Integrating SDN-Enhanced MPI with Job Scheduler to Support Shared Clusters
SDN-enhanced MPI is a framework that integrates the network programmability of Software-Defined Networking (SDN) with Message Passing Interface (MPI). The aim of SDN-enhanced MPI is to improve MPI communication performance by dynamically steering the traf

Preface
Sustained simulation performance is becoming an ever more important issue in High Performance Computing (HPC). Hardware is moving towards the Exaflop, and we will see such systems in the near future in China, Europe, Japan, and the USA. However, sustained performance is lagging behind substantially. Experts are worried that the level of sustained performance will stay as low as 1% of peak performance for typical applications. The workshop series on sustained simulation performance has set out 15 years ago to tackle this problem. The papers presented here a
