Dear Franklin Users,
Franklin will have a system maintenance tomorrow (Wed, Dec.5) from
7-11am, PST. The default wallclock time of 5 min for production queues
will be effective after the maintenance. Please be sure to check your
batch scripts to prevent your jobs from exiting prematurely. Note:
Jobs currently in the queue are not affected by this change, and should
be getting the max wallclock limit as default (12 hrs) if is it not set
explicitly.
The run limit for the "interactive" class will also be decreased from 2
to 1 at tomorrow's maintenance.
Best Regards,
Helen He
