Physics Data Processed at NERSC Dramatically Cuts Reconstruction Time

In a recent demonstration project, physicists from Brookhaven National Laboratory and Berkeley Lab used the Cori supercomputer at the National Energy Research Scientific Computing Center to reconstruct data collected from a nuclear physics experiment, an advance that could dramatically reduce the time it takes to make detailed data available for scientific discoveries.

El Cerrito High School Students Get Hands-On Experience During Visit

Students from the IT Academy at El Cerrito High School recently took part in a special Big Data Study Trip hosted at the Lab and sponsored by Workforce Development and Education, EESA, NERSC, and CRD. They plotted characteristics and mapped patterns using water-quality data, and brainstormed on ways to collect and analyze data from San Pablo Bay. More>

Researchers Discuss Challenges of Storing and Retrieving Exascale Data

Future exascale supercomputers will be able to process a quintillion calculations per second. How can users store and retrieve data quickly enough on such a system? In this podcast, CRD’s Suren Byna and NERSC’s Quincey Koziol discuss prepping HDF5 – one of the most parallel I/O libraries for high-end supercomputing systems – for exascale use.

Lab Researchers Aid Speedier Scientific Data Flows

Eli Dart (ESnet), Michael Wehner (CRD), and Prabhat (NERSC) recently teamed up to document the data transfer workflow, data transfer performance, and other aspects of moving approximately 56 terabytes of climate data from the distributed Coupled Model Intercomparison Project (CMIP5) archive to NERSC.

Coupling Experiments to Theory to Build a Better Battery

A Berkeley Lab-led team of researchers has reported that a new lithium-sulfur battery component allows a doubling in capacity compared to a conventional lithium-sulfur battery, even after more than 100 charge cycles. More>

The Blob that Ate the Tokamak

To fuse hydrogen atoms into helium, devices called tokamaks must maintain the heat of the ultrahot plasma they control. But “boiling” plasma develops blobs that reduce the performance of the plasma. Analysis conducted at NERSC by researchers from Princeton Plasma Physics Lab has provided insight into how blobs at the plasma edge behave. More>

Heavy Metal: How First Supernovae Altered Early Star Formation

An international team of researchers ran multi-scale, multi-physics 2-D and 3-D simulations at NERSC to illustrate how heavy metals expelled from the universe’s first supernovae regulated subsequent star formation and influenced the appearance of galaxies in the process. More>

Detailed View of Immune Proteins Could Aid New Pathogen-Defense Strategies

Berkeley Lab biologists have resolved the structure of a ring of proteins used by the immune system for support when under attack, providing new insight into potential strategies for protection from pathogens. The researchers captured a high-resolution image of a protein ring as it was bound to flagellin, a protein from the tail used by bacteria to propel themselves forward. More>

A Spark in the Dark Universe

With help from NERSC, Fermilab is aiming Spark open-source software at data from high-energy physics. Spark, a data-reduction tool made for unstructured text files, is initially being put to work in the search for dark matter, but scientists hope that’s just the start. More>

NERSC Steps Up for ‘Inclusion Insights Game’

As part of the “Inclusion Starts With a Conversation” campaign sponsored by the Diversity, Equity, and Inclusion office, divisions are invited to watch videos and answer questions after viewing to score points. NERSC’s Rebecca Hartman-Baker tapped into the user facilities’ interest in friendly competition to aid their success. She shares her thoughts on making the most of this campaign here.
