The 1000 is an arbitrary limit I put in so that enough candidates are available, thats when the GPU is used the first time.
Are you interesting in makefiles for cuda enabled version?
PS is it intened to allow it to work only for sm_20+ devices?

Aha
Seems like it starts failing if more then 1000 prime chain candidates found

Code:
Cuda finished
Added 361 addresses from 199.83.89.217: 180 tried, 12837 new
Added 199 addresses from 199.83.89.217: 180 tried, 12827 new
Have 1314 candidates after main loop
[0] start
[0] candidate is 1edf6ebf2abf2b6396b2f78eacddc21a2f9c0b963356d861e2035aa210ed01e094668

update: added a stroxl function from http://www.jbox.dk/sanos/
The code still needs a lot of debugging and the mpz cuda library + string functions a lot of testing, if any CUDA developer wants to give it a chance, go for it!
Weather is too good outside to continue this now...

Code compiles with some makefiles modifications but fails near imidiently with memory errors
Code:
Cuda finished
Have 250 candidates after main loop
Cuda finished
Have 344 candidates after main loop
Cuda finished
Have 312 candidates after main loop
Cuda finished
Have 1235 candidates after main loop
Cuda error: cudaMemcpy: cudaMemcpyDeviceToHost, unspecified launch failure
Also current code will only works with sm_20 and higher devices

Nice work OP. I will just wait for the nice folks to provide a one-click Windows 7 miner 
Meanwhile I have to find my nVIDIA GPU and see whether its alive. I think it was a 8400.

Great initiative and looking forward

anyone here working with him? .. seems like he wants devs to step up and work on a client with him, asking if its done or something is prob not the right thing here..
July 19, 2013, 04:49:50 PM
what about the perfs of this client?
Insane perfs. As soon as you gracefully push your BigInt lightning fast and reliable cuda library.Any ETA on that ?

have you seen the cuda gmp pdf?

cheers on not being greedy, btw i have many nvidia cards sitting idle here in our office

Very much agree. A public release to a larger group of people is the best for Primecoin.

I also have several nvidia cards around to test on. Just 2x 240's but hey its testing isn't it? lol
I have a 550Ti I can run it on

I have a few nVidia cards I would be happy to test early betas on.
Ditto.
Thank you for taking on this project.

Have to mention that I prefer a Win 7 x64 build over Linux since I run Win 7 native and VM's tend to be quite a bit slower.
