GPU and CPU compilation possible #117

Open erikzenker opened 8 years ago

erikzenker commented 8 years ago

This PR provides HASEonGPU the ability to compile for CPU and GPU. The GPU back-end is used when CUDA was selected by compile time option, otherwise the CPU back-end is used. It is currently no possible to select the back-end on run-time, because nvcc is not able fully compile the CPU back-end code of alpaka.

This PR needs to be followed by performance checks.

Well, alpaka is not compiling with gcc 5.2. It is time for a module system on our drone server.

Alpaka could also be fixed to be compileable with gcc 5.2
