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.
VCK
Vlasov Continuum Kinetics
A high-fidelity, specialized code solves partial differential equations for plasma simulations.
OpenZFS
Improving File System Efficiency
LC’s adaptation of OpenZFS software provides high performance parallel file systems with better performance and scalability.
libROM
POD-Based Reduced Order Modeling
libROM is a library designed to facilitate Proper Orthogonal Decomposition (POD) based Reduced Order Modeling (ROM).
GOLLNLP
Improving Efficiency and Robustness of the U.S. Electrical Power Grid using HPC
Responding to a DOE grid optimization challenge, an LLNL-led team developed the mathematical, computational, and software components needed to solve problems of the real-world power grid.
Spack
A Flexible Package Manager for HPC Software
Livermore builds an open-source community around its award-winning HPC package manager.
Variorum
Vendor-Agnostic Power Management
Collecting variants in low-level hardware features across multiple GPU and CPU architectures.
zfp
Compressed Floating-Point and Integer Arrays
zfp is an open-source C/C++ library for compressed floating-point and integer arrays that support high throughput read and write random access.
Quandary
Scalable Quantum Optimal Control
Quandary is an open-source C++ package for optimal control of quantum systems on classical high performance computing platforms.
MFEM
Scalable Finite Element Discretization Library
The open-source MFEM library enables application scientists to quickly prototype parallel physics application codes based on PDEs discretized with high-order finite elements.
Merlin
Machine Learning for HPC Workflows
Merlin is an open-source workflow orchestration and coordination tool that makes it easy to build, run, and process large-scale workflows.
ETHOS
Enabling Technologies for High-Order Simulations
The Enabling Technologies for High-Order Simulations (ETHOS) project performs research of fundamental mathematical technologies for next-generation high-order simulations algorithms.
UMap
An Application-Oriented, User-Level Memory-Mapping Library
UMap uniquely exploits the prominent role of complex memories in today’s servers and offers new capabilities to directly access large memory-mapped datasets.
Legacy
PERM
A 'C' library for persistent heap management
PERM is a 'C' library for persistent heap management and is intended for use with a dynamic-memory allocator (e.g. malloc, free).
