The Qlustar releases 11.0.0.1-b514f1258 and 10.1.1.5-b509f1256 are ready including a number of security and bug fixes as well as a couple of enhancements. Please check the following web pages for details about security fixes: https://qlustar.com/news/qsa-0624191-linux-kernel-vulnerabilities https://qlustar.com/news/qsa-0624192-security-update-bundle The following non-security related enhancements/bug fixes are included: * Fix permissions of certain image base directories. Before that it would have been possible for any user to fill a couple of tmpfs filesystems thus blocking some main memory resources of compute nodes. * The nvidia image module is now based on driver version 430.26 supporting the newest GPUs (Qlustar 11.0 only). * QluMan fixes: - Fix rights management for QluMan users - Prevent the main head-node from being deleted (Qlustar 11.0 only). - Fix exceptions of the slurm job window that occurred in certain situations.

[Qlustar-Announce] Qlustar 11 released
by General announcements about Qlustar 14 Jun '19

14 Jun '19

The Qlustar team is pleased to announce the immediate availability of Qlustar 11.0 for download at https://qlustar.com/download. It updates Qlustar's core platform to current Ubuntu 18.04 LTS. The CentOS [https://www.centos.org/] edge platform is now based on 7.6 with full integration of the just released OpenHPC 1.3.8 [https://openhpc.community/]. As a result of our continuous platform optimization/simplification process we moved to dnsmasq [http://dnsmasq.org/] as a replacement of the previously used ISC DHCP and atftp TFTP server. dnsmasq also provides cluster internal name services (DNS) replacing the NIS hosts map and acts as a DNS proxy. In addition to the dnsmasq management interface, the second major feature of QluMan is the possibility to handle Network Filesystem resources. Initially this supports NFS mounts including RDMA connections and a mechanism to automatically choose the optimal network path to the NFS server. Mount resources are implemented as systemd automount units. This new interface replaces the previously used automount daemon which is now deactivated per default. Highlights among the various major component updates include Kernel 4.19.x, Slurm 18.08.x, CUDA 10.1, OpenMPI 4.0.1 and BeeGFS 7.1.3. Please read the release notes for more details [https://docs.qlustar.com/en-US/Qlustar_Cluster_OS/11.0/html-single/Release_…].

We are organizing a Birds of a feather session [1] at this years ISC (Wednesday, June 19th 2:45pm - 3:45pm, Room Kontrast). There will be two presentations one by Qlustar founder Roland Fehrenbacher and a second one by Ansgar Esztermann from the Max-Planck Institute in Göttingen. The goal of the BoF is to bring together developers, HPC cluster admins and hardware vendors to identify the most pressing issues to further enhance Qlustar's suitability as an open-source full stack HPC management solution. So if you're in Frankfurt next week, take the chance to join us. [1] https://2019.isc-program.com/?post_type=page&p=11&id=bof125&sess=sess237
