Thanks for pointing that out. My proof-reading skills are almost non-existant.

[CODE]./CUDAPm1 -cufftbench 1 8192 1[/CODE]

is indeed what I usually run.

Sorry if this should be obvious, but I am having trouble tracking down the 5.5 CUDA libraries. Have they been posted somewhere? I can't seem to get them via the Toolkit as I don't have Visual Studio installed.

I also couldn't find them, so I ended up downloading the 853MB toolkit, grabbing the relevant DLLs and posting them to my CUDApm1 mirror site:

Many thanks, James! Did you have to install the toolkit, or were you able to dig them out of the .cab files? I went looking in the VCRedist folder, but did not immediately turn anything up.

The 853MB setup file [url=http://developer.download.nvidia.com/compute/cuda/5_5/rel/installers/cuda_5.5.20_winvista_win7_win8_general_64.exe]cuda_5.5.20_winvista_win7_win8_general_64.exe[/url] from [url]https://developer.nvidia.com/cuda-downloads[/url] is a self-extracting 7-zip file, you can open it in 7-zip or WinRAR (possibly other tools). Look in \CUDAToolkit\bin\ and you'll find the DLLs.

I had the right approach (with 7-zip). I just didn't do enough digging. Thanks for the files AND for the 'treasure map'! \bin\ marks the spot!

With much thankfulness to owftheevil and James, I now have the latest 5.5 version of CUDAPm1 running a first test on a 580 @ 830 MHz. It appears that the total time will be ~2 hours.

I ran my first couple of assignments on the last 5.0 version a day or two ago. I was startled and suspicious when both found factors: one in Stage 1 and one in Stage 2. It proved needless, but I fed them back through P95 just to be sure. Two P-1 factors in succession is a fairly unusual event in my experience. (Yes, I know that statistics have no memory, but the synchronicity did raise an eyebrow or two. :surprised)

For those who are using Carl's amazing program, may I please ask that they TF at least one candidate to 74 for every one they P-1?

We are comfortably staying ahead of (or, at least, on) the LL wave, but we've now suddenly got so much P-1 firepower that some candidates are being assigned for P-1ing TFed to "only" 73, rather than the better 74.

Aye aye, Skipper! I'll mostly be doing TF to 74 anyway, with the odd excursion into Uncwilly territory. I mainly wanted to catch up with developments (indeed amazing!) on the CUDAPm1 front, so I could be sure of how it's done.

EDIT: Once I get the 570 squared away with the proper -cufftbench runs I'll revert to my usual pursuits.

EDIT2:

Chalsall, would it work if we get p-1 assignments, notice they are insufficienlty trial factored, do and submit trial facor results, then proceed with the p-1 where no factors are found in trial facotring?

Carl...

If your program could do that, that would be *really* cool!!! :smile:

We are mostly keeping ahead of even the P-1 wave front at the moment, but there are times we release at "only" 73 for P-1.

BTW, I still owe you a *very* nice dinner here in Barbados (and, of course, my non-existent first born). Please let me know when you might be available... :smile:
