Peregrine System Time January 21, 2019 and downsizing on January 7th, 2019. Peregrine will be retired July 2019.

January 04, 2019

  • We will be turning off approximately half of the computing capacity of Peregrine on January 7th at 1:00pm. This will effectively remove the "batch" queue. Please plan to transition to the "batch-h" queue.
  • Peregrine will be unavailable on January 21, 2019 to allow removal of the end-of-life nodes from the job scheduling software.  The number of nodes available in the "short" and "debug" queue may change after this system time.  Peregrine will return to service early on January 22, 2019.
  • Peregrine will be retired from service at the end of July 2019.
