thanks a lot!
Sorry I was using __local or __global memory because I was thinking
that is impossible to allocate array whose size depends on a parameter of
the kernel. I moved it to the __private memory and now the opencl
implementation is a lot faster. I have actually problems with --dev=1
(CL_OUT_OF_RESOURCES) and with --dev=4 (Raw: 33.3 c/s real, 6400 c/s
virtual)
there is a way to pass options by comand line somethig alike: -m_cost=x ?
I need it for the auto_tune and compiling the kernel.
also for good auto_tuning I must automatically generate hashes for specified
options but this is incompatible with the actual scheme, I see this ugly.
what are your opinions?

I don't see commit ef4b3dbb anywhere, sorry
Thanks
