Department of Energy to Showcase World-Leading Science at SC19

The DOE’s national laboratories will be showcased at SC19 next week in Denver, CO. “Computational scientists from DOE laboratories have been involved in the conference since it began in 1988 and this year’s event is no different. Experts from the 17 national laboratories will be sharing a booth featuring speakers, presentations, demonstrations, discussions, and simulations. DOE booth #925 will also feature a display of high performance computing artifacts from past, present and future systems. Lab experts will also contribute to the SC19 conference program by leading tutorials, presenting technical papers, speaking at workshops, leading birds-of-a-feather discussions, and sharing ideas in panel discussions.”

Epic HPC Road Trip stops at NERSC for a look at Big Network and Storage Challenges

In this special guest feature, Dan Olds from OrionX continues his Epic HPC Road Trip series with a stop at NERSC. “NERSC is unusual in that they receive more data than they send out. Client agencies process their raw data on NERSC systems and then export the results to their own organizations. This puts a lot of pressure on storage and network I/O, making them top priority at NERSC.”

NERSC Unveils Mural for pending Perlmutter Supercomputer

NERSC has unveiled the mural that will grace the cabinets of the Perlmutter supercomputer that will be installed at Berkeley Lab in 2020. “The mural pays tribute to the system’s namesake, Nobel Laureate Saul Perlmutter. The Berkeley Lab physicist led the team whose work at NERSC contributed to the Nobel prize-winning insight that the universe’s expansion is speeding up. The resulting efforts to explain this acceleration led to today’s model of a universe dominated by dark energy and dark matter.”

Supercomputing and the Scientist: How HPC and Analytics are transforming experimental science

In this video from DataTech19, Debbie Bard from NERSC presents: Supercomputing and the scientist: How HPC and large-scale data analytics are transforming experimental science. “Debbie Bard leads the Data Science Engagement Group NERSC. NERSC is the mission supercomputing center for the USA Department of Energy, and supports over 7000 scientists and 700 projects with supercomputing needs.”

Supercomputing Post-Wildfire Water Availability

A new study by scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) uses a numerical model of an important watershed in California to shed light on how wildfires can affect large-scale hydrological processes, such as stream flow, groundwater levels, and snowpack and snowmelt. The team found that post-wildfire conditions resulted in greater winter snowpack and subsequently greater summer runoff as well as increased groundwater storage.

HPC Innovation Excellence Award Showcases Physics-based Scientific Discovery

A collaboration that includes researchers from NERSC was recently honored with an HPC Innovation Excellence Award for their work on “Physics-Based Unsupervised Discovery of Coherent Structures in Spatiotemporal Systems.” The award was presented in June by Hyperion Research during the ISC19 meeting in Frankfurt, Germany.

Designing Future Flash Storage Systems for HPC and Beyond

Glenn Lockwood from NERSC gave this talk at the Samsung Forum. “In this talk, we will compare the storage and I/O requirements of large-scale HPC workloads with those of the cloud and show how HPC’s unique requirements have led NERSC to deploy NVMe in the form of burst buffers and all-flash parallel file systems rather than block- and object-based storage. We will then explore how recent technological advances that target enterprise and cloud I/O workloads may also benefit HPC, and we will highlight a few remaining challenge areas in which innovation is required.”

NERSC Computer Scientist wins First Corones Award

Today the Krell Institute announced that Rebecca Hartman-Baker, a computer scientist at the Department of Energy’s (DOE’s) National Energy Research Scientific Computing Center (NERSC), is the inaugural recipient of the James Corones Award in Leadership, Community Building and Communication. “Hartman-Baker leads the User Engagement Group at NERSC, a DOE Office of Science user facility based at Lawrence Berkeley National Laboratory. A selection committee representing the DOE national laboratories, academia and Krell cited Hartman-Baker’s “broad impact on HPC training; her hands-on approach to building a diverse and inclusive HPC user community, particularly among students and early-career computational scientists; and her mastery in communicating the excitement and potential of computational science.”

ISC 2019 Recap from Glenn Lockwood

In this special guest feature, Glenn Lockwood from NERSC shares his impressions of ISC 2019 from an I/O perspective. “I was fortunate enough to attend the ISC HPC conference this year, and it was a delightful experience from which I learned quite a lot. For the benefit of anyone interested in what they have missed, I took the opportunity on the eleven-hour flight from Frankfurt to compile my notes and thoughts over the week.”

GPU Hackathon gears up for Future Perlmutter Supercomputer

NERSC recently hosted its first user hackathon to begin preparing key codes for the next-generation architecture of the Perlmutter system. Over four days, experts from NERSC, Cray, and NVIDIA worked with application code teams to help them gain new understanding of the performance characteristics of their applications and optimize their codes for the GPU processors in Perlmutter. “By starting this process early, the code teams will be well prepared for running on GPUs when NERSC deploys the Perlmutter system in 2020.”
