MFEM is an open-source, lightweight, flexible and scalable C++ library for modular finite
element methods that features arbitrary high-order finite element meshes and spaces …

The term “in situ processing” has evolved over the last decade to mean both a specific
strategy for visualizing and analyzing data and an umbrella term for a processing paradigm …

This paper aims to create a transition path from file-based IO to streaming-based workflows
for scientific applications in an HPC environment. By using the openPMP-api, traditional …

Inline and in transit visualization are popular in situ visualization models for high
performance computing (HPC) applications. Inline visualization is invoked through a library …

Although supercomputers are becoming increasingly powerful, their components have thus
far not scaled proportionately. Compute power is growing enormously and is enabling finely …

Triggers are an important mechanism for adapting visualization, analysis, and storage
actions. With this work, we describe the Ascent in situ infrastructure's system for triggers. This …

This chapter describes Ascent, a production library for in situ visualization and analysis on
exascale architectures. It begins by describing the library's focal points: minimizing …

This work compares the two major paradigms for doing in situ visualization: in-line, where
the simulation and visualization share the same resources, and in-transit, where simulation …

LLNL is developing next-generation multi-physics simulation capabilities for national
security applications under the Multiphysics on Advanced Platforms Project (MAPP). MAPP …

Data representation and coupling between scientific libraries is a key challenge to building a
vibrant ecosystem of HPC simulation tools. From bespoke data structures to hundreds of file …
