[Resolved] Temporary Network Interruption

This entry was posted by on Monday, 15 October, 2018 at

We experienced a failure in the primary InfiniBand subnet manager that may have impacted both running and starting jobs.   The malfunction happened in such a way that the backup IB subnet manager (SM) didn’t notice the primary was failing to operate normally. We disabled the primary SM, and the secondary SM took over as designed. The service outage lasted from 12:56pm to 01:07pm today, October 15, 2018. PACE staff will continue to investigate this failure mode and adjust the procedures to help prevent it in the future.  As this brief network interruption may have impacted the running and starting jobs, please check your jobs to identify if there are any crashed jobs and report any problems you may notice to pace-support@oit.gatech.edu
