Test Your Knowledge with the MPI Quiz

In this video, David Henty from EPCC conducts a video-based quiz on MPI. “The multiple-choice questions are partly designed for fun to test attendees’ knowledge, but are mainly aimed at promoting discussion about MPI and its usage in real applications. All that is assumed is a working knowledge of basic MPI functionality: send, receive, collectives, derived datatypes and non-blocking communications.”

HPC Analyst Crossfire at ISC 2017

In this video from ISC 2017, Addison Snell from Intersect360 Research fires back at industry leaders with hard-hitting questions about the state of the HPC industry. “Listen in as visionary leaders from the supercomputing community comment on forward-looking trends that will shape the industry this year and beyond.”

Video: Benchmarking AMD EPYC on Memory-Bound HPC Applications

In this video, Joshua Mora demonstrates how the new AMD EPYC processor delivers excellent performance for memory-bound HPC workloads including ANSYS and FLUENT. “EPYC strikes the perfect balance of cores/threads, memory, I/O bandwidth and security to deliver excellent performance for many High Performance Computing (HPC) workloads. AMD’s state-of-the-art GPUs combined with EPYC provide excellent solutions for your most demanding HPC applications.”

Video: Dark Matter – Detecting Gravity’s Hidden Hand

“One of today’s great challenges in physics is to observe individual dark matter particles coming in from the galaxy and striking particles on Earth. This talk presents the evidence for dark matter and introduces one of the most ambitious efforts to discover interactions of dark matter particles, using tons of cryogenic liquid in a deep underground laboratory.”

HPC Speeds NASCAR at OSC

In this video, Ray Leto from Total Sim LLC describes how his firm uses supercomputing resources at OSC to speed NASCAR simulations. “Designers and engineers utilizing common CAD or CAE software on desktop computers often encounter limitations in the modeling and simulation (M&S) they can efficiently perform. High Performance Computing provides an improvement in computational capacity compared to typical general-purpose computers. The increased power and speed that HPC provides allows more detailed models to be simulated faster.”

Supercomputing Ocean Currents at NASA

A team from the NASA has developed a new visualization tool that is being used by researchers from the Estimating the Circulation and Climate of the Ocean (ECCO) project to study the behavior of ocean currents. The new visualization tool provides high-resolution views of the entire globe at once, allowing the scientists to see new details that they had missed in previous analyses of their simulation, which was run on NASA’s Pleiades supercomputer.

Beating Floating Point at its own game: Posit Arithmetic

“Dr. Gustafson has recently finished writing a book, The End of Error: Unum Computing, that presents a new approach to computer arithmetic: the unum. The universal number, or unum format, encompasses all IEEE floating-point formats as well as fixed-point and exact integer arithmetic. This approach obtains more accurate answers than floating-point arithmetic yet uses fewer bits in many cases, saving memory, bandwidth, energy, and power.”

Video: HPE Powers 1 Petaflop QURIOSITY Supercomputer at BASF

“In today’s data-driven economy, high performance computing plays a pivotal role in driving advances in space exploration, biology and artificial intelligence,” said Meg Whitman, President and Chief Executive Officer, Hewlett Packard Enterprise. “We expect this supercomputer to help BASF perform prodigious calculations at lightning fast speeds, resulting in a broad range of innovations to solve new problems and advance our world.”

When Neutron Stars and Black Holes Collide

Working with an international team, scientists at Berkeley Lab have developed new computer models to explore what happens when a black hole joins with a neutron star – the superdense remnant of an exploded star. “If we can follow up LIGO detections with telescopes and catch a radioactive glow, we may finally witness the birthplace of the heaviest elements in the universe,” he said. “That would answer one of the longest-standing questions in astrophysics.”

Video: I/O Challenges in Brain Tissue Simulation

“Blue Brain Project simulations use mathematical models of individual neurons and synapses to compute the electrical activity of the network as it evolves over time. This requires a huge computational effort, only possible with large supercomputers. Simulations of larger volumes of tissue, at ever higher levels of detail, will need ever more powerful computing capabilities.”
