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.

As a result of the well designed installation and great support from Q-Leap, we are able to operate our HPC Cluster at minimal cost and extremely high availability. It runs flawlessly on our heterogenous hardware setup and provides maximum compute throughput. Q-Leap reacts quickly to support requests and delivers smart solutions to tricky problems.

Our institute focusses its research in the structural and functional organisation of the human brain. Therefore, we depend very much on reliable and performant HPC resources. Qlustar provides just the right platform for this. We rely on Qlustar clusters for more than a decade now and continue to be very satisfied.
Wolfgang Rieger
Inst. of Neuroscience and Medicine
Forschungszentrum Jülich, Germany
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.
