Dear David and Glen,

Thanks for your replies. Let me shortly comment on some aspects.

I looked at the floating resources in Moab, but it does not seem to be smart enough to know that a single user on a single multi core computer can start multiple MATLAB instances while requiring only a single license. So the actually required resource is once license for all jobs in case they all run on a single node, whereas it is one license per job if they run on separate nodes. Since we run many MATLABs in parallel on our 48-core nodes, this distinction is rather important: it is the difference between scheduling for 1 license versus 48 licenses. One of the reasons of having these 48-core nodes is that they allow us to minimize license usage. 

I have also attempted to use dynamic consumable generic resources, but http://www.clusterresources.com/bugzilla/show_bug.cgi?id=118 is stopping me from doing so.

The bin location makes sense on the torque server. But I still don't see why commands that cannot be run on a client (not even by an administrator) would get installed along with the "torque-package-clients".

best regards,
Robert
