Compiling and building OpenCL programs takes too much time on compute2

Description

The AMD compiler is very slow compiling OpenCL code, especially if using multiple GPUs. Creating a FFT plan on all four devices for a round-trip transform, takes about 34 seconds, the actual computation just a fraction of a second.

Caching the binaries in the framework would not be a big deal but for third-party libraries (e.g. Apple FFT) this becomes cumbersome.

Low quality hardware solved the low quality software problem for now. None of the cards still have cooler running. ipepdvcompute2 now runs Intel and Nvidia.
