Exascale rising!

Exascale Computing Project awards .8 million for application development

First investments made by recently formalized project

Improved computer climate models of the Earth’s clouds and more accurate simulations of the combustion engine are goals for two projects led by Sandia that were funded in the first round of grants from DOE’s break-out $39.8 million Exascale Computing Project (ECP).

Sandia also will conduct research with other laboratories on three exascale projects whose goals range from developing physics models for more efficient wind energy production to improving understanding of materials at the molecular level, and simulating quantum mechanical effects in materials.

The 22 projects chosen by the ECP were selected for their societal significance and their ability to advance through exascale computing.

Jackie Chen (8351) leads one of 15 fully funded projects: Transforming Combustion Science and Technology with Exascale Simulations. Mark Taylor (1446), chief computational scientist for DOE’s Accelerated Climate Modeling for Energy executive council, will lead a project titled Cloud-Resolving Climate Modeling of the Earth’s Water Cycle.

Other projects supported by Sandia computer scientists, engineers, and other researchers include Exascale Predictive Wind Plant Flow Physics Modeling, led by the National Renewable Energy Laboratory, with Oak Ridge National Laboratory and the University of Texas, Austin, as partners; Molecular Dynamics at the Exascale: Spanning the Accuracy, Length, and Time Scales for Critical Problems in Materials Science, led by Los Alamos National Laboratory, with the University of Tennessee; and QMCPACK: A Framework for Predictive and Systematically Improvable Quantum Mechanics-Based Simulations of Materials, led by Oak Ridge National Laboratory and five partners.

A billion billion calculations per second

Exascale refers to the next challenge in high-performance computing systems: machines capable of at

least a billion billion calculations per second, 50 to 100 times faster than the most powerful supercomputers in use today.

All 15 fully funded projects and seven others that received seed funding involve partners from a total of 45 universities, national labs, and private companies.

Says Bruce Hendrickson, director of Sandia’s Center for Computing Research (1400), “We are excited by the opportunity to lead DOE’s efforts in these critical areas of science and technology. Sandia is committed to the ECP’s goal of enhancing the impact of advanced computing through breakthroughs in computer science, software, and algorithms as well as hardware.”

Says Jackie, “The development of an exascale high-fidelity combustion simulation capability has tremendous potential scientific, technological, and societal impact. Due to the unrivaled energy density of liquid hydrocarbon fuels, combustion will continue to provide much of the world’s energy for at least the next 50 years. Combustion needs to be understood and optimized to prevent further climate change, to reduce emissions harmful to human health, and to ensure US energy security.”

Multi-decade climate simulations

Says Mark, “Our project team will develop a cloud-resolving Earth system model for multi-decade climate simulations that realistically treat storms. This will improve our ability to assess regional impacts of climate change on the water cycle that directly affect multiple sectors of the US and global economies, especially agriculture and energy production.”

 “These application development awards are a major first step toward achieving mission critical application readiness on the path to exascale,” says ECP director Paul Messina. “A key element of the ECP’s mission is to deliver breakthrough high-performance computing modeling and simulation solutions that confidently deliver insight and predict answers to the most critical US problems and challenges in scientific discovery, energy assurance, economic competitiveness, and national security.”

He continues, “Application readiness is a strategic aspect of our project and foundational to the development of holistic, capable exascale computing environments.”

The application efforts will help guide DOE’s development of a US exascale ecosystem as part of President Barack Obama’s National Strategic Computing Initiative (NSCI). DOE, the Department of Defense and the National Science Foundation have been designated as NSCI lead agencies, and the ECP is the primary DOE contribution to the initiative.

The ECP’s multiyear mission is to maximize the benefits of high-performance computing for US economic competitiveness, national security, and scientific discovery. In addition to applications, the ECP addresses hardware, software, platforms and workforce development needs critical to the effective development and deployment of future exascale systems.

The ECP will fund projects in energy security, economic security, scientific discovery, climate and environmental science, and healthcare. It is led by six DOE national laboratories: the Office of Science’s Oak Ridge, Argonne, and Lawrence Berkeley national labs, and NNSA’s Lawrence Livermore, Los Alamos, and Sandia national labs.

Developing a broad set of modeling and simulation applications that support the DOE’s scientific, engineering, and nuclear security programs is one of four primary ECP goals. Its other major goals are to develop productive exascale computing (hardware and software); prepare two or more DOE facilities to house exascale machines by 2023; and to maximize the benefits of high-performance computing to US science and commerce.
