Compute Farm Reduced Capacity: Week of 26-Jul-2021 @ 8:00 AM
Starting Monday, 26-Jul-2021 @ 8:00 AM, most CLASSE Compute Farm batch queues will be disabled in advance of the Wilson Lab East Module power outage on Wednesday, 28-Jul-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, 28-Jul-2021, when the East Module power is cut.
Any terminated jobs can be resubmitted immediately to the "all.q" and "interactive.q" queues for continued processing throughout the power outage (likely through Friday, 30-Jul-2021). 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.
CLASSE Network Outage: Tuesday, 03-Aug-2021 @ 9:00 AM
On Tuesday, 03-Aug-2021, from 9:00 AM to 12:00 noon, there will be a general network outage for a central firewall upgrade. Please
save your work to samba (central filesystems) and
log out of your computer before this time. During this network outage, remote access to CLASSE resources and websites will be unavailable. Please submit a
ServiceRequest with any questions or concerns, and consider subscribing to the
classe-it-news-l mailing list for additional announcements and information.
If you have a CLASSE-managed computer, you might occasionally see
legitimate popup windows from our ESET antivirus software. Any other antivirus popups (i.e not from ESET) are
fake. Please DO NOT click on these fake antivirus popups (or otherwise "allow" them do anything). Instead, simply close the popup window (or webpage tab) or log out and log back in. If you are unable to dismiss the popup window, 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.
