:gah: Sorry... just noticed that I had the 4096K FFT specified in the ini file.

Is this developed enough that benchmarks would be able to be added to mersenne.ca?

[QUOTE=Jayder;421726]Is this developed enough that benchmarks would be able to be added to mersenne.ca?[/QUOTE]
Yes.

Does it have support for worktodo.txt and/or output results to results.txt?

[QUOTE=Jayder;421726]Is this developed enough that benchmarks would be able to be added to mersenne.ca?[/QUOTE]

This would be a great idea! It would then allow James (if he has time) to do an analysis as to the "optimal cross over points" for TF'ing vs. LL'ing for AMD GPGPUs like he's done for NVidia's offerings.

[QUOTE=UBR47K;421795]Does it have support for worktodo.txt and/or output results to results.txt?[/QUOTE]
both support.

1.04 binaries for windows.. be sure to try -sixstepfft :smile:

EDIT: I wonder what kind of performance you can get out of something like a FirePro W8100.. it's basically a R9 290 with 1/2 DP instead of 1/8 for the R9 290
