Scheduling algorithm for distributed simulation systems management

European Space Agency Simulation Language (ESL) is a simulation language used to simulate real life continuous control systems. With the emergence of the Internet as the mainstream technology, there is ample of motivation to develop a generic architecture which allows users to conduct simulations through the Internet. In this paper a three-tier system called Distributed Simulation Management Architecture (DSMA) is presented which manages ESL simulation processes in a heterogeneous High Performance Computer (HPC) network. Analysis has shown that it is possible to accurately predict the execution time of certain type of ESL programs. An Estimation Engine is presented in this paper which is capable of estimating the execution time of this type of ESL programs with up to 94% accuracy. A scheduling algorithm called Predictive Multi-Level Priority (PMLP) scheduling algorithm is also presented here. It can effectively reduce the latency of the scheduling process of DSMA.
