The share of the top 500 supercomputers with NVIDIA GPUs is now over 25% and continues
to grow. While fault tolerance is a critical issue for supercomputing, there does not currently …

Scaling supercomputers comes with an increase in failure rates due to the increasing
number of hardware components. In standard practice, applications are made resilient …

Transparently checkpointing MPI for fault tolerance and load balancing is a long-standing
problem in HPC. The problem has been complicated by the need to provide checkpoint …

Efficient utilization of today's high-performance computing (HPC) systems with complex
software and hardware components requires that the HPC applications are designed to …

With the scaling up of high-performance computing systems in recent years, their reliability
has been descending continuously. Therefore, system resilience has been regarded as one …

We propose LightPC, a lightweight persistence-centric platform to make the system robust
against power loss. LightPC consists of hardware and software subsystems, each being …

We investigate the sources of detected unrecoverable errors (DUEs) in graphics processing
units (GPUs) exposed to a neutron beam. Illegal memory accesses and interface errors are …

While many HPC applications are known to have long runtimes, this is not always because
of single large runs: in many cases, this is due to ensembles composed of many short runs …

This article studies checkpointing strategies for parallel applications subject to failures. The
optimal strategy to minimize total execution time, or makespan, is well known when failure …

Until now, jobs running on HPC clusters were tied to the node where their execution started.
We have removed that limitation by integrating a user-level checkpoint/restart library into a …
