WARPED: a time warp simulation kernel for analysis and application development

Abstract

WARPED is a publically-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 environment for the integration of time warp optimizations. It is written in C++, uses the MPI (Message Passing Interface) standard and shared memory 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 Intel Paragon and IBM-compatible PCs running Linux. WARPED is distributed with several applications and includes a sequential kernel implementation for comparative analysis. The kernel supports LP (logical process) clustering, various time warp algorithms and several optimizations that dynamically adjust simulation parameters.
