- Comparison to SGE solution (see mail from Daniel G.)
   - SGE works with AR ID, proposal from Poznan relies on
     DRMAA2 interface concept
   - Lot of similarities resp. mappable concepts
     (e.g. start time / duration vs. start time / end time)
   - SGE has more of a dictionary approach - 'everything is requestable'
   - Restricting this through a portable 'reservation template'
     would be ok
- Slot concept in both proposals
   - Configured per host, usually express number of concurrent processes
   - Available slots often map to core count, but ultimately it is a
     administrator decision
   - SGE has slots per queue / host / ..., depends only on configuration
- Overall agreement that advanced reservation happens before job 
template creation
   - Both rely on similar resource allocation attributes
     (e.g. candidate hosts, OS type)
   - User submits advanced reservation and then submits jobs to it
   - Separate DRMAA AR data structure beside job template needed
   - needs to become part of the session persistence concept
   - needs to have separate nativeOptions attribute (e.g. for qrsub)
   - Donation of reservation to other users not widely supported,
     left out in DRMAA

Best,
Peter.
