reboot the ADAPT Windows VMs after the implementation of the "Microsoft
Patch Tuesday" updates released every second Tuesday of the month.

Discover Users: When creating a ticket to report a Discover job crashing, if
possible please include the job ID.  This will greatly enhance our ability
to diagnose the problem.  Thank you.

The MATLAB licenses on discover are in high demand.  If you are not actively
using MATLAB on the ineractive nodes, please exit your session so that
other users may use the local licenses.
