1) Message boards : Projects : Dedekind@Home, anyone ?
Message 113148
Posted 20 Nov 2023 by magic_sam 		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

Looks like a job for BOINC IMHO :)

Opinions ?

Posted 8 Oct 2023 by magic_sam 		Dear all,

Is there a need for a new BOINC project to accommodate this ?

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:

Posted 15 Feb 2023 by magic_sam 		I just installed both OpenCL implementations (ROCr and legacy), still no luck:

How could I be sure which implementation is used ?

7) Message boards : GPUs : Can't get the AMD Radeon RX 7900 XTX to crunch for BOINC projects on Ubuntu 22.04 LTS
Message 111073
Posted 15 Feb 2023 by magic_sam 		This is where I downloaded the drivers: https://www.amd.com/en/support/graphics/amd-radeon-rx-7000-series/amd-radeon-rx-7900-series/amd-radeon-rx-7900xtx

I followed these instructions: https://amdgpu-install.readthedocs.io/en/latest/

There are two OpenCL implementations available: ROCr and "legacy": https://amdgpu-install.readthedocs.io/en/latest/install-script.html#specifying-an-opencl-implementation

Should I give the "legacy" one a try ?

Posted 15 Feb 2023 by magic_sam 		Thank you @Jord for copying the error output to this thread :)

There are two platforms showing in "clinfo": I believe they are the Radeon RX 7900 XTX GPU and the embedded GPU part on board the Ryzen 9 7950X, right ?

https://www.amd.com/en/products/graphics/amd-radeon-rx-7900xtx
https://www.amd.com/en/product/12151

One thing I find odd in the "clinfo" output: "max compute units" is half what it should be, i.e 48 vs. 96 CU on the GPU, and 1 vs. 2 on the CPU:

Message 111068
Posted 15 Feb 2023 by magic_sam 		Dear Keith,

I upgraded BOINC to 7.20.5 as you told me to and tried to run some Einstein@Home jobs on the GPU.

No luck so far: https://einsteinathome.org/fr/task/1428468904

What am I doing wrong ?

Message 111040
Posted 13 Feb 2023 by magic_sam 		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
