    It looks like as of Aug31st of this year, a Linux Intel GPU application was put up. https://einsteinathome.org/apps.php

     

    and that seems to correlate with Bernds recent post on the subject of Intel GPUs. here:https://einsteinathome.org/content/brp4-intel-gpus-and-validation

     

    I just got a new laptop with Intel Xe graphics. I wanted to try the application just to test performance. I don't really intend to run a laptop crunching a lot, I just wanted to try this application out to see if it worked for Xe and see the performance.

    but it seems the scheduler is gatekeeping the application from being sent to me solely on the basis of device name, instead of capabilities. https://einsteinathome.org/host/12901081/log

    has anyone been successful in receiving this application on Linux? if so, could you please post your coproc_info.xml file contents? I can massage the contents of my file to match to force the scheduler to send me the app and some tasks. I've attempted several permutations of 'HD Graphics [some number]' but nothing seems to get by this scheduler check.

    Mine are mostly Intel(R)

      Mine are mostly

      Intel(R) HD Graphics 4600

      but that's

      a) under Windows
      b) older runs (including BRP4G the last time it was run)

      I promised Bernd I'd try some test runs while he's away from his desk this month - maybe when the weather breaks on Thursday.

        is that what the <name> field shows in your coproc file?

            thanks, either this gets formatted differently on legitimate Linux hosts, or the scheduler is bugged and wont let anyone get work.

             

            with my spoofed coproc file: https://einsteinathome.org/host/12901081/log

            still fails

              So, the allocation failed for the stock app because the 'HD Graphics [123]|HD Graphics 40' test failed, but was allowed for a Beta app. It's running now.

              The applications page says that there are Beta apps for Windows and OS X, but not for Linux.

                yeah. this is a Linux machine, so beta is of no help here. I'm specifically trying to get the newly added (revitalized) Linux app for testing. sounds like something needs to be tweaked on the Scheduler side.
