Do you happen to know how does one access/use those A100 cores? | ||

No. The problem is that you can't migrate threads between cores with different vector length. The current ubuntu 26.04 image, that is installed, lists 16 cores in htop, but you can only run applications on the first 8 (e.g. taskset -c 10 fails). If you query whats running on the A100 cores you see things like a "kworker" processes. I suspect that it should be possible to write a custom kernel module that runs on the A100s with the current kernel, but I'm not sure. I expect it will definitely be possible to boot a OS only one the 8 A100 cores. Well have to see if they manage to figure out how to add support for explicitly pinning user mode processes to the cores. The ideal configuration would be to have everything run only on the X100s, but with an opt-in mechanism to run a program only on an A100 core. | ||
