Dear Hummingbird Users,

Please be advised that we are conducting a short maintenance cycle on Wednesday September 20, 2023 from 6:00am to 7:00am.

During this window, we will be rebooting the cluster login node. At that time, you will not be able to login to the cluster. In-flight jobs will continue, but pending jobs may be disrupted. If you submitted a job before the maintenance window and it was in a pending status, please check to make sure the job properly launched after the maintenance window is announced to be closed. You can still log into hb-feeder to access files and move data, but please log in to that machine directly (not through the login node). Any “screen” or “tmux” (or similar) sessions should be closed manually before the maintenance window begins. Sessions left open will be terminated automatically on reboot.

Please feel free to email hummingbird@ucsc.edu if you have any questions or concerns regarding this maintenance window.
