Compiling with CUDA

[huhlim]

I'm using a CUDA 9.2, and the nvcc did not support -arch=sm_20 option. I simply fixed the issue by replacing sm_20 to sm_70 in CMakeLists.txt file.

With -arch=sm_70, I could compile it, but the compiled version failed to run on GTX980Ti.
By using -arch=sm_50, I succeeded to run it.

Thanks for reporting the problem @huhlim. Unfortunately, I do not have any cuda experience nor a graphics card so I cannot help maintaining the cuda support.

I will leave your issue open as your fix may help others struggling with cuda.

Thanks for leaving this up! This fix also worked for me.

Hello, I've done the same but then I got the following error:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/string.h:61:15: fatal error: 'string.h' file not found

does anyone know how to fix it?

@bognabognabogna I think it is a completely different issue with your MacOS environment.

Hi all, please check out #20 to see if you can get this running on your machine with CUDA now.

Since this issue is still open - just noting that this does work on latest CUDA versions now. Thanks for the fix!
