Video: Algorithms for Extreme-Scale Systems

Bill Gropp

Bill Gropp from the University of Illinois at Urbana-Champaign presented this talk at the Blue Waters Symposium. “The large number of nodes and cores in extreme scale systems requires rethinking all aspects of algorithms, especially for load balancing and for latency hiding. In this project, I am looking at the use of nonblocking collective routines in Krylov methods, the use of speculation and large memory in graph algorithms, the use of locality-sensitive thread scheduling for better load balancing, and model-guided communication aggregation to reduce overall communication costs. This talk will discuss some current results and future plans, and possibilities for collaboration in evaluating some of these approaches.”

Bringing ARM to the Student Cluster Competition

Over at the ISC Blog, Luna Backes writes that her Mont-Blanc Climbers Team is looking forward to building the first ARM-based cluster ever at the upcoming ISC Student Cluster Competition.

Video: Intel Vector Advisor Unlocks Code Performance

studio

In this video, Rick Leinecker from Slashdot Media describes the Vectorization Advisor, one of the new additions to Intel Parallel Studio XE suite. “Vectorization Advisor is an analysis tool that lets you identify if loops utilize modern SIMD instructions or not, what prevents vectorization, what is performance efficiency and how to increase it. Vectorization Advisor shows compiler optimization reports in user-friendly way, and extends them with multiple other metrics, like loop trip counts, CPU time, memory access patterns and recommendations for optimization.”

Slidecast: DDN Strategic Vision for High Performance Storage

Molly Rector, CMO and EVP of Product Management at DDN

“For more than a decade, DDN’s innovative, proven technology has been at the forefront of solving big data storage challenges in the world’s largest and most demanding environments,” said Molly Rector, CMO and EVP of Product Management at DDN. “Today, our vision and roadmap is being increasingly influenced by our enterprise and commercial HPC customers who are demanding new features in addition to the highest availability, reliability, scalability and best price/performance.”

Solar Superstorms Documentary Powered by Blue Waters

Solar_Superstorms

A new high-resolution science documentary about the dynamics of the Sun will feature data-driven supercomputer visualizations produced by NCSA. Narrated by Benedict Cumberbach, Solar Superstorms debuts June 30 at the Louisiana Art & Science Museum in Baton Rouge before heading out to more than a dozen planetariums and science centers around the world.

Addressing Climate Change Uncertainties with Petascale Computing

Donald J. Wuebbles, University of Illinois at Urbana-Champaign

“This collaborative research between the University of Illinois, the National Center for Atmospheric Research, and the University of Maryland is aimed at using the Blue Waters petascale resources to address key uncertainties associated with the numerical modeling of the Earth’s climate system and the ability to accurately analyze past and projected future changes in climate.”

Video: Supercomputing the Human Brain at Jülich

dirk

In this video, Prof. Dr. Dirk Pleiter from the Jülich Supercomputing Centre describes how Jülich is creating a 3D model of the human brain. “Jülich Supercomputing Centre, one of the largest research center in Germany, uses Lenovo Enterprise Systems to support research into a wide range of fields including neuroscience, fundamental physics, life sciences, climate change and energy.”

Video: Supercomputing Exoplanets

Erika Nesvold, UMBC

Astronomers Erika Nesvold (UMBC) and Marc Kuchner (NASA Goddard) essentially created a virtual Beta Pictoris in the computer and watched it evolve over millions of years. It is the first full 3-D model of a debris disk where scientists can watch the development of asymmetric features formed by planets, like warps and eccentric rings, and also track collisions among the particles at the same time.

Materials Discovery by Computation – a Revolution Still in the Making

aba274c131

“We will describe recent progress and successes obtained in predicting properties of matter by quantum simulations, and discuss algorithmic challenges in connection with the use of evolving high-performance computing architectures. We will also discuss open issues related to the validation of the approximate, first principles theories used in large-scale quantum simulations.”
