An Object-Oriented Time Warp Simulation Kernel

The design of a Time Warp simulation kernel is made dif-cult by the inherent complexity of the paradigm. Hence it becomes critical that the design of such complex simulation kernels follow established design principles such as object-oriented design so that the implementation is simple to modify and extend. In this paper, we present a compendium of our eeorts in the design and development of an object-oriented Time Warp simulation kernel, called warped. warped is a pub-lically available Time Warp simulation kernel for experimentation and application development. The kernel deenes a standard interface to the application developer and is designed to provide a highly conngurable environment for the integration of Time Warp optimizations. It is written in C++, uses the MPI message passing standard for communication, and executes on a variety of platforms including a network of SUN workstations , a SUN SMP workstation, the IBM SP1/SP2 multiprocessors, the Cray T3E, the Intel Paragon, and IBM compatible PCs running Linux.
