Mattia:
If you need, I have an Ati 4850 under linux for the beta testing... but I'm not able to enter beta section.

Raistmer:
No linux port exist for now, maybe in future...

Raistmer:
Version for single / multi-GPU, w/o double precision support posted in beta area

Only part of algorithm ported to GPU (hence "hybrid" build) and ported part is heavely memory-bound so sometimes 2600 performs better than my HD4870.
Exact speedup should reveal beta testing.

System memory bound or video memory bound? 

Raistmer:
GPU part GPU memory bound and CPU part - system memory (especially on P4 where L2 not enough to hold many of used arrays...)
AP likes big L2 cache, all builds including pure CPU one.
