Reproducibility Report for the Paper: “Hybrid Speculative Synchronisation for Parallel Discrete Event Simulation”

The examined paper presents a parallel discrete-event simulation (PDES) runtime which is able to combine two disparate synchronization algorithms: Window Racer (conservative) and Time Warp (optimistic). The authors have uploaded their artifact to Zenodo, ensuring a DOI and long-term retention of the artifact earning the Artifacts Available badge. The artifact allows for easy re-running of all experiments and generation of all resultant figures. The dependencies are well documented. The software in the artifact runs correctly and is relevant to the paper. This paper can thus recieve the Artifacts Evaluated–Functional badge. In addition, the experimental parameters are easily adjusted and reconfigured, thus earning the Artifacts Evaluated–Reusable badge. Although some of the reproduced graphs show different data, the conclusions and analysis of the original paper still hold and the Results Reproduced badge is awarded.
