Compute Farm Reduced Capacity: 23-Aug-2021 to 25-Aug-2021

Starting Monday, 23-Aug-2021 @ 8:00 AM, most CLASSE Compute Farm batch queues will be disabled in advance of a Wilson Lab East Module power outage on Wednesday, 25-Aug-2021. Please note that interactive and CHESS queues are excluded from this two-day pre-outage pause; jobs running in these queues will instead be terminated early morning on Wednesday, 25-Aug-2021, when the East Module power is cut. Power is expected to be restored by midday.

Any terminated jobs can be resubmitted immediately to the "all.q" and "interactive.q" queues for continued processing throughout the power outage. This continuity of service is made possible by two new farm nodes that have been deployed in Wilson 221. However, farm capacity will be severely degraded, so you may need to wait for resources to become available before your job is scheduled.

NoMachine Update: Tuesday, 24-Aug-2021 @ 10:00 AM

On Tuesday, 24-Aug-2021, at 10:00 AM, all NoMachine servers will be updated to the latest minor point release. When this update occurs, any remote sessions will be disconnected and any virtual desktops will be terminated. The update to each server will take a minute or two, after which you will be able to reconnect to the physical display and create new virtual desktops as usual.

Linux Kernel Update: Tuesday, 24-Aug-2021 @ 10:00 AM

On Tuesday, 24-Aug-2021, the latest Scientific Linux 7 (SL7) kernels and NVIDIA drivers will be pushed to all CLASSE SL7 boxes. Please reboot your Linux computers after Noon to pick up the updated kernel and drivers.

Pritunl Server Outage: Thursday, 26-Aug-2021 @ 12:00 Noon

On Thursday, 26-Aug-2021, at 12:00 noon, there will be a brief outage of the new CLASSE VPN service, Pritunl, for a server update. Please submit a ServiceRequest if you have any questions or concerns.

AppsAnywhere Upgrade: Tuesday, 31-Aug-2021 @ 10:30 AM

On Tuesday, 31-Aug-2021, from 10:30 AM to 11:30 AM, the AppsAnywhere service will be unavailable for a Cloudpaging server upgrade. During this time, any applications that are active might report that there is an interruption; they will resume when the connection returns. Applications that are "offline allowed" will not be affected. If you have any questions or concerns, please submit a ServiceRequest.

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.
