Biowulf Cluster DOWNTIME Saturday Aug 6 (Biowulf)Date: 03 August 2011 09:08:54
From: steven fellini (sfellini@NIH.GOV)
For the final phase of the transition of the data center to the Continuous Power System, ALL COMPUTE NODES in the Biowulf Cluster will briefly be powered down. This means that ALL RUNNING JOBS WILL BE TERMINATED. Queued 'swarm' jobs will also be terminated. Jobs will be terminated around 8 am Saturday morning. We hope to have batch resume running jobs on some nodes by noon. Email will be sent to Biowulf users when all nodes are back on-line. We expect to have the Biowulf login node and all storage systems (/home, /data) available during this time. You may also submit jobs (although they will not run until batch scheduling is resumed). We apologize for the interruptions of the past few weeks, but this should be the last one and the new power system will allow for the continued growth of the cluster as well as higher reliability in the face of power grid fluctuations.
