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.
