Supercomputing the Signature of Chaos in Ultracold Reactions

Researchers have performed the first ever quantum-mechanical simulation of the benchmark ultracold chemical reaction between potassium-rubidium (KRb) and a potassium atom, opening the door to new controlled chemistry experiments and quantum control of chemical reactions that could spark advances in quantum computing and sensing technologies. The research by a multi-institutional team simulated the ultracold chemical reaction, with results that had not been revealed in experiments. “We found that the overall reactivity is largely insensitive to the underlying chaotic dynamics of the system,” said Brian Kendrick of Los Alamos National Laboratory’s Theoretical Division, “This observation has important implications for the development of controlled chemistry and for the technological applications of ultracold molecules from precision measurement to quantum computing.”

Lenovo Gains Momentum in HPC at ISC 2017

In this video from ISC 2017, Rick Koopman from Lenovo describes the company’s innovative solutions for HPC. “Lenovo recently announced the delivery of one of the most powerful systems – among the first in the world based on Intel Xeon Platinum processor family – to Barcelona Supercomputing Center (BSC). The BSC MareNostrum 4 supercomputer, tasked with jobs in science and engineering research, incorporates 48 racks with more than 3,400 nodes with next generation Intel Xeon processors and a central memory of 390 Terabytes. Its peak power will be over 11 Petaflops.”

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.”

Brazil-Based AMT to Resell Bright Computing Software

Today Bright Computing announced a reseller agreement with AMT. “We are very impressed with Bright’s technology and we believe it will make a huge difference to our customers’ HPC environments,” said Ricardo Lugão, HPC Director at AMT. “With Bright, the management of an HPC cluster becomes very straightforward, empowering end users to administer their workloads, rather than relying on HPC experts.”

Agenda Posted for September HPC User Forum in Milwaukee

Hyperion Research has posted the preliminary agenda for the HPC User Forum Sept. 5-7 in Milwaukee, Wisconsin. “The HPC User Forum community includes thousands of people from the steering committee, member organizations, sponsors and everyone who has attended an HPC User Forum meeting. Our mission is to promote the health of the global HPC industry and address issues of common concern to users.”

ANSYS Scales to 200K Cores on Shaheen II Supercomputer

Today ANSYS, Saudi Aramco, and KAUST announced a new supercomputing milestone by scaling ANSYS Fluent to nearly 200,000 processor cores – enabling organizations to make critical and cost-effective decisions faster and increase the overall efficiency of oil and gas production facilities. This supercomputing record represents a more than 5x increase over the record set just three years ago, when Fluent first reached the 36,000-core scaling milestone. “Today’s regulatory requirements and market expectations mean that manufacturers must develop products that are cleaner, safer, more efficient and more reliable,” said Wim Slagter, director of HPC and cloud alliances at ANSYS. “To reach such targets, designers and engineers must understand product performance with higher accuracy than ever before – especially for separation technologies, where an improved separation performance can immediately increase the efficiency and profitability of an oil field. The supercomputing collaboration between ANSYS, Saudi Aramco and KSL enabled enhanced insight in complex gas, water and crude-oil flows inside a separation vessel, which include liquid free-surface, phase mixing and droplets settling phenomena.”

BSC Comparing Algorithms that Search for Cancer Mutations

Eduard Porta-Pardo from BSC has undertaken the first ever comparative analysis of sub-gene algorithms that mine the genetic information in cancer databases. These powerful data-sifting tools are helping untangle the complexity of cancer, and find previously unidentified mutations that are important in creating cancer cells. “Finding new cancer driver genes is an important goal of cancer genome analysis,” adds Porta-Pardo. This study should help researchers understand the advantages and drawbacks of sub-gene algorithms used to find new potential drug targets for cancer treatment.

Dell Builds Bracewell Supercomputer for Bionic Vision Research at CSIRO in Australia

Today CSIRO, Australia’s top science agency, announced deployment of a new Dell EMC supercomputer, kicking off a new generation of research in artificial intelligence. “This new system will provide greater scale and processing power we need to build our computer vision systems by optimization of processing over broader scenarios, represented by much larger sets of images, to help train the software to understand and represent the world. We’ll be able to take our computer vision research to the next level, solving problems through leveraging large scale image data that most labs around the world aren’t able to.” Assoc. Professor Barnes said.

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.”

Petabyte-Scale Active Archive in Private Object Storage

In big data science, storage archives protect massive volumes of research-critical content. Scientists at the University of Warsaw (UW) Interdisciplinary Centre for Mathematical and Computational Modelling (ICM) rely on a petabyte-scale active archive built on modern storage technology.
