I am able to schedule gpus with torque as long as I dont use maui as
scheduler, because it will just not start the jobs when gpus are

We are using Gromacs with openmm and it takes a paraemter with the
index of the gpu on which it should start running. It feels very
comfortable to use the PBS_GPUFILE as an indexer. The problem is that
we'd like to use fairshare within our scheduler, and torque-sched will
not provide it.

Do you know if there is any workaround to get maui+torque scheduling gpus?

I have googled for a while and so far, every result makes tend believe
that it does not work.
