An object-oriented time warp simulation kernel

Abstract

The design of a Time Warp simulation kernel is made difficult by the inherent complexity of the paradigm. Hence it becomes critical that the design of such complex simulation kernels follow esta- blished design principles such as object-oriented design so that the im- plementation is simple to modify and extend. In this paper, we present a compendium of our efforts in the design and development of an object- oriented Time Warp simulation kernel, called warped. warped is a pu- blically available Time Warp simulation kernel for experimentation and application development. The kernel defines a standard interface to the application developer and is designed to provide a highly configurable en-vironment 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 worksta- tions, a SUN SMP workstation, the IBM SP1/SP2 multiprocessors, the Cray T3E, the Intel Paragon, and IBM-compatible PCs running Linux.
