Dear Seaborg users,
Several changes to the Seaborg LodLeveler class structure will take
place on Tuesday, January 18:
- The current premium classes will be consolidated into a single class
with a relative scheduling priority of 3 (next in line after the
interactive and debug classes). Its wall limit will be 24 hours.
- The maximum number of nodes that can normally be requested will be
299. A new class (reg_300) will be created to accommodate requests for
300 or more nodes. This class will usually have a run limit of zero and
special arrangements will have to be made to run jobs of this size. The
consultants will contact users who submit jobs to this class.
- The reg_128 class is no longer being used and will be retired. It
will be replaced by a new class, reg_256. At some time in the future
jobs submitted to this class will receive some scheduling assistance.
This is still being worked on, and for now reg_256 will have the same
relative priority as reg_32 and reg_48.
