An Open-Source GPGPU Compiler...

This could be of interest to computer chess...

Anyone able to compile Stockfish using this?

As I understand, this is a CUDA compiler;
You can't simply grab existing C++ source and magically benefit from GPGPUs
You have to write carefully optimized CUDA kernels, memory management is also tricky.

As I understand, this is a CUDA compiler;

Yes, it seems to be an open-source alternative to nvcc, Nvidia's proprietary CUDA compiler. It can compile CUDA kernel code to PTX (nv*s ISA) which is run by nv's device driver via just in time compilation.

...in some cases of simple data or task parallelism compiler directives could be enough to make use of GPGPU.

I agree, it can be tricky to map a problem onto GPU.

...btw: AMD released HIP, which should be able to run CUDA code on AMD GPU and CPU devices.
