2019-03-22: 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.

2019-03-22: NumberFields@home,发布了Linux系统下NVIDIA显卡的测试版计算程序
目前发布的仅为64位Linux系统下NVIDIA显卡的计算程序(beta)。其他平台和显卡的计算程序将陆续发布。
如果您愿意帮我们测试这个程序,请在项目设置中勾选“运行测试计算程序(run test applications)”。
一些可能会出现的问题:
1.该程序使用Cuda SDK版本10.1编写,所以会需要比较新的显卡驱动版本以及only supports compute capability 3.0 and up 。如果不能满足此条件的人过多,我会考虑用老版本的SDK重建程序。
2.(开发问题)
*后略
