

Can someone who wrote software tell me why RES "number" for same candidate is different on different CPU-s?

If RES is some kind of "result" and if number is not prime by logic it should be same on every CPU , or not?
Thanks!

A likely reason is that there was some error during the computation on one or more of the CPUs that tested that candidate.

Yes, if there were no errors during the computation.

So one of those two results are invalid?

At least. There is also the possibility that both are wrong!
