GitLab Update: Tuesday, 21-Jan-2025 @ 10:00 AM
On Tuesday, 21-Jan-2024, at 10:00 AM, the
CLASSE GitLab will be unavailable for approximately one hour for a series of updates. Please submit a
ServiceRequest if you have any questions or concerns.
NoMachine Update: Tuesday, 21-Jan-2025
If you are a
NoMachine user, at the end of Monday, 20-Jan-2025, please save your work and log out of any NoMachine Virtual Desktops. On Tuesday, 21-Jan-2025, starting at 4:00 AM, all NoMachine servers will be updated to the latest release. When this update occurs, remote connections will be interrupted and all NoMachine Virtual Desktops will be deleted. Please submit a
ServiceRequest with any questions or concerns.
Linux Updates: Reboot Your Computers
A new Linux kernel has been pushed to all CLASSE Linux boxes. Please reboot your computer at your convenience for the updated kernel and drivers to take effect.
Compute Farm Default OS: AlmaLinux 9
As previously announced, we have changed the default operating system for
CLASSE Compute Farm jobs from Scientific Linux 7 to AlmaLinux 9. If you wish to submit jobs to legacy Scientific Linux 7 nodes after this change (for compatibility with any legacy executables), please use the
"-l os_name=el7" flag in your job submission scripts. Otherwise, any submitted jobs will default to running on AlmaLinux 9 nodes. To see a complete list of AlmaLinux 9 nodes (and the queues on those nodes), please type "qhost -q -l os_name=el9".
Please note that after this change,
JupyterHub will also default to AlmaLinux 9 Farm nodes, which might be incompatible with some dedicated CHESS queues that are still running Scientific Linux 7. If you are responsible for any of these queues, please submit
ServiceRequest to schedule an upgrade to AlmaLinux 9.
General network and server maintenance will occur every Tuesday from 12:00 noon to 2:00 PM. The CLASSE-IT group will always announce any expected disruptions in our
NewsLetter and via
CLASSE-IT-NEWS-L, but with the size and complexity of our network there is always the potential for something to go wrong. We will do our best to contain all network maintenance and planned outages to Tuesdays from 12:00 noon to 2:00 PM.
Unless other arrangements have been made,
CLASSE-managed Windows systems may be updated and rebooted on Tuesday morning at 2:00 AM, so please avoid critical or lengthy operations at that time. For more details, please see
SystemExpectations.
