[slurm-users] Heterogeneous GPU Node?

 Hello all,

Slightly OT, but I'm hoping the hive mind here can share some advice.

We have a GPU node with three RTX8000 GPUs installed. The node has a
capacity of 8 cards in total. I have a researcher who possibly wants to add
an A100. I recall asking our vendor a while back whether it's possible (or
advisable) to add that card to the existing node, which would result in a
heterogeneous mix of GPUs in a single system. They indicated that it's not
recommended to do so, but I'm wondering whether anyone has direct
experience with this.

And, apropos of this list, if it's fine to move forward with this, are
there any Slurm configuration issues I should be aware of?

Warmest regards,
