[QUOTE=ATH;555874]I kept getting those mismatches even on the new V100 cards. I'm pretty sure now it is because gpuowl chooses a too low FFT size for those 54M exponents: 2.75M FFT.I'm now forcing it to use 3M FFT and have had no mismatch so far.[/quote]

[B]Why don't you just try this older version compiled by Fan Ming. for LL-DC, which can be run immediately with Colab-Ubuntu.
I've never had an incorrect result with it, even in LL-DC.[/B]

This has been picked up by random user. Will monitor.

When you take an exponent say "I have taken" or something like that. "Request" is used to ask for someone else to test a mismatch you had.

Did you try 54M exponents? I have done 350+ DC in 50M-53M without any incorrect results with the version I'm using, I just think I reached near the end of the 2.75M FFT that gpuowl chooses.

[/URL][/B][/QUOTE]Do you manually go through that looking for mis-matches?

[B][SIZE="1"]Yes, but only sometimes. Simply sort the exponents in ascending order and look for the residue[/SIZE][/B]

[QUOTE=ATH;556134]Did you try 54M exponents? [/QUOTE]
Not yet, but 53M with 2.75M FFT

Alright. Thanks.
