Software Rejuvenation Schemes for Time Warp-Based PDES

Software rejuvenation is a technique to prevent the aging of running software. Recently, benefits of software rejuvenation in high-performance computing (HPC) areas have received attention. In time warp-based parallel discrete event simulation (PDES) systems, it is important to improve performance to equalize simulation progress in processes. In this article, we consider a number of schemes for time warp-based PDES to avoid the imbalance simulation progress introduced by rejuvenation.
