Greg Becker scales projects and mountains
Computer scientist Greg Becker contributes to HPC research and development projects for LLNL’s Livermore Computing division.
Parallel Software Development Tools
We’re working on a new generation of tools to help our users with exascale machine bottlenecks. Our research emphasizes performance analysis and code correctness and aims to address these main challenges: seamless integration with programming models, scalability, automatic analysis, detection of inefficient resource usage, and tool modularity.

Ambassadors of Code
LLNL’s culture of open-source software development strengthens Laboratory programs with an engaged user community.
Behind the Scenes of a Hackathon
Computing’s hackathons provide 24-hour opportunities to brainstorm, foster creativity, prototype, and explore.
Sphinx: Integrated Parallel Microbenchmark Suite
Sphinx, an integrated parallel microbenchmark suite, consists of a harness for running performance tests and extensive tests of MPI, Pthreads and OpenMP. LLNL adaptations include extensive tests of the Pthreads interface and integration of the LLNL OpenMP Performance Suite. Sphinx is highly portable, and the test harness provides a flexible mechanism for running performance tests. The entire suite is implemented in C and has been run on a wide variety of platforms.
Spack: A Flexible Package Manager for HPC Software
Livermore builds an open-source community around its award-winning HPC package manager.
Greg Lee appreciates a challenge, both on and off the court
Greg Lee helps develop tools designed to boost performance and productivity of Livermore scientists.
ShipIt Day
Computing’s popular ShipIt Day events (also known as hackathons) are held several times a year.
Todd Gamblin goes to extremes
Todd Gamblin leads the PAVE project, which develops performance data visualization techniques that are more intuitive for application scientists.
We develop inventive software to enable innovative solutions
Software is everywhere at LLNL. As a Department of Energy (DOE) lab, we strengthen national and global security with a range of programs in fields like counterterrorism, biosecurity, and energy. Our work also contributes to the National Nuclear Security Administration’s stockpile stewardship mission. Researchers inside and outside the Lab rely on our high performance computing (HPC) center to advance science and technology.
