Experiences with the SEMPA Resource Manager for Real World Scientific

Abstract

The Sepma Resourse Manager is a resource management system for parallel applications in a network of workstations that enables the utilization of idle resources for parallel computing and shortens the execution time of parallel applications by dynamic load balancing at runtime. The network of workstations runs in a non-dedicated mode, where the Sepma Resourse Manager assigns hosts that are not required by interactive users to its batch jobs. The flexible structure of the Sepma Resourse Manager guarantees scalability and results in functions for transparent process migration and dynamic reconfiguration of the parallel execution environment. We present performance measurements with an industrial computational fluid dynamics program proving the efficiency of the Sepma Resourse Manager.
