Chilled Water Issue from Physical Plant

The HPCC facility is currently experiencing higher than normal temperatures due to some issues with our chilled water supply.  This flux in temperature has required us to shut down the Hrothgar Ivy and West queues to reduce the heat in the room.  Service to these queues will return once the chilled water issues have been resolved.  Thank you for understanding and we are sorry for the inconvenience! 

We expect the Hrothgar West and Ivy queues will return to service on Monday, January 8th.


Maintenance downtime policy for  HPCC systems:

  • Special periods may be reserved for performing routine maintenance. Users will be notified as early as possible when we are planning on bring the systems down for any reason.
  • Systems may also go down at anytime to fix security issues, but every effort will be made to give the earliest possible notice.
  • Maintenance may also be required without prior notice in the event of system crashes or any unstable behavior.

Users should always keep extra copies of any files that are critical to their research on systems that are outside of the HPCC to guard against possible loss in the event of unforeseen catastrophic failure.

This policy is just good general practice and applies to all critical research files, regardless of where they are stored or whether or not they are located on HPCC resources.
