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. 64-bit Raspbian doesn't even exist! There is only a 64-bit kernel that then allows you to run systemd-nspawn to create a 64-bit OS inside of Raspbian (see raspbian-nspawn-64)... https://www.raspberrypi.org/forums/viewtopic.php?t=257767 BTW, I tried to get a 64-bit kernel on Stretch instead of Buster, and my Pi wouldn't boot. As was 100% expected, the following commands still returned 32-bit when running the 64-bit kernel on Raspbian Buster... (1) file /usr/bin/boinc (2) file /var/lib/boinc/projects/www.worldcommunitygrid.org/wcgrid_opn1_autodock_7.17_arm-unknown-linux-gnueabihf Can anyone else confirm that Rosetta is correctly running on Raspbian on a Pi? This is shocking to me! If you use the file command on Rosetta executable, is it 32-bit or 64-bit? Perhaps Rosetta is running in some kind of container just like raspbian-nspawn-64? Also, has anyone gotten WCG to run on 64-bit Ubuntu Server on a Pi? - https://ubuntu.com/download/raspberry-pi - https://boinc.berkeley.edu/wiki/Installing_BOINC#Ubuntu_2 I tried with Ubuntu Server 20.04, but none of the packages in the 2nd link exist for this OS version.

The process very much depends on homogeneity to the max. |

I did run Rosetta on Raspbian, following these directions:
----------------------------------------https://www.element14.com/community/people/ga...ettahome-on-raspbian-pi-4 However I wasn't able to run four tasks at the same time on my 4Gb Pi4 (after a short while one of the tasks was kicked out due to insufficient memory) and I didn't feel like dealing with possible compatibility issues either, so I switched to WCG. In hindsight maybe running Raspian Lite or DietPi and/or setting up a proper swap space on an external drive could have made things go smoother, I'll give it a try if and when I get another Pi.

Can say so much, Rosetta and the version that runs MIP1 here at WCG has always been 32 bit. The process very much depends on homogeneity to the max. Thanks! I assumed Rosetta@home was actually running a 64-bit executable because it only wants a 64-bit platform! Why does it require "aarch64-unknown-linux-gnu", and why does only "Linux running on 64-bit ARM" appear in following link? https://boinc.bakerlab.org/rosetta/apps.php Perhaps these questions are for another forum! Anyway, good to know that Rosetta (or anything similar like MIP) are always 32-bit. Edit: I just ran the following file command on my macOS, and it returned 64-bit. So, my original question stands: how does a 64-bit executable run on Raspbian? Must run inside some self-contained box ?? file '/Library/Application Support/BOINC Data/projects/boinc.bakerlab.org_rosetta/rosetta_4.09_x86_64-apple-darwin' [Edit 2 times, last edit by poppinfresh99 at May 28, 2020 2:51:25 PM] |

In recent past, one science app misidentified as 64 bit but really ran as 32 bit so techs had to recompile.

Search, 5 seconds, https://www.worldcommunitygrid.org/forums/wcg...ead,41914_offset,0#617488 Well, Rosetta@home is identifying as 64-bit, providing a 64-bit executable (see results of file command), and successfully running on my macOS, so is your link relevant? My Pi running Raspbian doesn't have enough RAM to download the executable, so I can't experiment, so I'm curious if the executable is 64-bit, and, if so, is it some kind of container for 32-bit code. If your search takes 5 seconds, expect results that are worth 5 seconds. |

This is because 64-bit applications include 64-bit instructions that will not be recognized by a 32-bit processor."  [Edit 2 times, last edit by mgpointner at May 29, 2020 4:32:09 AM] |

For those running headless, I wonder what the point of installing Raspberry Pi OS Lite 64-bit would be over just installing Debian 64-bit for arm64.
