Our research projects vary in size, scope, and duration, but they share a focus on developing tools and methods that help LLNL deliver on its missions to the nation and, more broadly, advance the state of the art in scientific HPC. Projects are organized here in three ways: Active projects are those currently funded and regularly updated. Legacy projects are no longer actively developed. The A-Z option sorts all projects alphabetically, both active and legacy.

Active | A-Z | Legacy

TESSA

Tracking Space Debris

Testbed Environment for Space Situational Awareness software helps to track satellites and space debris and prevent collisions.

Topological Analysis

Charting Data’s Peaks and Valleys

LLNL and University of Utah researchers have developed an advanced, intuitive method for analyzing and visualizing complex data sets.

TOSS

Speeding Up Commodity Cluster Computing

Researchers are developing a standardized and optimized operating system and software for deployment across Linux clusters to enable HPC at a reduced cost.
