The Qlustar releases 18.104.22.168-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
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.
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
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
We are organizing a Birds of a feather session  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
