Extreme Scale Simulations' held March 1–6, 2020, at Schloss Dagstuhl, that was attended …

With the advent of exascale computing, issues such as application irregularity and
permanent hardware failure are growing in importance. Irregularity is often addressed by …

Recent Exascale supercomputers consist of millions of processing units, and this number is
still growing. Therefore, hardware failures, such as permanent node failures, become …

While checkpointing is typically combined with a restart of the whole application, localized
recovery permits all but the affected processes to continue. In task-based cluster …

Exascale supercomputers consist of millions of processing units, and this number is still
growing. Therefore, hardware failures, such as permanent node failures, become …

Integrating recent advancements in resilient algorithms and techniques into existing codes is
a singular challenge in fault tolerance-in part due to the underlying complexity of …

Exceptions and errors occurring within mission critical applications due to hardware failures
have a high cost. With the emerging Next Generation Platforms (NGPs), the rate of hardware …

Benefits of local recovery (restarting only a failed process or task) have been previously
demonstrated in parallel solvers. Local recovery has a reduced impact on application …

Abstract High-Performance Computing (HPC) enables solving complex problems from
various scientific fields including key societal problems such as COVID-19. Recently …
