Title
A new fast algorithm for connecting the INET simulation framework to applications in real-time
Abstract
The coupling of real implementations with simulations helps the developer to better understand the behavior of the real system by shifting to the simulation the parts of the overall system that he cannot influence. This was done for MPI programs in MPI-NeTSim. where the network and transport protocol are simulated in OMNeT++ but the original MPI code executes unchanged. We previously developed a static time factoring algorithm to accurately handle the discrepancies between the wall clock time of the application and the virtual simulation time. However, the original algorithm proved to be too slow for simulations with a higher number of hosts and a greater amount of data. In this paper, we introduce a faster adaptive algorithm that no longer uses time factors nor requires a full system-wide synchronization but still meets the conditions of the ordering of events in a distributed system. The new algorithm scales to significantly more hosts and data.
