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.

Qlustar Feature Update 01/22
by General announcements about Qlustar 10 Jan '22

10 Jan '22

A number of new Qlustar features were completed recently and published together with the latest security updates. QluMan 12.0.6.0 has the following new capabilities: - QLUMAN TIMERS [1] present a new Config class assignable to nodes. They allow for time-based execution of commands on nodes and are easily configured via the GUI. - ENHANCEMENTS OF THE SLURM GUI COMPONENT [2]: * Added on-the-fly job filtering and job grouping. * Significantly improved mechanism to transfer job data. The QluMan GUI is now able to smoothly handle thousands of jobs. - HARDWARE DETECTION INFO for nodes in the GUI Enclosure view [3] now transparently highlights misconfigurations, helping admins to track down faulty settings. - FILTERS IN USER/GROUP MANAGEMENT [4] have been added, making LDAP management a lot clearer and easier to follow. Other new features: - MELLANOX OFED [5] drivers and tools have been included for optimized support of clusters with newest Infiniband (IB) technology. Qlustar now automatically detects whether IB adapters supported by the current Mellanox OFED release are present and activates its drivers if that's the case. For all other IB hardware, the in-kernel drivers are used. - GPU DIRECT RDMA [6] support has been added for nodes running Nvidia GPUs together with IB adapters supported by Mellanox OFED. It provides a significant decrease in GPU-GPU communication latency and completely offloads the CPU, removing it from all GPU-GPU communications across the network. - The VIRTUALGL image module is now production ready. When used in a node image, Qlustar can provide 3D remote visualization on nodes with the required hardware.
