Attached is the output of CUDALucas -cufftbench 2592 2592 6. I don't get what it means by "best time" as it seems unrelated to the "ave time" values reported for the different threads.

I haven't been around for a while, but I recently started TF'ing with mfaktc on a 580, 670 and C2075. Now, with the latest updates to CUDALucas 2.05, I am actually able to run it on these GPUs...

Thanks for the tip. The E5540 is quad core, so I put "NumCPUS=8" in local.txt. It worked fine.

I am planning to try multithreading the workers when I get a chance. Last time I tried it with...

@James: I have seen all of that before, which is why I was curious to see if anything has changed.

Low and behold, it works fine now in the x64 version. Two workers split the RAM in half (almost,...

Thanks for the Windows 64 build. I will let you know if the fight for memory is fixed with 4 worker threads. Stage 1 should be done soon.

Because of the stated SSE2 bug in 25.5, I restarted all...

My rc.d start up scripts use the -B syntax instead of &? :grin: But seriously, I guess there is no reason to keep it.

Is there any chance for a FreeBSD 6 compile? Both 32-bit and 64-bit would be...

Torture Test Self Terminate Option Possible?

With multiple worker threads now possible during a torture test, any hardware failure will likely occur on only one thread -- initially. I would suggest that it is logical to automatically...

That was my solution as well:

However, when I had the problem, I think one worker was actually working properly, while the others were continually asking for memory and not getting it.

I reported this issue above. This was Prime95's response:

BTW drew, I see the same thing in the output when the workers hit stage 2 p-1.

To get around this in the meantime, I changed the number of workers to 1 and the number of threads per worker to 4. It plowed through stage 2 very quickly.

Could there be a separate option for...

I am naïve to the whole process of prime testing so bear with me here. Two questions:
Why don't the four workers each take 1/4 of the memory for their stage 2? Stage 2 can apparently work with just...

So I configured 4...
