it looks like my device isn't being detected. A Raspberry Pi 4, 4gb ram and 64 GB sd card with Ubuntu 64 bit version. I followed the instructions. Where could I have gone wrong?

it looks like my device isn't being detected. A Raspberry Pi 4 I never got my hands on a Pi. But if you need help with BOINC it's always a good idea to post the full startup messages.I followed the instructions. What instructions? |

"device isn't detected", one requirement for some was to add a platform line to the cc_config.xml which aarch is communicating. Several posts mention resolving the issue for them: <alt_platform>aarch64-unknown-linux-gnu </alt_platform
----------------------------------------Event log copy posting is standard part of the requirement to report issues with the client. [Edit 1 times, last edit by Former Member at May 30, 2020 11:03:53 AM] |

Did you get it to work? With 64 bit ARM?
----------------------------------------One problem with WCG is that they do not have the standard BOINC applications page, where it lists the actual apps, and their architecture/OS combinations supported. For example, the system requirements "help" page just says yes/no for linux. In what world is that helpful?  |

During the last couple of weeks I setup several RPi for the OPN1 project.
----------------------------------------1/ Ideally fresh OS installation (Raspian or the newly released Raspios), otherwise, at least: sudo apt-get update Optional, however I recommend to do following: sudo rpi-update This command will update the firmware and enable the most recent kernel version: currently 5.4.44. Afterwards reboot: sudo reboot 2/ Boinc installation sudo apt-get install boinc 3/ Configure boinc Enable remote access: sudo nano /etc/boinc-client/remote_hosts.cfgAdd the remote hosts authorized to access remotely to RPi's Boinc. sudo nano /etc/boinc-client/gui_rpc_auth.cfgDefine the password for accessing boinc-manager (password is stored unencrypted). 4/ If the graphical interface is installed on the RPi, you shall log to the RPi and invoke the boinc-manager and add WCG to the supported project. Otherwise, if you have a PC available with Windows or Linux with Wine, you can use BoincTasks to manage your boinc nodes. Alternatively, if no graphical interface is installed on the RPi, after login, you can invoke boinc-manager over the command line (CLI). After a couple of minutes, the newly installed RPi shall be registered on WCG. 5/ Log on the WCG web site. Go to device manager and verify that the RPi is properly registered. Select and configure a profile for the RPi device; currently only OPN1 is supported for Raspian/Raspios device ! Depending of the RPi, a WU will take: - about 27-29 hours on a RPi 2 - about 17-19 hours on a RPi 3 If the RPi does not have an active cooling (ventilator), I would recommend to enable only 3 cores for WCG in order to avoid over-heating and CPU throttling. In this case, I setup the corresponding device profile with enabling only 3 OPN1 WUs simultaneously. Since the WCG feeder works well and the OPN1 required download is limited, the RPi will computes continuously the 3 WUs with only a couple of seconds between 2 WUs: upload, report, download. Additionally, you can install RPi-Monitor on the RPi in order to monitor the CPU load and CPU temperature. RPi-Monitor will be accessible over a web browser at port 8888. Enjoy, Yves --- PS: @all: procedure improvements are welcome  ---------------------------------------- [Edit 1 times, last edit by KerSamson at Jun 12, 2020 8:06:31 AM] |

Until now, I did not make tests with Boinc on an Ubuntu installation on a RPi.
----------------------------------------At the other side, I run boinc on Ubuntu / LinuxMint on all my Linux-based machines; but it is another story. |

Does any of that work with 64 bit ARM & OS (aka aarch64)?

Someone posted a link to benchmarks between 32-bit and 64-bit userland/kernel, and on the same device, the 64-bit yielded faster performance. I'm looking forward to the "Lite" version of Raspberry Pi OS 64-bit coming out and full USB3 boot support instead of microSD card. And heck, if I can just use the aarch64 Debian net-installer image instead of Raspberry Pi OS, I'll happily do that.

Only RPi 4 is able to run 64 bit operating system.
----------------------------------------However RPi 4 with 8 GB can run 32 bit operating system and applications. The limitation if only 3 GB RAM per application, nonetheless the 8 GB RAM can be allocated by the 32 bit OS. The OS version with USB boot capability is currently still a beta version. I would probably wait a little bit before starting to use it, in order to avoid residual bugs. On my side, I have only RPi 1 B+, RPi2 and RPi 3 at this time. As soon as the USB boot feature will be finalised, I will buy RPi 4, maybe trying to build one of the mentioned clusters. Cheers, Yves |
