IDEAS Program Fostering Better Software Development for Exascale

Scalability of scientific applications is a major focus of the Department of Energy’s Exascale Computing Project (ECP) and in that vein, a project known as IDEAS-ECP, or Interoperable Design of Extreme-scale Application Software, is also being scaled up to deliver insight on software development to the research community.

Video: The DOE Exascale Computing Project

Doug Koethe from ORNL gave this talk at the HPC User Forum in Milwaukee. “The Exascale Computing Project (ECP) was established with the goals of maximizing the benefits of high-performance computing (HPC) for the United States and accelerating the development of a capable exascale computing ecosystem.”

Oak Ridge Turns to Deep Learning for Big Data Problems

The Advances in Machine Learning to Improve Scientific Discovery at Exascale and Beyond (ASCEND) project aims to use deep learning to assist researchers in making sense of massive datasets produced at the world’s most sophisticated scientific facilities. Deep learning is an area of machine learning that uses artificial neural networks to enable self-learning devices and platforms. The team, led by ORNL’s Thomas Potok, includes Robert Patton, Chris Symons, Steven Young and Catherine Schuman.

ORNL Readies Facility for 200 Petaflop Summit Supercomputer

Oak Ridge National Laboratory is moving equipment into a new high-performance computing center this month which is anticipated to become one of the world’s premier resources for open science computing. “There were a lot considerations to be had when designing the facilities for Summit,” explained George Wellborn, Heery Project Architect. “We are essentially harnessing a small city’s worth of power into one room. We had to ensure the confined space was adaptable for the power and cooling that is needed to run this next generation supercomputer.”

DOE Awards 1 Billion Hours of Supercomputer Time for Research

The DOE has awarded 1 Billion CPU hours of compute time on Oak Ridge supercomputers to a set important research projects vital to our nation’s future. ALCC allocations for 2017 continue in the tradition of innovation and discovery with projects awards ranging from 2 million to 300 million processor hours.

OpenACC Brings Directives to Accelerated Computing at ISC 2017

In this video from ISC 2017, Sunita Chandrasekaran and Michael Wolfe describe how OpenACC makes GPU-accelerated computing more accessible to scientists and engineers. “OpenACC is a user-driven directive-based performance-portable parallel programming model designed for scientists and engineers interested in porting their codes to a wide-variety of heterogeneous HPC hardware platforms and architectures with significantly less programming effort than required with a low-level model.”

Fernanda Foertter Elected SIG HPC Education Vice Chair

Today the Association for Computing Machinery’s Special Interest Group on High Performance Computing (SIGHPC) announced that Fernanda Foertter from ORNL is the new Vice Chair of the organization’s Education Committee. In this position, Foertter will support the goals of SIGHPC Education to promote increased knowledge and greater interest in the educational and scientific aspects of HPC. “Organizations such as SIGHPC broadens our periphery of other individuals within the HPC field. By connecting with my peers, I can make better decisions about what kinds of HPC training are needed and desired both within and outside of our own lab,” Foertter said.

Panel Discussion: Sustainable Software Development in Computational Sciences

“PASC has recently formed collaborative partnerships with a number of scientific journals. In this panel discussion, representatives from these journals are invited to express their thoughts regarding publication practices in the computational sciences, including the publication of software codes. How can we validate published results and guarantee reproducibility? Finally, we will describe our vision for the PASC papers initiative going forward.”

Red Hat Showcases ThunderX 2 Development Platform for HPC

In this video, Jon Masters from Red Hat describes the company’s multi-architecture solutions that were on display at ISC 2017. “Developing new and adapting existing highly scalable applications to take advantage of the new technological advances across multiple deployment domains is the greatest challenge facing HPC sites. This is where the operating system can provide a unified interface to the underlying hardware and interconnects and serve as a foundation for modular and standardized application stacks that take advantage of enhanced system capabilities.”

Thomas Zacharia named Director of Oak Ridge National Lab

Today UT-Battelle announced that Thomas Zacharia, who helped build Oak Ridge National Laboratory into a global supercomputing power, has been selected as the laboratory’s next director. “Thomas has a compelling vision for the future of ORNL that is directly aligned with the U.S. Department of Energy’s strategic priorities,” said Joe DiPietro, chair of the UT-Battelle Board of Governors and president of the University of Tennessee.
