    Today I upgraded my Raspberry Pi (B+) to the latest operating system (Stretch from Jessie). Now I'm unable to get work from Einstein@home and my account shows that I have 17 work units with "Error while computing." All are dated today (1 September).

    What do I need to do to get this Pi back to crunching for Einstein@home?

    If it matters, the Pi runs headless, connected to an external USB hard drive, so any configuration will have to be done via SSH.

    Thank you for any assistance you can provide.

      Assuming you have a Pi2 or Pi3 seeing as your computers are hidden, Login to the e@h website. Go to Account -> Preferences -> Project and set "run test applications" to yes. After that tell the Pi to do a project update and then you can request work. That will get you the faster 1.47 BRP4 (beta) app that works fine under Stretch.

      If you have a Pi zero, B or B+ (that is an ARMv6 processor) then you're out of luck until the project recompiles the BRP4 app.

        Thanks, Porkypies, for your reply. The Pi I upgraded is a B+, so I'll have to wait for a new compatible app from the Einstein project. I hope one will be forthcoming, though I doubt it's high on their list of things to do.

          Hi,

          I appear to be having the same issue as well as BOINC always deferring communication for 7 hours.

          I've had several Pi Zeros running E@H for well over a year and they are still getting tasks now. However, I recently reinstalled the OS on a Pi 2B to the latest Raspbian and it isn't getting any tasks.

          When I issue the "Update" command it just defers communication for 7 hours. On my E@H account I can see 40 tasks all of which have "computing error".

          I have enabled "run test applications" but no luck. I am using BOINC from the Raspbian repos.

          Any suggestions?

          Thank you.

            Your computers are hidden so nobody but you can see what the problem might be.  Here are some guesses.

            1. The error tasks may have caused you to exceed your daily limit.  You should see something about this in the BOINC event log and the backoff should be sufficient to take you past the 'end' of the current day - midnight UTC,  about 2.5 hours from now.
            2. The scheduler might be unhappy about some aspect of your preference settings or configuration.  You need to look at the scheduler logs for information in the messages recorded there.  There is a guide to using these logs posted in the Getting Started forum.

            If you don't know why you had so many compute errors, you may be able to get information about that by clicking on the task ID of one of the failed tasks on the website.  You will at least be able to see any error messages that were returned with the failed task.

            Good luck with sorting out the problem.  I have absolutely no knowledge about the Pi so I can't be of much help.

             

            Cheers,
            Gary.
