      BOINC 6.10 and all of 6.12 don't do OpenCL detection, that's BOINC 6.13 only so far. But 6.13 is far from stable.

        No chance to participate here without that buggy stuff?
        OK, NNW then.

        Edit:
        Wron thread, I'll start a new one, sorry.

          Even with Boinc 6.13.12, 64 bit, Linux , I get

          This is even tho boinc seems to recognize the ATI card as an openCL capable GPU:

            Hi!

            Just for the records, I think in my case the problem was a missing 32 bit version of libGLUT . Blessed are those who can read ... developer release notes :-)

              Ok, I finshed the first two OpenCL WUs and both failed.
              The first one was probably due to old ATI driver software.
              The second one appeared to be running fine and then failed.
              My test machine 64Bit Linux, Catalyst 11.11 a,d SDK 2.5

              As a side note: The GPU app uses around 100% CPU as well.

                Hi!

                Yeah, seems to suffer from a problem I see as well: BOINC will terminate the task prematurely as it exceeds the max allowed runtime. I assume this is a problem in the work unit generation.

                Hi again, Three more WUs

                  Hi again,

                  Three more WUs have been terminated after almost exactly 3935s. At least the error is reproducable.
