[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.

[Qlustar-Announce] 11.0.1 adds UEFI support and CentOS 7.8
by General announcements about Qlustar 03 Jun '20

03 Jun '20

The Qlustar team is happy to announce the immediate availability of Qlustar 11.0.1 for download [1]. This minor release has two new features: a) Full UEFI support for the Qlustar installer and PXE booting of nodes. b) The move to CentOS 7.8 as the new supported minor CentOS 7 version. The Qlustar installer now transparently supports installation on legacy PC BIOS hardware as well as machines running under UEFI. If you have the choice, we recommend using the UEFI mode on your hardware. Our PXE booting mechanism has been doubly revamped: Firstly, we use GRUB as the boot loader now per default and secondly, we fully support UEFI based hardware transparently. So it will not matter whether your hardware runs under UEFI or PC BIOS, it should just boot fine, once registered correctly under QluMan. Reverting to booting with PXELINUX on PC BIOS machines is supported if needed/desired. Please follow the special update instructions [2] of the latest security announcements when updating and if you use QluMan singularity images, make sure you download [3] the latest version. This is the last feature addition to Qlustar 11. We now work at full steam on the Qlustar 12 release based on Ubuntu 20.04 and scheduled for some time later this year.
