SimCore: A Library for Rapid Development of Large Scale Parallel Simulations

Abstract

Abstract:We present the SimCore parallel simulation library, an object-oriented framework for developing parallel distributed discrete-event simulation applications, implemented in C++ with a Python front-end. SimCore is designed to scale to thousands of processors but is simple enough to use for application programmers, an outcome of its fast C++ core and message passing routines integrated with the full expressive power of Python. We discuss the design philosophy of SimCore including the software architecture and the C++/Python interface implementation that allows applications to be written in pure Python or a hybrid of Python and C++ or even pure C++. We also provide real world examples of the scalability and briefly describe a few diverse applications that have been deployed using SimCore.
