You in theory can run the 32bit armhf apps on 64bit aarch64, On a Debian base you can. Just not sure how to do it on your OS.
Once you have the right dependencies installed you just need to add to cc_config.xml file in the options section <alt_platform>arm-unknown-linux-gnueabihf</alt_platform> and boinc can work both types. |

Do you know the dependencies and how to add them? When I change the cc config it downloads work units but they all error out

I'm running Raspbian Buster Lite OS on a Raspberry pi 4 and working very well with this project.

Raspbian Buster is a 32 bit OS last I checked. If you have a RPi4 you can get up to a 50% performance boost switching to a 64 bit OS
https://www.cnx-software.com/2020/01/29/raspb...bit-and-64-bit-debian-os/ But if you use a 64 bit Linux OS with ARM (such as the raspberry pi 4), you will lose the ability to run OpenPandemics because they did not compile a 64 bit runtime |

Does that 64 bit not run the 32 bit version? There used to be a need to add certain libraries, as it would not always do that out of the box.
----------------------------------------Surprised to hear of 50% performance differential. The sales pitch for Linux/Windows/MAC at the time was a gain of 4-8 percent for the 64 bit WCG science app builds. [Edit 1 times, last edit by Former Member at May 25, 2020 1:04:18 PM] |

64 bit kernel and 32 bit kernel are present in lastest Raspbian, you can choose
----------------------------------------https://medium.com/@kavoshex/raspian-added-su...4-bit-kernel-6cf27c2b26db I changed to 64bit at first for Rosetta@home, later OpenPandemics was added without any change….. [Edit 1 times, last edit by mgpointner at May 25, 2020 3:25:11 PM] |

Yes I did the same and it works. For the sake of completion regarding the original issue, I was able to run Rosetta@Home simultaneously by adding the following code to cc_config.xml: <options> |

I installed Raspbian Buster and followed the steps to upgrade to 64 bit. BOINC was still reporting a 32 bit ARM processor. In order to run both WCG and Rosetta, I need to add the alt_platform tag below to the cc_config.xml file
<alt_platform>aarch64-unknown-linux-gnu </alt_platform> Not sure why BOINC was still reporting Buster as 32 bit...but appears to be working. Would be a whole lot easier if WCG just had the OpenPandemics supporting ARM 64 platform aarch64-unknown-linux-gnu directly. |
