[Cin] OpenCL benchmarking ....

[Andrew Randrianasulu]

Hi all, and happy editing

Not VERY useful for CinelerraGG yet, still I found whole topic attractive enough :}

http://www.bealto.com/gpu-benchmarks_mem.html

I compiled benchmarks for my machine, with two simple fixes, and uploaded result to github:

 https://github.com/Randrianasulu/MPBenchmarks

IMO my current devices quite fast:

For fastest NVA3 gpu (reclocked manually)

GPU<->GPU copy still slow .....

This is with very hacked mix of two experimental mesa branches ...

Master (mesa3d) doesn't support compute on nv50-era cards.

This bench requires images(2D) support, and works with OpenCL 1.1 driver
