NumberFields@Home: GPU app - beta version for linux nvidia

After all these years, we finally have our first GPU app. It's only a beta version for 64bit linux with Nvidia GPUs. Support for other platforms and GPUs will be coming soon.

If you'd like to help test this app, you will need to check the "run test applications" box on the project preferences page. I generated a special batch of work for this app from some older WUs that I have truth for. This will help to find any potential bugs that are still there.

A few potential issues:
1. This was built with the Cuda SDK version 10.1, so it uses a relatively new Nvidia driver version and only supports compute capability 3.0 and up. If this affects too many users out there, I will need to rebuild with on older SDK.
2. I was not able to build a fully static executable, but I did statically link the ones most likely to be a problem (i.e. pari, gmp, std c++)

Please report any problems. I am still relatively new to the whole GPU app process, so I am sure there will be issues of some kind.

Also, feel free to leave comments regarding what platform, GPU, etc I should concentrate on next. I was thinking I would attack linux OpenCL (i.e. ATI/AMD) next as that should be a quick port of what I did with Nvidia. I think the windows port will take much longer, since I normally use mingw to cross-compile but I don't think that's compatible with the nvidia compiler.

This will run on a 750ti and up. Should run on the 600 series also, but others have reported problems. Requires Linux and Nvidia driver 418.xx. If you can manage both of those requirements the credits are 4000/wu I believe and the wus are short, in the range of 300 - 500 seconds. This has now become an easy 100 million project if you have the gpus to support it. An app for windows is coming.

I plan on hitting it hard when the windows version hits, I keep telling myself I need some linux boxes.

Nobody has been able to get any of Fermi GPUs (GTX 4-5**) to run it or any Kepler GPUs (GTX 6-7**) other than a GTX 780. The GTX 750 Ti does run but it's a early Maxwell GPU. The project admin set the minimum compute capability to 3.5

See...https://en.wikipedia.org/wiki/CUDA

They're working on AMD and windows support also.

You can run 2 at a time on a 750 Ti and 1050 Ti 4 at a time on GTX 1080 or 1070.
