Currently we only have 32 bit application binaries available for the Open Pandemics project on the Linux on ARM platform. It is possible to run the 32 bit application on a 64 bit operating system but it requires a workaround in the BOINC client to allow work to be downloaded. To obtain the 32 bit application binary and tasks you must modify the cc_config.xml file in the BOINC data directory. The tag below alt_platform must be added in the options section. For more discussion on this please see the following thread:

Thank you Jonathan for the info.
----------------------------------------As soon as I will receive my RPi 4, I will try it on a 64 bit OS (probably Ubuntu Server 20.04). Cheers, yves |

Hello,
----------------------------------------on my odroid N2 with linux I´m using the following three alternate platform informations: arm-unknown-linux-gnueabihf armv7l-unknown-linux-gnueabihf aarch64-unknown-linux-gnu I found this informations on other Boinc forums. With OPN this setting works fine, also with rosetta. If the Beta of MCM runs with this parameters, i can´t say, i got no beta-WU on this machine (only on android) Thanks Umlauf [Edit 1 times, last edit by Umlauf at Jul 30, 2020 11:21:26 AM] |

Yes, MCM is running with the same settings as OPN1. If your odroid N2 is able to run OPN1, then you should be good to go.
Thanks, -Uplinger |

FYI: after a couple of boinc crashes on my 2 RPi 3B running Raspios (32 bit), I notice that it is necessary to extend the swap file size from 100 MB to 512 MB.

This ARM tasks/app can run on x86-64 (AMD64) with qemu-user-binfmt or qemu-user-static. The task is valid, everything works, very slow.
OPN1_0036790_06830 Status Sent Time Return Time Hours Claimed/Granted  Huge claimed credits on a slow 47.83 hours CPU time for ARM task on x86-64 CPU (AMD64). I had alt_platform ARM manually added, and now after I saw how slow it runs, turned off this alt platform. This was a nice experiment to see if qemu-user runs faster or slower then real ARM hardware. CPU: AMD FX 4100. My CPU average is 3.2 hours for each OPN1 x86-64 task. |

Slightly out of topic but has anyone got any tasks for Raspberry PI Linux since last failure?
----------------------------------------I got OPN tasks on the 7th last (resends). But nothing since it started flowing yesterday and i have a "5 minute check for work" script running. For Android ARM i get both MCM and SCC.

I've not seen anything for RPi recently, setup for 64 & 32 bit. |

Glad to know it's not just me who receives no tasks for ARM machines for months now. Unless there is a solution in circulation?
