Assuming the GPUs within a node are all of the same type, could you define
a feature for each GPU type, assign the features to the appropriate
nodes, and then run the job with

   --contraint=gpu_TypeA  --gres=gpu:1

?

This is obviously rather clunky and it would be much nicer if
multiple GPUs types passed to '--gres' were ORed.

Cheers,

Loris
