Peta-Exa-Zetta: Robert Wisniewski and the Growth of Compute Power

While much noise is being made about the race to exascale, building productive supercomputers really comes down to people and ingenuity. In this special guest feature, Donna Loveland profiles supercomputer architect Robert Wisniewski from Intel. “In combining the threading and memory challenges, there’s an increased need for the hardware to perform synchronization operations, especially intranode ones, efficiently. With more threads utilizing less memory with wider parallelism, it becomes important that they synchronize among themselves efficiently and have access to efficient atomic memory operations. Applications also need to be vectorized to take advantage of the wider FPUs on the chip. While much of the vectorization can be done by compilers, application developers can follow design patterns that aid the compiler’s task.”

Basics For Coprocessors

“The Intel Xeon Phi coprocessor is an example of a many core system that can greatly increase the performance of an application when used correctly. Simply taking a serial application and expecting tremendous performance gains will not happen. Rewriting parts of the application will be necessary to take advantage of the architecture of the Intel Xeon Phi coprocessor.”

New Report Charts Future Directions for NSF Advanced Computing Infrastructure

A newly released report commissioned by the National Science Foundation (NSF) and conducted by National Academies of Sciences, Engineering, and Medicine examines priorities and associated trade-offs for advanced computing investments and strategy. “We are very pleased with the National Academy’s report and are enthusiastic about its helpful observations and recommendations,” said Irene Qualters, NSF Advanced Cyberinfrastructure Division Director. “The report has had a wide range of thoughtful community input and review from leaders in our field. Its timing and content give substance and urgency to NSF’s role and plans in the National Strategic Computing Initiative.”

Ron Perrott to Receive ACM Distinguished Service Award

Today ACM announced that Ron Perrott, an international leader in the development and promotion of parallel computing, will receive ACM’s prestigious Distinguished Service Award. The goal of ACM’s Awards and Recognition Program is to highlight outstanding technical and professional achievements and contributions in computer science and IT. Perrott will be formally honored at the ACM Awards Banquet on June 11 in San Francisco.

GCS in Germany Allocates Record Number of Core Hours for Research

The Gauss Centre for Supercomputing (GCS) in Germany has allocated a record 1,648 million core hours of computing time to 21 scientifically outstanding national research projects as part of its Call for Large-Scale Projects. “GCS is excited to support simulation projects of these excelling scopes as they clearly underline our claim of Germany being a world leader in High Performance Computing. Beyond dispute, they produce proof of us being at eye level with the largest international research projects such as the INCITE Program supported by the Office of Science of the U.S. Department of Energy,” states Prof. Thomas Lippert of JSC, GCS Chairman of the Board.”

Kick the Tires on Quantum Computing with the IBM Cloud

In its latest move to build a practical quantum computer, IBM Research for the first time ever is making quantum computing available in the cloud to anyone interested in hands-on access to the company’s advanced experimental quantum system. “The cloud-enabled quantum computing platform, called IBM Quantum Experience, will allow users to run algorithms and experiments on IBM’s quantum processor, work with the individual quantum bits (qubits), and explore tutorials and simulations around what might be possible with quantum computing.”

Video: A Journey to a Holistic Framework for Data-intensive Workflows at CSIRO

In this video from the 2016 MSST Conference, Ian Corner from CSIRO in Australia presents: A Journey to a Holistic Framework for Data-intensive Workflows. “At CSIRO, we are Australia’s national science organization and one of the largest and most diverse scientific research organizations in the world. Our research focuses on the biggest challenges facing the nation. We also manage national research infrastructure and collections.”

Supercomputing van der Waals Forces on Mira

Over at ALCF, Katie Jones writes that researchers are using the Mira supercomputer to validate a new “wave-like” model of the van der Waals force—a weak attraction that has strong ties to function and stability in materials and biological systems.

Video: DSSD Scalable High Performance FLASH Systems

Jeff Bonwick from EMC DSSD presented this talk at the MSST conference. “Jeff Bonwick is co-founder and CTO of DSSD, where he co-invented both the system hardware architecture and the Flood software stack. His talk will focus on extracting maximum performance from flash at scale. Jeff has a long history of developing at-scale storage starting with leading the team that developed the ZFS filesystem, which powers Oracle’s ZFS storage line as well as numerous startups including Nexenta, Delphix, Joyent, and Datto.”

Edison Supercomputer Helps Find Roots of MJO Modeling Mismatches

The MJO occurs on its own timetable—every 30 to 60 days—but its worldwide impact spurs scientists to unlock its secrets. The ultimate answer? Timely preparation for the precipitation havoc it brings—and insight into how it will behave when pressured by a warming climate.
