“…This is the case of struct MsgS* and char* parameters, which represent pointers to memory areas that contain data to be accessed by both B-RTI and the federate. For instance, when the ReflectAttributeValues() callback is issued, the struct MsgS* parameter b An early implementation [22] relying on a socket based approach to support the interaction between the replication management modules, has shown that the kernel mode overhead can be affordable only for coarse grain applications.…”

Active replication has been widely explored to achieve fault tolerance and to improve system availability, especially in service oriented applications. In this paper we explore software diversity-based active replication in the context of advanced simulation systems, with the aim at improving the timeliness for the production of simulation output. Our proposal is framed by the High-Level-Architecture (HLA), namely a middleware based standard for simulation package interoperability, and results in the design and implementation of an Active Replication Management Layer (ARML) targeted to off-the-shelf SMP computing systems. This layer can be interposed in between each simulator instance and the underlying HLA middleware component, in order to support the execution of diversity-based active replicas of a same simulation package in a totally transparent manner. Beyond presenting the replication framework and the design/implementation of ARML, we also report the results of an experimental evaluation on a case study, quantifying the benefits from our proposal in terms of both simulation execution speed and performance guarantees vs tunable software parameters.

“…Another federate replication structure has been proposed by Quaglia [93,94,95] In this thesis, we shall classify the federate replication structure proposed in [93,94,95] as No-Barrier federate replication structure. In such a structure, replicas of a federate connects to the same DRC through a replication module (e.g., ARML) and they are required to be Piecewise Equivalent.…”
