In this talk I will present an overview of the features of the OpenHPC stack, whose first version was released last year. I will also review our experience using it since then, and how we decided to migrate our whole HPC cluster (made of 100 nodes, Infiniband hetereogeneous network and LUSTRE filesystem) to openHPC, highlighting the advantages of this openHPC stack for small-medium-size HPC systems of the like. I will review some highlights of the installation process and a small demo will be presented. Some very few cons will also be exposed, in the sake of fairness.
