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.
