The widening gap between computational and I/O rates is a key challenge for many computational science efforts. In situ processing, where visualization and analysis process data while it is being generated, is an important solution for this challenge.
The HPC visualization community provides several production tools for in situ processing and is actively researching infrastructures and approaches to help with in situ use cases on HPC platforms. This tutorial blends lectures and hands-on examples to introduce attendees to in situ processing concepts and provide practical experience using state-of-the-art and -practice in situ tools, including SENSEI, Ascent, ParaView Catalyst, VisIt Libsim, Cinema and ADIOS.
Attendees will learn how to use the SENSEI and Ascent in situ interfaces to couple simulation codes to multiple endpoints. This tutorial is ideal for those who would like to learn how to use in situ processing to analyze, visualize, or process data on HPC platforms.
