Our August 2019 maintenance ( https://blog.pace.gatech.edu/?p=6511 ) is complete one day ahead of schedule! We have brought compute nodes online and released previously submitted jobs. Login nodes are accessible and your data are available.
As usual, there are a small number straggling nodes we will address over the coming days.
- (Complete) Network connections to PACE-RTR will be upgraded. Connectivity in and out of the Rich Data Center will be disrupted on Friday morning. VAPOR network will not be affected.
- (Complete) Additional space will be configured for license server.
- (Complete) OS and application patches will be applied to Red Hat Enterprise Linux (RHEL) 7 servers, effectively upgrading to RHEL 7.6.
- (Complete) OS and application patches will be applied to testflight nodes, to begin testing new versions of kernel and libraries.
- (Complete) PACE management scripts and utilities will be upgraded, to improve reliability and performance.
- (Complete) The submit filter for jobs on the RHEL 7 clusters will be modified to allow proper formatting of commands. This filter is not needed on RHEL 6 clusters.
- (Complete) Upgrade DNS appliances; no downtime is expected due to redundant configuration.
