A prototype concurrent simulation toolkit

The EcliPSe system is a prototype toolkit for concurrent stochastic simulation. The toolkit provides high-level simulation-oriented primitives which an application programmer uses to describe the simulation process using a sequential computation model. The system transparently replicates appropriate sections of the simulation when the program is executed on a concurrent system. By binding to machine-dependent versions of the EcliPSe library, the simulation program can execute without modification on a variety of architectures, including uniprocessors, hypercubes, shared-memory machines, and loosely coupled networks, leading, in those experiments conducted, to near-linear speedup. The main design aspects of the EcliPSe system, salient implementation features, and performance figures for some simulation applications are presented.<
