Hi,

The sem_wait stuff is related to some AMD/NVIDIA bad relationship. On a 
clean AMD machine, it works fine on 2.6.

I can do some performace test, if you think is useful.

By the way, the machine i reported the error some days ago (and did the 
same magnun did, OpenCL AMD CPU) has a AMD Radeon HD 6370 DDR3, 512 MB 
with 2 stream cores.

New hardware for poor countries:

    Subject: OpenCL patches

    Samuele, Lukas,

    I just committed a couple of trivial OpenCL patches to git (after
    manually syncing with Samueles tree). Among other things I added support
    for --platform. With this I could successfully chose whether to use CPU
    or GPU. I also plan to support --platform=LIST (I added a temporary
    separate tool to unused/ for now).

    I think we should rename --gpu to --device before next Jumbo release,
    because it doesn't really have to be a GPU.

    I also tried AMD's version of OpenCL for CPU. Worked fine. I can't
    really compare performance because this was on a machine in an whole
    different league. I had some problems (sem_wait() failed, seems to be a
    common regression problem) with AMD APP 2.6 so I reverted to 2.5.
