Nice work!

Just to be clear, at the moment, one cannot set an attribute in the queue
configuration (or the server¹s nodes file) for GPUs, but only in the node¹s
mom_config file? I couldn¹t find anything in the source to support something
similar to setting resource attributes for a node:       set node bh001 gpus
= $

As for the second part about qrun (this may be a question for the maui
list...), is it necessary to use the qrun to manually run a job with a
nodes=$:ppn=$:gpu=$ in the resource listing? I was under the impression that
using GRES (in Maui) could support this type of functionality, at least in a
limited way.

Sorry rather basic questions, we¹ve just gotten some GPUs in, and we¹re
working to integrate them with the rest of our cluster as seamlessly as
