The growth in the number of computational resources used by high-performance computing
(HPC) systems leads to an increase in failure rates. Fault-tolerant techniques will become …

This work is based on the seminar titled 'Resiliency in Numerical Algorithm Design for
Extreme Scale Simulations' held March 1–6, 2020, at Schloss Dagstuhl, that was attended …

Dynamic Processes support was added to MPI in version 2.0 of the standard. This feature of
MPI has not been widely used by application developers in part due to the performance cost …

Progress in numerical weather and climate prediction accuracy greatly depends on the
growth of the available computing power. As the number of cores in top computing facilities …

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

Scientists from many different fields have been developing Bulk‐Synchronous MPI
applications to simulate and study a wide variety of scientific phenomena. Since failure rates …

Fault tolerance for the upcoming exascale generation has long been an area of active
research. One of the components of a fault tolerance strategy is checkpointing. Petascale …

When an MPI program experiences a failure, the most common recovery approach is to
restart all processes from a previous checkpoint and to re-queue the entire job. A …

Many geophysical imaging applications, such as full-waveform inversion, often rely on high-
performance computing to meet their demanding computational requirements. The failure of …

The recently proposed MPI Sessions extensions to the MPI standard present a new
paradigm for applications to use with MPI. MPI Sessions has the potential to address several …
