Research Computing Shared Computing Cluster (SCC) Downtime – June 10 – 12, 2019

Friday, June 7th, 2019

Posted in General News, Incidents, Info Messages, Uncategorized

The Research Computing Shared Computing Cluster (SCC) and related services have been returned to normal operation ahead of schedule, following the successful completion of the scheduled MGHPCC annual maintenance.

Previous Update

The Shared Computing Cluster (SCC) will be offline June 10-12 while the Massachusetts Green High Performance Computing Center (MGHPCC), which houses the SCC, undergoes scheduled annual maintenance. During this time, the SCC operating system will be upgraded to CentOS 7. RCS will hold Walk-in Consulting Hours to assist with migrating your workflow to CentOS 7. The planned outage is scheduled to last until Wednesday at 12 noon; we will let you know if the work is completed early and the systems are available for use sooner at http://www.bu.edu/tech/support/research/whats-happening/updates/.
  • Downtime: Monday, June 10 at 9 am to Wednesday, June 12 at noon.
  • Systems Impacted: SCC (login and batch nodes, home directories and project disk space), Linux Virtual Lab (scc-lite.bu.edu), class.bu.edu, and ATLAS.
  • Queue Draining: The SCC scheduler will not dispatch jobs that have specified a runtime that extends beyond June 10 at 9 am. These jobs will remain pending and will run under CentOS 7 when the system returns to normal operation on June 12 at noon.
Upgrade to CentOS 7: Please see the CentOS 7 Transition pages for detailed instructions on what you need to do to make sure your jobs run correctly after the upgrade.
