Qlustar Feature Update 06/23
by General announcements about Qlustar 15 Jun '23

15 Jun '23

A number of new Qlustar features were completed recently and published together with the latest security updates. Version 13.2.0 further improves QluMan with the addition of: - An informative HOST OVERVIEW TABLE [1]. It provides a tabular overview of all the hosts in a cluster split by networks. Tabs at the top allow to select the network one is interested in. In each tab, the IP ranges allocated in the chosen network are shown at the top and a list of hosts with their most important config parameters below. An on-the-fly string/regex filter can be applied to the lists restricting the view to the hosts matched. - New GUI options to fine-tune the LDAP PASSWORD POLICY [2]. This makes it easy to control user password quality and protection against brute-force attacks with appropriate settings. - The possibility to ASSIGN A LUSTRE LNET NAME [3] to the network adapters of nodes and generate a new config file to bring up LNet during boot of Lustre nodes. - The automatic creation of a new configuration file during boot that lists a node's QluMan Generic Properties and their values. This allows to use freely definable Generic Properties as a general key/value store in customization scripts on Qlustar nodes. AlmaLinux was updated to version 8.8 with this release.

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.
