ABSTRACT
A technique called updateable simulations is proposed to reduce the time to complete multiple executions of a discrete event simulation program. This technique updates the results of a prior simulation run rather than re-execute the entire simulation to take into account variations in the underlying simulation model. A framework for creating updateable simulations is presented. This framework is applied to the problem of simulating a set of cascaded ATM multiplexers and a network of ATM switches. Performance measurements of sequential and parallel implementations of these simulations on a shared memory multiprocessor are presented, demonstrating that updateable simulations can yield substantial reductions in the time required to complete multiple simulation runs if there is much similarity among the runs.
