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(More)
Synchronizing parallel discrete event simulation (PDES) involves signiicant overheads. These overheads form a sizeable part of the simulation time resulting in marginal performances of parallel discrete event simulators. While considerable investigations have been conducted to analyze and optimize each of these synchronization strategies, little attention(More)
Recent breakthroughs in communication and software engineering has resulted in significant growth of web-based computing. Web-based techniques have been employed for modeling, simulation, and analysis of systems. The models for simulation are usually developed using component based techniques. In a component based model, a system is represented as a set of(More)
Multi-resolution models can be statically (i.e., before simulation) or dynamically (i.e., during simulation) abstracted to accelerate the simulations without compromising the analysis goals. However, abstractions must be carefully chosen because not all abstractions improve performance. Unfortunately, identifying performance enhancing transformations,(More)
Web-based simulations are performed by utilizing the resources of the Word Wide Web (WWW) such as proprietary components/models developed by third party mod-elers/manufacturers and web-based computational infras-tructures (or compute servers). Access to such web-based resources, third party resources in particular, is usually cir-cumscribed by a variety of(More)
