Qlustar Feature Update 07/21
by General announcements about Qlustar 17 Jul '21

17 Jul '21

A number of new Qlustar features were completed recently and published together with the latest security updates. QluMan 12.0.3.1 has the following new capabilities: - PRE-SYSTEMD NODE CUSTOMIZATION has been introduced via a new config class [1]. Files and scripts placed in a particular path may be transferred to the booting node, and scripts being subsequently executed. This is a powerful and flexible new dynamic node customization feature. - ACTIVE DIRECTORY USER IMPORT into the Qlustar LDAP server is now possible via the GUI [2]. This allows for an AD integration without compromising HPC features also on large clusters. - QLUMAN MONITORING 1.0: This is the first milestone of the upcoming new Qlustar monitoring architecture [3] eventually replacing Nagios. It implements a filesystem-based check/trigger mechanism controlled by QluMan execd. First usage example: Start slurmd only once checks are successful and drain/undrain if they fail/recover later. - Support for DHCP-less boot (see below). - SUPPORT FOR ROUTED NETWORKS as primary boot networks and in NetworkFSMounts was added. Other new features: - Update from CENTOS 8.3 to 8.4 with integration of OPENHPC 2.3. - DHCP-LESS BOOT: DHCP is now only used during the initial BIOS/UEFI/PXE stage. All necessary node configuration data previously provided by DHCP is now provided via QluMan in the pre-systemd boot phase. - To control user access by ssh on slurm nodes, a new UNIX group _node-ssh_ was introduced. Members of this group are always allowed to ssh into a node, even without slurm job. - A new image module VIRTUALGL was added for experimental usage. Using it in a node image, Qlustar can provide 3D remote visualization on nodes with the required hardware.

[Qlustar-Announce] Happy new year with Qlustar 12
by General announcements about Qlustar 09 Jan '21

09 Jan '21

The Qlustar team wishes you all the best for the new year and is pleased to announce the immediate availability of Qlustar 12.0.0 for download [1]. It updates Qlustar's core platform to current Ubuntu 20.04 LTS. The CentOS [2] edge platforms remain based on 7.9 (with integrated OpenHPC [3] 1.3.9) and 8.3 (OpenHPC 2). The highlight of this release is the move to LDAP as the user and group name service, replacing the NIS setup used earlier. A fully configured LDAP instance is created at installation time. Net-boot nodes may directly authenticate users against this instance or use conveniently synced flat passwd/group files when scalability is critical. QluMan has a new optional component [4] to manage the Qlustar LDAP instance. It consists of a User and Group Management interface, as well as a powerful tool to import users/groups from passwd-like flat files. The second major new QluMan feature is the ability for easy and clean integration of external LDAP or Active Directory services with the new Nameservice Providers [5] and Nameservice Configs [6] dialogs. Finally, the QluMan GUI has been ported to the current QT 5 toolkit. This was a huge 'under the hood' effort that ensures the long-term maintainability of QluMan and also improves its stability. Highlights among the various major component updates include Kernel 5.4.x, Slurm 20.02.x, CUDA 11.0, ZFS 0.8.5 and BeeGFS 7.2. Please read the release notes [7] for more details.

[Qlustar-Announce] OpenHPC 2.0/CentOS 8.3 on Qlustar 11
by General announcements about Qlustar 22 Dec '20

22 Dec '20

The Qlustar team is pleased to announce the immediate availability of OpenHPC 2.0 [1] on top of CentOS 8.3 as an update to Qlustar 11. You can migrate your existing images and chroots to this new release in the usual way [1]. New ones can be generated via QluMan. Note that the disappearance of CentOS [3] as we knew it in the past, will not have a negative impact on Qlustar users running CentOS based nodes. There will be a simple migration path to whatever new RHEL compatible distribution will turn out to be the best choice at the end of 2021. Migration will involve nothing more than a usual Qlustar security update.
