An Introduction to Jetstream

Presenter(s): Virginia Trueheart (TACC)

Presentation Slides

Jetstream is an interactive computing resource designed to make High Performance Computing accessible to users that are not part of traditional HPC fields. This tutorial aims to introduce Jetstream's capabilities to this expanded user base. It will demonstrate how to access the system, make use of the various Virtual Machines available, and use publicly available images to assist with research. It will also cover how to create, modify, and save personal images that can be customized to individual workflows and be saved long term for reference in publication.

XSEDE ECSS project: High Performance Computing Resources in Support of Spatiotemporal Relational Data Mining for Anticipation of Severe Weather.
Amy McGovern and her collaborator Corey Potvin from the National Severe Storms Laboratory are developing and applying novel spatiotemporal data mining techniques to supercell thunderstorm simulations, with the goal of identifying tornado precursors. The overall goal of the project is to improve tornado warning lead time and accuracy by integrating into the "Warn on Forecast" project, a National Oceanic and Atmospheric Administration research program tasked to increase tornado, severe thunderstorm, and flash flood warning lead times.
XSEDE ECSS staff was enlisted to see what could be found using 3D visualization techniques and an interactive user interface. The resulting images and animations will assist in defining storm features and as input to the data mining: ensuring automatically extracted objects match visually identified ones. This talk will feature graphics from a selection of three (5.7 TB) datasets, with visualization samples identifying various supercell thunderstorm features.
