[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.

[Qlustar-Announce] CentOS 8 support has arrived
by General announcements about Qlustar 17 Apr '20

17 Apr '20

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).

[Qlustar-Announce] Qlustar Feature Update 02/20
by General announcements about Qlustar 13 Feb '20

13 Feb '20

A number of new Qlustar features were completed recently and published together with the latest security updates ([1], [2]). QluMan 11.0.3.1 has the following new capabilities: * The 'Write Files' dialog [3] got a complete revamp: + The configuration files/links belonging to different QluMan 'Config Classes' are now neatly arranged in a single collapsible tree-view. + Colored LEDs have been introduced to indicate whether pending changes of the config files are waiting to be written and which files are affected. + It is now straightforward to cycle through the list of changed files exclusively, allowing for a fast overview of pending changes in diff format. + Selecting individual Config Classes to be written has become a lot simpler by providing checkboxes in the tree-view. + Overall, the new dialog greatly enhances the clarity of the cluster configuration space. It provides way better control and confidence when performing configuration changes. * Messages for config file writing have been added to the QluMan Log Viewer [4]. * The so-called QluMan 'save-button interface' was improved and implemented for the editing of command names in the Command Editor. Now name labels turn green when changed and black after being saved, improving transparency. If you use QluMan singularity images, make sure you download [5] the latest version.
