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 re­execute 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
