Intel's New Omni Scale Fabric Platform: Taking on I/O Interconnect Challenges for Extreme-Scale HPC

June 27, 2014 | by Doug Black | Intel Corp | Comments

Even as CPU power and memory bandwidth march forward, a major bottleneck hampering overall supercomputing performance has presented a significant challenge over the past decade: I/O interconnectivity. The vision behind Intel’s new Omni Scale Fabric is to deliver a platform for the next generation of HPC systems.

Using Powerful GPU-Based Monte Carlo Simulation Engine to Model Larger Systems, Reduce Data Errors, Improve System Prototyping

July 22, 2014 8:33 am | by Jeffrey Potoff and Loren Schwiebert | Comments

Recently, our research work got a shot in the arm because Wayne State University was the recipient of a complete high-performance compute cluster donated by Silicon Mechanics as part of its 3rd Annual Research Cluster Grant competition. The new HPC cluster gives us some state-of-the-art hardware, which will enhance the development of what we’ve been working on — a novel GPU-Optimized Monte Carlo simulation engine for molecular systems.

Ethernet in the TOP500

July 11, 2014 8:16 am | by John D’Ambrosia | Comments

For the past 21 years, the TOP500.org has been ranking supercomputers by their performance on the LINPACK Benchmark. Reported two times a year, the release of the list is anticipated by the industry. As with any such ranking, the top of the list often garners the most attention. However, such emphasis on the top of such a list, would limit one’s understanding of the different supercomputers in the TOP500...

A Supercomputer with Warm Water. How Cool is That?

June 18, 2014 12:24 pm | by Peter ffoulkes, 451 Research | Comments

An energy efficient supercomputer with warm water.  How cool is that? Enlightenment has long been the ultimate pursuit of artists, philosophers, scientists, theologians and other sentient minds. Whether it is delivering the proof to support their theses, or to investigate a perplexing problem before them, they have poured a vast amount of energy into the situation. Energy has now become the problem.

Net Neutrality: No Demilitarized Zone

June 17, 2014 1:42 pm | by John R. Joyce, Ph.D. | Comments

Internet regulation in the United States is potentially facing a major change. FCC Internet Neutrality rules — also referred to as Net Neutrality rules — currently apply, but thanks to pressure from Internet Service Providers (ISP), legislators and recent court rulings, that might change. You have undoubtedly heard the term Net Neutrality before, but may be at a loss regarding what it means or what its implications are.

Who Are the Top500 List Countries?

June 16, 2014 10:01 am | by Gary M. Johnson, Computational Science Solutions | Comments

Since June of 1993, the Top500 List has been presenting information on the world’s 500 most powerful computer systems.  The statistics about these systems have proven to be of substantial interest to computer manufacturers, users and funding authorities.  While interest in the list is focused on the computers, less attention is paid to the countries hosting them.  Let’s take a look at the Top500 List countries.  Who are they?

High Performance Communication

June 9, 2014 10:12 am | by Tom Vander Aa, imec ExaScience Life Lab | Comments

In the late 90s, I was teaching parallel programming in C using MPI to students. The most important lesson I wanted them to remember is that communication is much more important than computation. The form of the benchmark couldn't be more common: a set of convolutional filters applied to an image, one filter after the other in a pipelined fashion.

Time Series Analysis: Identifying Underlying Patterns

June 5, 2014 12:07 pm | by Mark A. Anawis | Comments

Nelson Mandela said: “We must use time wisely and forever realize that the time is always ripe to do right.” Time series data have a temporal order that makes analysis distinctly different from other data analysis. The goal of time series analysis can be divided into characterization or prediction.

Ever since we started the Google self-driving car project, we’ve been working toward the goal of vehicles that can shoulder the entire burden of driving. Just imagine: You can take a trip downtown at lunchtime without a 20-minute buffer to find parking. Seniors can keep their freedom even if they can’t keep their car keys. And drunk and distracted driving? History.

The Evolving HPC Cluster: Big Compute meets Big Data

May 28, 2014 4:16 pm | by Gord Sissons, IBM | Comments

HPC systems have evolved significantly over the last two decades. While once the dominion of purpose-built supercomputers, today, clustered systems rule the roost. Horizontal scaling has proven to be the most cost-efficient way to increase capacity. What supercomputers all have in common today is their reliance on distributed computing.

On February 26, 2003, the National Institutes of Health released the “Final NIH Statement on Sharing Research Data.” As you’ll be reminded when you visit that link, 2003 was eons ago in “Internet time.” Yet the vision NIH had for the expanded sharing of research data couldn’t have been more prescient. As the Open Government Data site notes, government data is a tremendous resource that can have a positive impact on ...
