News Item

Specialized hardware modules and software libraries to optimize memory access while simultaneously increasing memory capacity for data-intensive applications.

Project

An optics element team and two open-source software teams (UMap and UnifyFS) are LLNL's winners of this year's awards.

News Item

The open-source MFEM library enables application scientists to quickly prototype parallel physics application codes based on PDEs discretized with high-order finite elements.

Project

Two LLNL teams have come up with ingenious solutions to a few of the more vexing difficulties. For their efforts, they’ve won awards coveted by scientists in the technology fields.

News Item

Bugs, broken codes, or system failures require added time for troubleshooting and increase the risk of data loss. LLNL has addressed failure recovery by developing the Scalable Checkpoint/Restart (SCR) framework.

News Item

With SCR, jobs run more efficiently, recover more work upon failure, and reduce load on critical shared resources.

Project

zfp is an open-source C/C++ library for compressed floating-point and integer arrays that support high throughput read and write random access.

Project

Collecting variants in low-level hardware features across multiple GPU and CPU architectures.

Project

LLNL’s HPC capabilities play a significant role in international science research and innovation, and Lab researchers have won 10 R&D 100 Awards in the Software–Services category in the past decade.

News Item

Release the codes! With a dynamic developer community and a long history of encouraging open-source software, LLNL has reached quadruple-digit GitHub offerings.

News Item

News Item

UMap uniquely exploits the prominent role of complex memories in today’s servers and offers new capabilities to directly access large memory-mapped datasets.

Project

This open-source file system framework accelerates hierarchical HPC I/O operations with effective, efficient use of node-local storage.

Project

Discover how the software architecture and storage systems that will drive El Capitan’s performance will help LLNL and the NNSA Tri-Labs push the boundaries of computational science.

News Item

Backed by Spack’s robust functionality, the Packaging Working Group manages the relationships between user software and system software.

News Item

PERM is a 'C' library for persistent heap management and is intended for use with a dynamic-memory allocator (e.g. malloc, free).

Project

Leading HPC publication HPCwire presented Spack developers with the Editor's Choice Award for Best HPC Programming Tool or Technology at SC23.

News Item
