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.

Is it possible to add modules to qlustar linux kernel?
by pierre-yves.boelle＠upmc.fr 20 Dec '22

Hi all, I'm trying to set up Qlustar 12.0 with ubuntu focal on a HP machine equiped with a smart array controller P816i-a. The problem is that the smart array is not recognized after install: I can see it with lspci, but the disks are not listed in /dev. As far as I understand, this is a driver issue : the smartpqi module is required for this smart array. This module is available from "linux-modules-extra" in ubuntu focal 20.04, but this package is not part of the qlustar distribution. So questions : 1 - Is there a way I can simply add a required module (for example .ko file) in the qlustar kernel and simply recompile the qlustar kernel? 2 - failing that, should I expect trouble running qlustar with a "pure ubuntu" kernel ? If I add the focal repository in apt sources and install linux-modules-extra, I can build a new kernel OK, but it is "pure ubuntu" - not qlustar. Is qlustar kernel just a light version of the ubuntu kernel and that's ok? or does qlustar include extra components ? Any input appreciated PYB
