Middleware in Modern High Performance Computing System Architectures

Overview A recent trend in modern High Performance Computing (HPC) system architectures employs "Lean" compute nodes running a lightweight Operating System (OS). Certain parts of the OS as well as other system software services are moved to service nodes in order to increase performance and scalability. This paper examines the impact of this HPC system architecture trend on HPC "Middleware" software solutions, which traditionally equip HPC systems with advanced features, such as parallel and distributed programming models, appropriate system resource management mechanisms, remote application steering and user interaction techniques.
