Timothy and Andrew attended a site administrators course in Potch over the last 3 days. The focus was on doing higher level site admin training and to thrash out some problems we've been experiencing on SAGrid. The closing session included some very interesting talks by NWU staff on the use of their local HPC cluster in chemical engineering and aerodynamic design for high performance gliders. We'd also like to extend our thanks to Hannes, Zuko and Attie for their kind hospitality.
