As per LLVM Docs CUDA compilation is supported on Linux, on MacOS as of
2016-11-18, and on Windows as of 2017-01-05
So the LLVM cuda support on windows is available since Clang 3.9 but I tried to
call a basic cuda kernel program and it crashes. I used the official released
clang version 4.0.1 x86_64-pc-windows-msvc & Clang 4.0.1 built on my machine
but the executable failed in both the cases.
#include <cuda_runtime.h>
#include <device_launch_parameters.h>
__global__
void foo(){
printf("Hello Inside Foo\n");
}
int main(){
foo<<<1,1>>>();
cudaDeviceSynchronize();
return(0);
}
clang++ HelloCuda.cu -o HelloCuda.exe --cuda-gpu-arch=sm_30 -L"C:\Program
Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\lib\x64" -lcudart_static -pthread</pre>
