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 17.11.9.2, CUDA 9.1 and Lustre 2.11.
