Qlustar Feature Update 01/22
by General announcements about Qlustar 10 Jan '22

10 Jan '22

A number of new Qlustar features were completed recently and published together with the latest security updates. QluMan 12.0.6.0 has the following new capabilities: - QLUMAN TIMERS [1] present a new Config class assignable to nodes. They allow for time-based execution of commands on nodes and are easily configured via the GUI. - ENHANCEMENTS OF THE SLURM GUI COMPONENT [2]: * Added on-the-fly job filtering and job grouping. * Significantly improved mechanism to transfer job data. The QluMan GUI is now able to smoothly handle thousands of jobs. - HARDWARE DETECTION INFO for nodes in the GUI Enclosure view [3] now transparently highlights misconfigurations, helping admins to track down faulty settings. - FILTERS IN USER/GROUP MANAGEMENT [4] have been added, making LDAP management a lot clearer and easier to follow. Other new features: - MELLANOX OFED [5] drivers and tools have been included for optimized support of clusters with newest Infiniband (IB) technology. Qlustar now automatically detects whether IB adapters supported by the current Mellanox OFED release are present and activates its drivers if that's the case. For all other IB hardware, the in-kernel drivers are used. - GPU DIRECT RDMA [6] support has been added for nodes running Nvidia GPUs together with IB adapters supported by Mellanox OFED. It provides a significant decrease in GPU-GPU communication latency and completely offloads the CPU, removing it from all GPU-GPU communications across the network. - The VIRTUALGL image module is now production ready. When used in a node image, Qlustar can provide 3D remote visualization on nodes with the required hardware.

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.
