    Today I moved 5 arm based machines from seti@home to this project.  3 of the machines received work but two didn't.  All 5 worked with seti@home.  Here is the log from one of them, any help much appreciated.

      The project doesn’t have aarch64 apps. If these are Raspberry Pi’s then you can run the standard armhf app, just turn off 64 bit mode.

          If it’s a 32 bit Ubuntu then that might work.

          There are volunteer created aarch64 apps for the BRP4 work and others if you are willing to use the anonymous platform mechanism. Contact N30DG-ARM to get a copy.

          See https://einsteinathome.org/content/parallella-raspberry-pi-fpga-all-stuff?page=105 which I would suggest you start at the end of, it’s rather a long message thread.

            Hi Jim, welcome to Einstein!

            This is a message posted by N30DG-ARM late last year.  Seems like a good place to start.  If the link doesn't take you to the correct message, it's dated 9 Nov 2019, message number 174272.

            I see there is also a comment there about the newer gamma-ray pulsar app (GRP) as well as the older binary radio pulsar (BRP) app.  I know nothing about your type of hardware so don't know if that is relevant.  Unfortunately the GRP app needs a lot of memory per instance.  I only mention it because that search is probably of much more interest to the project these days :-).

            Hope everything goes well for you and you find an acceptable solution.

            Cheers,
            Gary.
