Do you save M23102129 and M22094129 10000iterations Res64 Dump ?

When receive kill signal MacLucasFFTW make checkpointfile.

And -cN option Create a new checkpoint after every N iterations.

For M23102129, I think this is the 10000th iteration:
M( 23102129 )C, 0xbbbbecc86d34055f, n = 2097152, MacLucasFFTW v8.1 Ballester

I don't have the one for M22094129. Hopefully the second double check will come back soon and conclusively determine if the CUDA residue is correct.

Now I start M23102129 with GTX260 and M22094129 with Q8400.

Hi,
Version "C" at .0121 sec/iter for the 2048K FFT and .0229 sec/iter for the 4096K FFT on GTX260.
Thank you,

Did anybody test the following with GPU/CUDA?

1 - A known Mersenne Prime
2 - A Mersenne number when CPU cores are busy with Prime95/mprime ?

Yes. M216091 and M24036583 have been successfully verified.

As for the 2nd part of your question, I really donĀ“t know.

Now testing M23102129 with GTX260(GPU/CUDA) and M22094129 with Q8400(Prime95), It is same machine ;-p

I have a GTX 285 that I will be installing in my Mac Pro today.

I'm happy to run doublechecks, so which version of MacLucasFFTW is likely to give best results ....

you can download MacLucasFFTW.cuda.C.tar.gz,
and test performance no change version and delete -DTESRA from Makefile version.
Thank you,
