This is from msft's code, but the windows exe I have given is not (yet).

Latest data on my 7970 after updating the fglrx driver from 13.6 to 13.8 beta2, which fixed the speed issue:

[/code]So now the question is, how do we submit this back to mersenne.org, as it doesn't accept the clLucas line at the moment? Is there an equivalent format for CUDALucas that we could use, for example? My getwork/submission script is working otherwise...

Edit: submitted as CUDALucas :-/

Hi,

I could not spend a lot of time, but a few observations:
(HD7850@1050MHz)
[LIST][*]-aggressive does not change iteration times a lot (if at all), it just consumes one CPU core.[*]when continuing from a checkpoint, the first output line does not consider the real number of iterations, but instead calculates based on the reporting interval.[*]the default 256 threads is too much - I'm much faster with 128, and yet a bit faster with 64.[*]an -fftbench option would be good (or did I just not find it?)[/LIST][code][H:\software\clLucas]clLucas_x64.exe 3666666

r = 0.1191 (0:08 real, 0.8114 ms/iter, ETA 45:10)

[QUOTE=kracker;353331]Also, I noticed I can not pass -threads and -f at the same time, it gives me "over specifications Grid = 65536"[/QUOTE]

This happened to me with -f 4194304 -threads 64, but the same FFT with -threads 128 seems OK.

[QUOTE=Robish;353334]Thanks Kracker

Tried 3666666 and got the following seems very FAST :-)

Actually, what msft wants is 36666666 not 3666666 :smile:

Hey, I've got link errors at link stage when using MSVC2012 on Win8 x64 environment. AMD FFT was compiled separately and fed through include/lib. Project files were from matrix multiplication.
