Qlustar Feature Update 03/23
by General announcements about Qlustar 29 Mar '23

29 Mar '23

A number of new Qlustar features were completed recently and published together with the latest security updates. QluMan 13.1.0 highly improves on its Host Filter capabilities: - NEW FILTERS [1] for Property/Config sets, Property/Config types and Property/Config values have been added. These filters make it much easier to select correct groups of hosts for re-configurations or command execution especially on large in-homogeneous clusters. - COMMAND EXECUTION OR HOST SELECTION [2] using filters temporarily defined on-the-fly is now possible directly from the Host Filter dialog. This helps a lot in quickly checking on a group of nodes based on any configuration criteria. The Qlustar documentation has been expanded: - An HPC ADMIN MANUAL [3] has been added. It explains the recently introduced Qlustar HPC Core Stack and gives a detailed introduction to package management using SPACK [4]. - A section about WORKING WITH SPACK [5] has been added to the HPC USER MANUAL [6].

One more present from Santa - Qlustar 13
by General announcements about Qlustar 29 Dec '22

29 Dec '22

The Qlustar team is pleased to announce the immediate availability of Qlustar 13 for download [1]. It updates Qlustar's core platform to current Ubuntu 22.04 LTS. The AlmaLinux [2] edge platform remains based on 8.6 while CentOS 7 [3] is still supported via Qlustar 12 images and the new cross-version compatibility. The highlights of this release are the addition of BMC hardware management via IPMI/Redfish in QluMan, the integration of Spack as the new HPC package manager and the cross-version compatibility between Qlustar releases. QluMan's new *BMC hardware management* support allows for BMC authentification management, power control of nodes via IPMI or Redfish, the display of BIOS settings as well as their validation and correction. A cumulative problem report showing an overview of cluster node misconfigurations has also been added to QluMan. Spack [4] has been introduced as the new package manager for HPC related application software beyond the so-called *Qlustar HPC core stack*. It offers a huge list of supported software packages and by design provides hardware optimized versions of them. The HPC core stack is a new component definition within Qlustar and is related to the introduction of Spack. Rather than aiming to provide as much HPC functionality as possible by OS packages (debs/rpms), the HPC core stack now makes a clear cut between Qlustar related system software which remains provided as OS packages and HPC application software. Starting with this release, *cross-version compatibility* between the current and the previous Qlustar release has been added. In practice this means, that on a cluster with a Qlustar 13 head-node you can still run nodes with Qlustar 12 images/chroots and vice versa. This new feature was added to allow even smoother release upgrades. Highlights among the various *major component updates* include Kernel 5.15.x, Slurm 22.05.x, Lustre 2.15.1, ZFS 2.1.6 and BeeGFS 7.3.2. Please read the release notes [5] for more details.
