Why use Qlustar?

Dive in deeper and discover the numerous reasons why you may want to join our ever growing user community and also deploy Qlustar on your systems. Here are a few of them:

Minimal Cluster Node OS

Powerful and manageable clusters need a consistent and light-weight node OS. Qlustar's image modules allow you to generate your custom tailored OS images reproducibly and with astonishing ease.

QluMan - The Control Center

Cluster configuration, management and operation is easily performed via the powerful yet simple to use QluMan GUI. It communicates with the QluMan server components on the head-node(s).

Flexible and configurable

No two clusters are alike. Qlustar allows you to customize most aspects of your installation. It helps you to achieve your design goals efficiently and reliably resulting in a stable and performant system.

Spack integration

Get access to thousands of HPC packages, MPI variants, compilers, applications and libraries via the seamless integration of the Spack package manager. All optimized to your hardware platform.

100% Open Source and free to use

A production cluster could cost you a fortune in license fees. With Qlustar you can run your system at no cost and at the same time unchain yourself from proprietary software. If you have too little resources to manage your cluster on your own, professional support is available to help you out.

We have a Q-Leap supported Lustre system in production since more than 5 years. It serves user data for many large Compute Clusters. During this time, Q-Leap provided very good support and was able to deliver great solutions to complex problems many times.

We have been running a Qlustar cluster for parallel 3D image processing since 2006. We would absolutely recommend Qlustar to others looking for a reliable and performant Cluster Operating System! The fact that it is completely Linux based not only makes it easy to use, it is also very flexible and future-proof.
