The Qlustar team is pleased to announce the immediate availability of
Qlustar 10.1 for download at https://qlustar.com/download.
Adding support for CentOS 7.5 [https://www.centos.org/] as a new fully
supported edge platform, combined with the integration of OpenHPC
[https://openhpc.community], this release marks an important milestone
in Qlustar's history. Qlustar users now have the option to run the most
popular HPC platform with the same ease-of-use they're familiar with
from our Debian/Ubuntu based platform.
The second big new feature of 10.1 is a totally revamped boot
process of Qlustar nodes: QluMan 10.1 now supports downloading the OS
image via a fast and fault-tolerant multi-cast mechanism. This can
reduce boot-time dramatically and allows for simultaneous and reliable
booting of a virtually unlimited number of cluster nodes without
increasing overall boot-time.
On top of that, Qlustar OS images are now created using squashfs with
compression. This reduces the memory footprint of the OS by roughly 66%
so that a standard compute node image with slurm and IB support consumes
a mere 160MB of RAM.
Qlustar 10.1 is a feature release with its core still based on
Ubuntu/Xenial (16.04). Highlights among the various <strong>major
component updates</strong> include Kernel 4.14.x, Slurm 220.127.116.11, CUDA
9.1 and Lustre 2.11. Please read the release notes at
for more details.
