In 2010, when we embarked upon our mission to port Slurm to our Cray XT and XE systems, we discovered first-hand the high quality software engineering that has gone into the creation of this product. From its very core Slurm has been designed to be extensible and flexible. Moreover, as our work progressed, we discovered the high level of technical expertise possessed by SchedMD who was very quick to respond to our questions with insightful advice, suggestions and clarifications. In the end we arrived at a solution that more than satisfied our needs. The project was so successful we have now migrated all our production science systems to Slurm, including our 20 cabinet Cray XT5 system. The ease with which we have made this transition is testament to the robustness and high quality of the product but also to the no-fuss installation and configuration procedure and the high quality documentation. We have no qualms about recommending Slurm to any facility, large or small, who wish to make the break from the various commercial options available today.
