With APEX, National Labs Collaborate to Develop Next-Gen Supercomputers


Today Los Alamos, Lawrence Berkeley, and Sandia national laboratories announced the Alliance for Application Performance at Extreme Scale (APEX). The new collaboration will focus on the design, acquisition and deployment of future advanced technology high performance computing systems.

Cray, AMPLab, NERSC Collaborate on Spark Performance for HPC Platforms

This chart highlights portions of the BDAS stack (in red) that will be explored as a part of the Cray/AmpLab/NERSC collaboration.

Today NERSC announced a collaboration with UC Berkeley’s AMPLab and Cray to design large-scale data analytics stacks. “Analytics workloads will be an increasingly important workload on our supercomputers and we are thrilled to support and participate in this key collaboration,” said Ryan Waite, senior vice president of products at Cray. “As Cray’s supercomputing platforms enable researchers and scientists to model reality ever more accurately using high-fidelity simulations, we have long seen the need for scalable, performant analytic tools to interpret the resulting data. The Berkeley Data Analytics Stack (BDAS) and Spark, in particular, are emerging as a de facto foundation of such a toolset because of their combined focus on productivity and scalable performance.”

Users to Test DataWarp Burst Buffer on Cori Supercomputer


NERSC has selected a number of HPC research projects to participate in the center’s new Burst Buffer Early User Program, where they will be able to test and run their codes using the new Burst Buffer feature on the center’s newest supercomputer, Cori.

Cray Scales Fluent to 129,000 Compute Cores

Gas turbine combustor model using ANSYS Fluent involving complex physics including transient, turbulent flow, mixing of multiple chemical species and turbulence-chemistry interaction.

Today Cray announced a world record by scaling ANSYS Fluent to 129,000 compute cores. “Less than a year ago, ANSYS announced Fluent had scaled to 36,000 cores with the help of NCSA. While the nearly 4x increase over the previous record is significant, it tells only part of the story. ANSYS has broadened the scope of simulations allowing for applicability to a much broader set of real-world problems and products than any other company offers.”

Accelerating Science with SciDB from NERSC

Over at NERSC, Linda Vu writes that the SciDB open source database system is a powerful tool for helping scientists wrangle Big Data. “SciDB is an open source database system designed to store and analyze extremely large array-structured data—like pictures from light sources and telescopes, time-series data collected from sensors, spectral data produced by spectrometers and spectrographs, and graph-like structures that illustrate relationships between entities.”

Dr. Lewey reports on who’s jumping ship and moving on up in high performance computing.

Intelligent Light Scales CFD Code to 64,000 Cores


Today Intelligent Light announced breakthrough CFD scalability running the AVF-Leslie combustion simulation code on up to 64,000 cores on NERSC supercomputers.

Hunting Supernovas with Supercomputers

Caltech researchers are using NERSC supercomputers to search for newly born supernovas. The details of their findings appear May 20 in an advance online issue of Nature.

Fortran Still Going Strong


Fortran still going strong. NERSC estimates that over half the hours on their systems are used by Fortran codes. This is quite amazing, given that Fortran first appeared about 60 years ago.

NERSC to Install Cori Phase 1 Supercomputer this Summer


Today NERSC announced that their Cori Phase 1 system will be the first supercomputer installed in the new Computational Research and Theory Facility, which is now in the final stages of construction at LBNL. Expected to be delivered this summer, the Cray XC40 supercomputer will be powered by Intel Haswell processors and Cray’s DataWarp burst buffer technology.
