Title:

Parallel Discrete Event Simulation on Metacomputing Systems

Abstract:
Recent advances in distributed computing such as volunteer and desktop grid
computing that aggregate loosely coupled resources have transformed the
execution of certain computational workloads that, in the past, were
reserved for processing on dedicated clusters.  Parallel discrete event
simulations have different requirements, such as time synchronization, than
programs that can exploit loosely coupled resources.  Consequently, these
codes are typically run on tightly coupled machines providing the best
opportunity for maximum speedup.  However, these facilities may not be
readily available to many users.

This talk explores the merging of these distinct computational domains
involving the execution of parallel discrete event simulation across loosely
coupled resources.  A master/worker architecture is proposed for parallel
discrete event simulation on metacomputing systems providing robust
executions under a dynamic set of services with system-level support for
fault tolerance, semi-automated client-directed load balancing, portability
across heterogeneous machines, and the ability to run codes on idle or
time-sharing clients without significant interaction by users.  Results indicate
that a master/worker approach utilizing loosely coupled resources is a viable
means for high throughput parallel discrete event simulation by enhancing
existing computational capacity or providing alternate execution capability
for less time-critical codes.
