Abstract
Federated simulation interfaces such as the High Level
Architecture (HLA) were designed for interoperability,
and as such are not traditionally associated with high performance
computing. In this paper, we present results
of a case study examining the use of federated simulations
using runtime infrastructure (RTI) software to realize
large-scale parallel network simulators. We examine the
performance of two different federated network
simulators, and describe RTI performance optimizations
that were used to achieve efficient execution. We show
that RTI-based parallel simulations can scale extremely
well and achieve very high speedup. Our experiments
yielded more than 80-fold scaled speedup in simulating
large TCP/IP networks, demonstrating performance of up
to 6 million simulated packet transmissions per second on
a Linux cluster. Networks containing up to two million
network nodes (routers and end systems) were simulated.
