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.
Livermore builds an open-source community around its award-winning HPC package manager.
Sphinx, an integrated parallel microbenchmark suite, consists of a harness for running performance tests and extensive tests of MPI, Pthreads and OpenMP.
Spindle improves the library-loading performance of dynamically linked HPC applications. It plugs into the system’s dynamic linker and intercepts its file operations so that only one process (or…
StarSapphire is a collection of scientific data mining projects focusing on the analysis of data from scientific simulations, observations, and experiments.
LLNL’s Stack Trace Analysis Tool helps users quickly identify errors in code running on today’s largest machines.
SUNDIALS is a SUite of Nonlinear and DIfferential/ALgebraic equation Solvers for initial value problems for ordinary differential equation systems, sensitivity analysis capabilities, additive Runge-…
The Taurus Environmental Information Management System, or TEIMS, system manages collaborative tasks, site characterization, modeling, risk assessment, decision support, operations tracking,…
Testbed Environment for Space Situational Awareness software helps to track satellites and space debris and prevent collisions.
LLNL and University of Utah researchers have developed an advanced, intuitive method for analyzing and visualizing complex data sets.
Researchers have been developing a standardized and optimized operating system and software for deployment across a series of Linux clusters to enable high performance computing at a reduced cost…
Umpire is a resource management library that allows the discovery, provision, and management of memory on next-generation architectures.
This open-source file system framework supports hierarchical HPC storage systems by utilizing node-local burst buffers.
Veritas provides a method for validating proxy applications to ensure that they capture the intended characteristics of their parents.
Researchers develop innovative data representations and algorithms to provide faster, more efficient ways to preserve information encoded in data.
The scalable multigrid reduction in time (XBraid) approach constructs coarse time grids and uses each coarse time scale solution to improve the next finer-scale solution, ultimately yielding an…
