1) Message boards : Projects : Dedekind@Home, anyone ? (Message 113148) Posted 20 Nov 2023 by magic_sam Post: Well, Lennart Van Hirtum is studying at Paderborn University and Christian Jäkel at Dresden University of Technology. What about a collaboration between these two German universities ? How much funding does a BOINC project need, in average ? Some code by Lennart Van Hirtum is already available on Github: https://github.com/VonTum/Dedekind. If Christian Jäkel could contribute his code (based on that paper: https://arxiv.org/pdf/2304.00895.pdf), this BOINC project could offer two applications, one for each algorithm. Opinions ? Best regards, Samuel

3) Message boards : Projects : Announcing the $12k NIST Elliptic Curves Seeds Bounty (Message 112856) Posted 8 Oct 2023 by magic_sam Post: Dear all, Is there a need for a new BOINC project to accommodate this ? https://words.filippo.io/dispatches/seeds-bounty/ https://saweis.net/posts/nist-curve-seed-origins.html Best regards, Samuel
4) Message boards : GPUs : Can't get the AMD Radeon RX 7900 XTX to crunch for BOINC projects on Ubuntu 22.04 LTS (Message 111107) Posted 21 Feb 2023 by magic_sam Post: Dear all, Problem solved :) https://einsteinathome.org/fr/content/cant-get-amd-radeon-rx-7900-xtx-crunch-einsteinhome-ubuntu-2204-lts I had to install the full ROCm package (https://docs.amd.com/bundle/ROCm-Installation-Guide-v5.4.3/page/How_to_Install_ROCm.html) and edit /usr/lib/systemd/system/boinc-client.service: #ProtectSystem=strict ProtectSystem=off Milkyway@Home GPU tasks still refuse to run though, but it appears to be a well known issue: https://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=4885&postid=75074#75074 Best regards, Samuel

10) Message boards : GPUs : Can't get the AMD Radeon RX 7900 XTX to crunch for BOINC projects on Ubuntu 22.04 LTS (Message 111040) Posted 13 Feb 2023 by magic_sam Post: Dear all, I have a new computer dedicated to BOINC, featuring an AMD Ryzen 9 7950X CPU and an AMD Radeon RX 7900 XTX GPU. I'm getting good results with projects like Universe@Home and Asteroids@Home on the CPU front, but so far I've been unable to get the GPU to work with BOINC. The computer is running Ubuntu 22.04 LTS x86_64, and I followed the official procedure to install the AMD drivers: https://amdgpu-install.readthedocs.io/en/latest/ I tried two GPU projects: Einstein@Home and Milkyway@Home, and both failed in similar ways: Error at Einstein@Home: https://einsteinathome.org/fr/task/1423890400 Error at Milkyway@Home: https://milkyway.cs.rpi.edu/milkyway/result.php?resultid=685395746 I believe the drivers are correctly installed, at least "clinfo" is working just fine. I know BOINC complains about the lack of memory in the logs but this is nonsense IMHO: the GPU has 24GB or RAM, and the host itself has over 10GB of RAM available, out of 16GB. What am I doing wrong ? Should I report a bug over at AMD, as per https://amdgpu-install.readthedocs.io/en/latest/install-bugrep.html ? Thank you all in advance for your help :) Best regards, Samuel
