Video: Ramping up for Exascale at the National Labs

In this video from the Exascale Computing Project, Dave Montoya from LANL describes the continuous software integration effort at DOE facilities where exascale computers will be located sometime in the next 3-4 years. “A key aspect of the Exascale Computing Project’s continuous integration activities is ensuring that the software in development for exascale can efficiently be deployed at the facilities and that it properly blends with the facilities’ many software components. As is commonly understood in the realm of high-performance computing, integration is very challenging: both the hardware and software are complex, with a huge amount of dependencies, and creating the associated essential healthy software ecosystem requires abundant testing.”

nCorium Startup joins LANL’s Efficient Mission Centric Computing Consortium for Ultra-scale Efficiency

The San Jose-based startup company nCorium has joined Los Alamos National Laboratory’s Efficient Mission Centric Computing Consortium (EMC3) in the quest for efficient, ultra-scale computing. “We are excited to be working with nCorium to explore moving data multiple times faster than current approaches while adding value to the data as it moves,” said Gary Grider, HPC Division Leader at Los Alamos. “The prospect of using far less data movement/storage nodes in our environment while providing more in-flight data manipulation is an important step towards the higher efficiencies that the EMC3 seeks.”

Balancing the Load – A Million Cores in Concert

“If you’re doing any kind of parallel simulation, and you have a bit of imbalance, all the other cores have to wait for the slowest one,” Junghans says, a problem that compounds as the computing system’s size grows. “The bigger you go on scale, the more these tiny imbalances matter.” On a system like LANL’s Trinity supercomputer up to 999,999 cores could idle, waiting on a single one to complete a task.

Earth-modeling System steps up to Exascale

“Unveiled today by the DOE, E3SM is a state-of-the-science modeling project that uses the world’s fastest computers to more accurately understand how Earth’s climate work and can evolve into the future. The goal: to support DOE’s mission to plan for robust, efficient, and cost-effective energy infrastructures now, and into the distant future.”

Let’s Talk Exascale Podcast Looks at Co-Design Center for Particle-Based Applications

In this Let’s Talk Exascale podcast, Tim Germann from Los Alamos National Laboratory discusses the ECP’s Co-Design Center for Particle Applications (COPA). “COPA serves as centralized clearinghouse for particle-based methods, and as first users on immature simulators, emulators, and prototype hardware. Deliverables include ‘Numerical Recipes for Particles’ best practices, libraries, and a scalable open exascale software platform.”

Video: D-Wave Systems Seminar on Quantum Computing from SC17

In this video from SC17 in Denver, Bo Ewald from D-Wave Systems hosts a Quantum Computing Seminar. “We will discuss quantum computing, the D-Wave 2000Q system and software, the growing software ecosystem, an overview of some user projects, and how quantum computing can be applied to problems in optimization, machine learning, cyber security, and sampling.”

Podcast: The Exascale Data and Visualization project at LANL

In this episode of Let’s Talk Exascale, Scott Gibson discusses the ECP Data and Visualization project with Jim Ahrens from Los Alamos National Lab. Ahrens is principal investigator for the Data and Visualization project, which is responsible for the storage and visualization aspects of the ECP and for helping its researchers understand, store, and curate scientific data.

Trinity Supercomputer lands at #7 on TOP500

The Trinity Supercomputer at Los Alamos National Laboratory was recently named as a top 10 supercomputer on two lists: it made number three on the High Performance Conjugate Gradients (HPCG) Benchmark project, and is number seven on the TOP500 list. “Trinity has already made unique contributions to important national security challenges, and we look forward to Trinity having a long tenure as one of the most powerful supercomputers in the world.” said John Sarrao, associate director for Theory, Simulation and Computation at Los Alamos.

UCX and UCF Projects for Exascale Move Forward at SC17

In this video, Jeff Kuehn from LANL, Pavel Shamis from ARM, and Gilad Shainer from Mellanox describe progress on the new UCF consortium, a collaboration between industry, laboratories, and academia to create an open-source production grade communication framework for data centric and high-performance applications.

Video: An Affordable Supercomputing Testbed based on Raspberry Pi

In this video from SC17, Bruce Tulloch from BitScope describes a low-cost Rasberry Pi cluster that LANL can use to simulate large-scale supercomputers. “The BitScope Pi Cluster Modules system creates an affordable, scalable, highly parallel testbed for high-performance-computing system-software developers. The system comprises five rack-mounted BitScope Pi Cluster Modules consisting of 3,000 cores using Raspberry Pi ARM processor boards, fully integrated with network switching infrastructure.”
