Thanks for the explanation!

The AVX512 unit in ZEN5 is supposed to be significantly more powerful than in ZEN4. In my test 7950X vs. 9950X, both 105W ECO, the 9950X was only as fast the 7950X, often even 1-2 minutes slower. Same with Windows 11 (with new AMD patch) as with Linux Mint 22, . Does the app for ZEN5 require special optimization or do the improvements simply not work for BOINC projects?

NFS@Home also has an AVX512 app. It behaves the same there.

Do period search 102.20 (win10) use AVX512? All apps hat AVX, SSE and so on in their names but 102.20 does not.

Do you use something like this to run CUDA code on AMD GPUs?

I noticed something else that looks strange.

I am running the new application on a computer with 2 graphics cards (GTX 1070 Ti and GTX 2070).

In BOINC manager it shows 2 GPU tasks running (one on device0 and one on device1 as expected), but when I look at the GPU load using GPU-Z, I see that the GPU Load is 98% for the GTX 2070, but always 0% for the GTX 1070 Ti.

The workunits are completing successfully, but it doesn't look like the GTX 1070 Ti is actually being used.

I am using Windows 10 Professional with latest updates, BOINC Manager 7.14.2 and NVidia driver v445.75

I have tried resetting the project, but this didn't help.

Edit:
I just tried it on another computer with 2 GPUs (two identical GTX 760 cards) and the same thing is happening.
Even though BOINC manager shows 2 GPU tasks running, I only see load on 1 GPU.


Same problem here with GTX 970 and 1660 Super.
I had the same issue with 2 Radeon at Moo! Wrapper some month ago and never found a solution.
