The higher-level interface presented to the user by such a language also allows optimizations to be performed that are difficult and cumbersome with current parallel simulators, such as granularity control. APOSTLE is a new high-level simulation-oriented language for PDES, and in this paper we report that the APOSTLE granularity control mechanism reduced simulation run-times by as much as 80%. We also report that APOSTLE achieved a parallel speed-up of around 9 on 16 processors relative to its optimized sequential implementation and a parallel speed-up of around 6 on 16 processors relative to MODSIM II. Overall, we believe that the widespread success of PDES can only be achieved using a simulation-oriented language, and that APOSTLE has made a significant contribution towards this goal. DOI
