Thanks to Mariusz Uchronski at pwr wroc pl, the single precision OpenCL version of Hydro works now on an AMD Radeon HD 7660G.

Currently (to my knowledge) the OpenCL works in SP & DP (+MPI) on the following machines

- NVIDIA M2050, M2090
- INTEL SandyBridge	(beta compiler)
- INTEL Xeon Phi	(beta compiler)
- AMD Radeon HD 7660G
