A downtime for Ruby only is scheduled from 8 a.m. to 5 p.m. Thursday,
July 6, 2017. The downtime will only affect the Ruby Cluster.
All other clusters, web portals, and HPC file servers will
not be affected.
In preparation for the downtime, the batch scheduler on Ruby will
begin holding jobs that cannot be completed before 8 a.m., July 6.
Jobs that are not started will be held until after the downtime
and then started once the system is returned to production status.
