Network maintenance 2-4pm Tuesday October 4

From 2-4pm Tuesday, October 4, there may be periodic network glitches as we update the configuration on our core network infrastructure.

Matlab on Linux

On Tuesday at 10am, we will update the default version of matlab on Linux to 2016a. All previous versions will still be available using the -r flag (for example, "matlab -r 2012a"), but if you just type "matlab" you will pick up the latest release.

For more information on matlab at CLASSE, please see MatLAB .

CHESS DAQ Upgrade and Rotation

On Tuesday at 10am, we will upgrade the main CHESS DAQ filesystems to new hardware and prepare them for the 2016-3 run. When this upgrade is complete, most clients that access the filesystems through NFS will need to be restarted.

At this time, the 2016-1 data will be removed from disk. Data can be kept on disk or restored at any time through an email to service-classe@cornell.edu.

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.
