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 …

Next-generation systems face a wide range of new potential sources of application
interference, including resilience actions, system software adaptation, and in situ analytics …

The increase in scale and heterogeneity of high-performance computing (HPC) systems
predispose the performance of Message Passing Interface (MPI) collective communications …

In order to bridge the gap between the applications' I/O needs on future exascale platforms,
and thecapabilities of conventional memory and storage technologies, HPC system designs …

Fault-tolerance poses a major challenge for future large-scale systems. Active research into
coordinated, uncoordinated, and hybrid check pointing systems has explored how the …

With the increased scale expected on future leadership-class systems, detailed information
about the resource usage and performance of MPI message matching provides important …

The shift towards high-bandwidth networks driven by AI workloads in data centers and HPC
clusters has unintentionally aggravated network latency, adversely affecting the …

Relaxed synchronization offers the potential of maintaining application scalability by
allowing many processes to make independent progress when some processes suffer …

Exascale systems will suffer failures hourly. HPC programmers rely mostly on application-
level checkpoint and a global rollback to recover. In recent years, techniques reducing the …

Next-generation HPC computing platforms are likely to be characterized by significant,
unpredictable nonuniformities in execution time among compute nodes and cores. The …
