The Qlustar releases 12.0.0.1-b528f1339 and 11.0.1.5-b527f1338/40 are ready
including a number of security and bug fixes. Please check the following
web pages for details about security fixes and special update instructions:
https://qlustar.com/news/qsa-0118211-linux-kernel-vulnerabilitieshttps://qlustar.com/news/qsa-0118212-security-update-bundlehttps://qlustar.com/news/qsa-0118213-security-update-bundle
The following non-security related enhancements/bug fixes are included:
Both 11.0 and 12.0 update to
- The latest Nvidia graphics drivers 460.32.03 supporting recently
introduced Nvidia hardware.
- The latest ZFS 0.8.6 fixing a memory management bug.
Fixes for 12.0 only:
- QluMan 12.0.0.39
* Detect IB nics with names other than ib[0-9]
* Fix preserving minimized/maximized state for windows
* Fix cloning of "Network FS Mounts" configs
* Fix kernel options editor for "Network FS Mounts" configs
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.

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.

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.

CentOS 8 support is now available as a third Qlustar edge-platform and
was published together with the latest security updates. It comes with
the same functionality as our CentOS 7 port which includes out of the
box OpenHPC 1.3.9 integration, Slurm 18.10.x, up-to-date Nvidia 340.x
drivers, Lustre client and BeeGFS client.
Making your compute nodes switch to CentOS 8 on an existing Qlustar
cluster installation is extremely simple: First create a CentOS 8 chroot
[1] optionally adding OpenHPC base support, then generate a CentOS 8 OS
image [2] selecting the modules you require and finally a boot config
[3] using the just generated image. After assigning [4] this boot config
to the nodes you want to run it on, you just need to reboot them and
voilà your CentOS 8 nodes are ready to be used.
Note that OpenHPC 1.3.9 was originally built for CentOS 7.7. We had to
make a few adjustments to make the OpenHPC parts relevant to Qlustar
(compilers, MPIs, library packages and applications) work for
CentOS 8. The OpenHPC test-suite was run successfully against these
components. Once OpenHPC 2.0 will be out, we'll publish instructions to
update to it. This will be straightforward.
Additional improvements with this release: Updates to the latest Lustre
2.12.4 LTS release and the newest Nvidia graphics drivers 340.64 adding
support for the latest Nvidia GPUs. These two updates apply to all
Qlustar 11.0 platforms (Ubuntu 18.04 and CentOS 7/8).
