OGF28
- Queues added

- Parallel job support added
- Monitoring
- Dropped core monitoring -- doesn't really help
- Useful for monitoring, but not for job submission information
- Project identifier
- Rejected file purging facility
- Job Template
- Min memory
- Machine arch
- Candidate nodes
- Advance Reservation
- Sampling rate for implementing "relaxed reservations" is an implementation detail
- Make the duration optional -- solves the relaxed reservation issue
- Rejected merging job info into job template
- Job info is now a value type
- Job Info
- Relaxed master/slave node list symatics
D-Grid
- Mostly PBS, SGE, and Torque
- Want core file management
- Pre-jobs to prepare for execution fits well with DRMAA wait operations
- Want to know when it will be support in product releases
- Make sure monitoring is compatible with Globus
Queues
- The list of queues is not programmatically useful.
- It must be interpreted by an end user
- Adding queue list supports the portal-building use case
- Majority is for adding the queue list to the monitoring interface
- Explicitly adding portal-building as main use case
- Queue names are explicitly opaque
- Slots and wallclock are to return the bounded set of valid job template attribute input values
