    I don't mind any debugging I can do, if you don't mind sending me detailed instructions. I'm afraid I'm pretty new at Macs.

    I did download the CUDA software in your last post, and installed it. This time, my log says:

      I downloaded the driver you suggested. I still don't get any tasks. It looks like it doesn't see the CUDA driver. But I did install and reboot as you suggested. The scheduler log still shows:

      You now are showing a message that Cuda support isn't available, see the earlier post about Cuda support being disabled on dual-GPU MacBook Pros. (you're got a Nvidia and an Intel GPU)

      What does Boinc 7.2.28 show? Charlie may have re-enabled Cuda support on that version, it does have the following changeset:

      Quote:

      client: optionally detect GPUs via a child process, for dual_GPU laptops.

      Some dual-GPU laptops (e.g., Macbook Pro) don't power down the more powerful GPU until all applications which used them exit. To save battery life, the client launches a second instance of the client as a child process to detect and get info about the GPUs. The child process writes the info to a temp file which our main client then reads. This option is enabled at compile time by defining USE_CHILD_PROCESS_TO_DETECT_GPUS as non-zero in gpu_detect.cpp

        Thanks to all who replied.

          Thanks Claggy, I didn't pay enough attention to the BOINC version Richard was using.

          For the sake of completeness: I tested 5.5.28 on a OSX 10.9 machine with a Quadro 4000 (> sm_1x GPU) and BOINC 7.2.28 - it's being recognised without a problem.

          To conclude: to get CUDA 5.5 working on MacBook Pros with OSX 10.9 Mavericks you need to:

          • * Install the latest CUDA driver from NVIDIA (CUDA not supported by stock driver shipped by Apple)
            * Install the latest BOINC client software
            * For the time being: use a > sm_1x GPU (Fermi and newer) until NVIDIA releases a driver update to support older GPUs again

          Cheers,
          Oliver

              FYI, "you" in Claggy's port most likely means this host: http://einsteinathome.org/host/9284410/tasks.

              Error 700 often means that the CUDA device context was invalidated for some reason. Richard, did you try to switch the GPU manually or can you think of a situation where OSX might have tried to do that?

                No, absolutely not. In fact, I don't think I could if I wanted to.

                I see that one cuda wu just went to a ready to report status. No sign of an error here, but let's see what this shows, when it reports.

                  These are your errored tasks:

                  Error tasks for computer 9284410

                  Edit: I've reported the three Mac GPU error threads to the Boinc Alpha list in hope that the Mac developer comes along and has a look.

                    Richard, you might want to try this tool. It allows you to monitor which GPU is being used. It also allows you to set the active GPU manually, disabling automatic switching. It would be interesting to know whether the errors you get still appear when you manually switch to the dedicated GPU before you start BOINC (any GPU app in BOINC). This way we should get an indication whether the errors are caused by GPU switching or not...

                    Best,
                    Oliver

                      Let's see what happens next time I report a cuds wu.
