The Qlustar team wishes you all the best for the new year and is pleased to announce the immediate availability of Qlustar 12.0.0 for download [1]. It updates Qlustar's core platform to current Ubuntu 20.04 LTS. The CentOS [2] edge platforms remain based on 7.9 (with integrated OpenHPC [3] 1.3.9) and 8.3 (OpenHPC 2).
The highlight of this release is the move to LDAP as the user and group name service, replacing the NIS setup used earlier. A fully configured LDAP instance is created at installation time. Net-boot nodes may directly authenticate users against this instance or use conveniently synced flat passwd/group files when scalability is critical.
QluMan has a new optional component [4] to manage the Qlustar LDAP instance. It consists of a User and Group Management interface, as well as a powerful tool to import users/groups from passwd-like flat files.
The second major new QluMan feature is the ability for easy and clean integration of external LDAP or Active Directory services with the new Nameservice Providers [5] and Nameservice Configs [6] dialogs.
Finally, the QluMan GUI has been ported to the current QT 5 toolkit. This was a huge 'under the hood' effort that ensures the long-term maintainability of QluMan and also improves its stability.
Highlights among the various major component updates include Kernel 5.4.x, Slurm 20.02.x, CUDA 11.0, ZFS 0.8.5 and BeeGFS 7.2. Please read the release notes [7] for more details.
