Resilience is a major roadblock for HPC executions on future exascale systems. These
systems will typically gather millions of CPU cores running up to a billion threads …

We present here a report produced by a workshop on 'Addressing failures in exascale
computing'held in Park City, Utah, 4–11 August 2012. The charter of this workshop was to …

The limited scalability of current bus topologies for systems on chips (SoCs) dictates the
adoption of networks on chips (NoCs) as a scalable interconnection scheme. Current SoCs …

Reliability is a key challenge to be understood to turn the vision of exascale supercomputing
into reality. Inevitably, large-scale supercomputing systems, especially those at the …

Predicting which node will fail and how soon remains a challenge for HPC resilience, yet
may pave the way to exploiting proactive remedies before jobs fail. Not only for increasing …

Exascale computers will enable the unraveling of significant scientific mysteries. Predictions
are that 2019 will be the year of exascale, with millions of compute nodes and billions of …

Reliability is a serious concern for future extreme-scale high-performance computing (HPC)
systems. While the HPC community has developed various resilience solutions, the solution …

This paper presents a modular-redundant Message Passing Interface (MPI) solution, MR-
MPI, for transparently executing high-performance computing (HPC) applications in a …

We consider coordinating accesses to shared data structures in multiprocessor real-time
systems scheduled under preemptive global EDF. To our knowledge, prior work on global …

High performance computing will probably reach exascale in this decade. At this scale,
mean time between failures is expected to be a few hours. Existing fault tolerant protocols for …
