[Mauischeduler-users] Special nodes

[Scott W. <swe...@ph...>]

I have a situation with our cluster where we have a limited number of
USB hardware keys required to run a certain piece of software.  What
I'd like to be able to do is plug the key(s) into a node or two, flag
that node with some "HAS_KEY" identifier, and then get the scheduler
to put jobs that require that key onto those nodes only.  These
special nodes would be used for non-special jobs when there were no
other regular nodes available...

Is this possible/easy?  I'm a bit new to maui, but have poked around a
bit and can't seem to figure it out.  I keep seeing references to this
sort of thing on supercluster.org/clusterresources.com but I take it
this is some sort of commercial scheduler that uses maui?

Any advice or just a point in the right direction would be great!

Thanks,

Scott Webster

PS I think we're running version 1.23
