In Situ Analysis and Visualization with SENSEI and Ascent
TimeSunday, 14 November 20218am - 12pm CST
DescriptionA key trend facing extreme-scale computational science is the widening gap between computational and I/O rates. A remedy known as in situ processing targets performing as much processing with the data while data is still resident in memory, thereby avoiding costly I/O. Current efforts in the HPC community produce several production tools for in situ processing with emphasis on scientific use cases on current and future 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 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 analyze, visualize or process data on HPC platforms while it is still resident in memory.
