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.
