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 …

The next generation of supercomputers will break the exascale barrier. Soon we will have
systems capable of at least one quintillion (billion billion) floating-point operations per …

An apparatus includes processor component caused to: retrieve metadata of organization of
data within a data set, and map data of organization of data blocks within a data file; receive …

Today, soft errors are one of the major design technology challenges at and beyond the
22nm technology nodes. This article introduces the soft error problem from the perspective …

With the aim of imaging subsurface discontinuities, seismic data recorded at the surface of
the Earth must be numerically re-positioned at locations in the subsurface where reflections …

With the rapid scale out of supercomputers comes a corresponding higher failure frequency.
Fault-tolerant methods have evolved to adapt to high rates of failure, but the behavior of MPI …

Ultra-large–scale simulations via solving partial differential equations (PDEs) require very
large computational systems for their timely solution. Studies shown the rate of failure grows …

Current HPC environments require parallel programs that are both malleable and fault-
tolerant. Malleability denotes the ability to embrace system-initiated resource changes, and …

Upcoming HPC clusters will feature hybrid memories and storage devices per compute
node. In this work, we propose to use the MPI one-sided communication model and MPI …

Fault resilience has became a major issue for HPC systems, in particular in the perspective
of future E-scale systems, which will consist of millions of CPU cores and other components …
