A Middleware Level Active Replication Manager for High Performance HLA-based Simulations on SMP Systems

In this paper we explore active replication in the context of advanced simulation systems, with the aim of improving the timeliness for the production of simulation output. Our proposal is framed by the high-level-architecture (HLA), i.e. the middleware based standard for interoperability of simulation packages. It results in the design and implementation of an active replication management layer (ARML) targeted to SMP computing systems, which supports the execution of (diversity-based) active replicas of a same simulation package in a totally transparent manner
