ELF is now back in service
Saturday, March 7, 2020 at 2:05 am
Maintenance for the ELF cluster is nearly complete and the system has been returned to service.
Account holders can access ELF at elf.oarc.rutgers.edu or elf.rutgers.edu (ssh [NetID]@elf.oarc.rutgers.edu).
Work completed includes:
— All hosted VMs, compute nodes, and login nodes have been upgraded to CentOS 7.7 with GPFS 188.8.131.52, SLURM 18.08.8.
— The firmware for all managed and unmanaged InfiniBand switches has been upgraded.
— Node Health Check has been setup to help with monitoring of the compute nodes.
— Added DNS names such that elf.oarc.rutgers.edu and elf[1-2].oarc.rutgers.edu and elf.rutgers.edu are the names used.
— Same list of packages is now installed on each node of each type (improved consistency among the compute nodes).
— Switched from nslcd (deprecated) to System Security Services Daemon (SSSD) for authentication services.
— The Lmod module system has been upgraded to 8.1.6.
