    Computer 12492607

    Work unit example:-

    Name: LATeah1064L12_452.0_0_0.0_20332046_0
    Workunit ID: 463702827

    Outcome: Computation error
    Client state: Compute error
    Exit status: 11 (0x0000000B) Unknown error code
    Computer: 12492607

    All my units after rejoining are failing and I do not know where to start looking. I suspect that the problem revolves around this line:-

    read_checkpoint(): Couldn't open file 'LATeah1064L12_452.0_0_0.0_20332046_0_0.out.cpt': No such file or directory (2)

    Any help in pointing my nose in the right direction would be much appreciated.

      Hi and welcome back!

      The line about not being able to read the checkpoint is normal when starting a new task from scratch.

      I looked at a few of your failed tasks and in the Gravity wave tasks this message is logged:

      OpenCL is not available with these features!

      The problem seems to be with your graphics drivers and OpenCL support.
      Try downloading and installing new drivers from AMDs website.

        Thank you Holmis.

        I will try that and then wait until I can get work again. I had not thought of that going wrong. I should add a caveat that I run Milkyway@home too and I have no problem with GPU tasks. Time to start digging and once again thank you for your assistance.

          Good morning Holmis.

          I reinstalled the video-drivers and sadly that did not work. Oddly when I got work Boinc got sticky and would not respond when I tried to stop EInstein.

          I have subsequently changed settings to one task per gpu where that figure was two. Before I forget the error message was the same as last time.

          My startup info may help shed some light on the matter:-

            I don’t think Mesa is suitable for Einstein. Try the AMDGPU OpenCL.

              I've got no experience with GPU crunching under Linux as I'm a Windows user. But I seem to remember others having problems with Mesa drivers here at Einstein. I'd follow Marks advice and try the other driver type.
              If you need help then I'm sure some of our resident Linux users will chime in and help get you going.

                It's not clear which video drivers you reinstalled, but you will need to run:
                ~$ ./amdgpu-install -y --opencl=legacy --headless
                from within the directory newly of the released amdgpu-pro-20.20-1089974-ubuntu-20.04 package (downloaded from here, https://www.amd.com/en/support/graphics/radeon-400-series/radeon-rx-400-series/radeon-rx-480). Read the included install documentation to know what's what.

                The Mesa video drivers are fine, but you need AMD's OpenCL 1.2 for crunching on the rx480s. The earlier AMD Radeon driver stack didn't play well with Ubuntu 20.04, but the recent AMD update to is supposed to have fixed the issues. (I'm still on 18.04, so haven't tried the latest AMD offerings.)

                If you previously installed any AMD Radeon drivers, you will need to run amdgpu-pro-uninstall before installing the OpenCL drivers. (This is true for any AMD Radeon driver installation or reinstallation.) There is no need to reboot after the uninstall, just do it after the --opencl install.

                Ideas are not fixed, nor should they be; we live in model-dependent reality.

                    I had not tried a headless install. I have now done as you suggested and removed this lie from cc_config.xml:-

                    <use_all_gpus>1</use_all_gpus>

                    That move disabled the "mesa" GPU's!

                        Hooray!

                        I managed to solve the problem and am now happily crunching Einstein work!

                        Solution:-

                        ******** It looked a bit funny that I had 4 GPU's recognised by BOINC. ********

                        1). Shutdown projects - no new tasks and suspend.

                        2). Shutdown Boinc service.

                        3). Uninstall the amdgpu-pro installation.

                        4). Reboot.

                        5). Run sudo apt purge mesa-opencl-icd ********

                        6). Reinstall (full) amdgpu-pro and reboot.

                        7). Restart Boinc.

                        8). Restart projects one at a time.

                        9). BULLSEYE!

                        I do find it interesting that Milkyway could recognise the mesa drivers and Einstein not. I suspect that any pre-existing opencl package should be removed before installing the amdgpu-pro stack.

                        Finally Thank you Cecht, Holmis and Markj for helping me along the way.
