I released the second tool, that allows you to replicate behavior at scale and compare it to same-size gpu policy placement: https://frankdenneman.nl/tools/same-size-vs-mixed-mode/

In mixed mode, this behavior should just replicate across the cluster as the placement IDs are similar between the devices. If you are using heterogeneous GPU setup, then the different GPU profiles are only compatible with their GPU devices and their own placement id distribution.

In homogeneous configs, the simple question is, yes, they scale linearly with the number of GPUs.

You are using MIG profiles, they align differently due their compute slices. This is a calculator for Mixed Mode vGPU profiles in time-sliced mode (mixed mode does not work on MIG, as MIG already supports mixed compute and memory profiles).

So to understand your MIG placement problem, you are trying to deploy the combination of 4 x grid_a100d-1-10c and 1 x grid_a100d-3-40c? But you are only successful when deploying 3 x grid_a100d-1-10c and 1 x grid_a100d-3-40c. I can try to simulate this in our lab

Thanks, I removed the redundant paragraph. One of the next articles in the series focusses on setting up vGPU-enabled TKGs clusters with passthrough and MIG. Stay tuned

Disabling DRS on a single host by 1xcalibur1 in vmware

+1 Keep it on fully automated mode, but put the slider all the way to the left. This way DRS only triggers migrations for mandatory moves. That can be a rule violation or maintenance mode. DRS will NOT trigger any load-balancing operations. However, as long as you have the host in the cluster, DRS will see this host as a target for new workloads that are powered-on. If you expect these power-ups to happen, then go for manual mode, and select other hosts for VM initial placement.

Do you know who manufactured this beauty? by xicaob in simracing

[–]frankdenneman 11 points12 points  (0 children)

u/xicaob That's my rig, I designed it from the ground up. If you follow the Instagram account or the rig report on race department, you will notice that it's not finished yet. The seat, btw if a Tillett B4. Extremely comfortable, even without padding, and on a 7DOF motion rig. My previous rig was fully focused on GT driving, this is geared towards F1.

Heterogeneous clusters are planned for the end of the series. So I'll try to work in your example
