Different RES
 
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!

[QUOTE=pepi37;365372]Can someone who wrote software tell me why RES "number" for same candidate is different on different CPU-s?[/quote]A likely reason is that there was some error during the computation on one or more of the CPUs that tested that candidate.

[quote]If RES is some kind of "result" and if number is not prime by logic it should be same on every CPU[/quote]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!
