Women Who Compute: Overcoming Lack of Gender Diversity in Science and Technology

November 11, 2014 3:17 pm | by Rob Farber | Comments

Recent gender diversity reports from Google, Facebook and Apple (to name a few) have spurred a number of positive efforts to bring more women into computer science, including the SC14 Women in High Performance Computing workshop, NVIDIA’s Women who CUDA campaign, and Google’s $50M Women Who Code program.

HPC Matters to our Quality of Life and Prosperity

November 11, 2014 2:22 pm | by Don Johnston | Comments

The complexity of high-end computing technology makes it largely invisible to the public. HPC simply lacks the Sputnik sex appeal of the space race, to which current global competition in supercomputing is often compared. Rather, it is seen as the exclusive realm of academia and national labs. Yet, its impact reaches into almost every aspect of daily life. Organizers of SC14 had this reach in mind when selecting the “HPC Matters” theme.

A Focus on Code Modernization: Observing Year One of the Intel Parallel Computing Centers

November 10, 2014 11:11 am | by Doug Black | Comments

One year ago, recognizing a rapidly emerging challenge facing the HPC community, Intel launched the Parallel Computing Centers program. With the great majority of the world’s technical HPC computing challenges being handled by systems based on Intel architecture, the company was keenly aware of the growing need to modernize a large portfolio of public domain scientific applications, to prepare these critically important codes for multi-core

JMP 11: Remarkable Statistics, Graphics and Integration

November 7, 2014 10:30 am | by John A. Wass, Ph.D. | Comments

It should come as no surprise to readers of this column that JMP is a personal favorite and, along with SAS, one of my most-used programs. There are a number of reasons for this. Of the many advantages that most packages can offer, breadth and depth of the statistics offered, quality of the diagnostics, interconnectivity of graphics with both data and analyses, and ease-of-use issues are uppermost in my mind as most desirable.

Déjà Vu All Over Again: Knowledge management is not an IT problem, but a challenge to the culture of an organization

November 7, 2014 8:48 am | by Michael H. Elliott | Comments

In the late 1990s and the early 2000s, “Knowledge Management” (KM) was all the rage. Companies invested millions on enterprise content management (ECM) systems and teams of KM practitioners. It was believed that the codification of all knowledge assets across the enterprise would lead to new insights and higher levels of innovation.

Extending the Lifespan of Critical Resources through Code Modernization

September 9, 2014 2:05 pm | by Doug Black | Comments

As scientific computing moves inexorably toward the Exascale era, an increasingly urgent problem has emerged: many HPC software applications — both public domain and proprietary commercial — are hamstrung by antiquated algorithms and software unable to function in manycore supercomputing environments. Aside from developing an Exascale-level architecture, HPC code modernization is the most important challenge facing the HPC community.

Dramatically Intricate 3-D Universes Tell Important Stories about the Cosmos

August 21, 2014 3:16 pm | by Kelen Tuttle, Kavli Foundation | Comments

Recently, the Harvard-Smithsonian Center for Astrophysics unveiled an unprecedented simulation of the universe’s development. Called the Illustris project, the simulation depicts more than 13 billion years of cosmic evolution across a cube of the universe that’s 350-million-light-years on each side. But why was it important to conduct such a simulation?

Einstein vs Quantum Mechanics ... and Why He'd be a Convert Today

June 17, 2014 10:20 am | by Margaret Reid, Swinburne University of Technology | Comments

Albert Einstein's work laid down the foundation for modern quantum mechanics. His analysis of the “spookiness” of quantum mechanics opened up a whole range of applications, including quantum teleportation and quantum cryptography, but he wasn’t completely convinced by the theory of quantum mechanics — and that story is as fascinating as the theory he attempted to nail down. Quantum mechanics is downright bizarre...

Building Momentum for Code Modernization: The Intel Parallel Computing Centers

June 9, 2014 12:06 pm | by Doug Black | Comments

Like a Formula One race car stuck in a traffic jam, HPC hardware performance is frequently hampered by HPC software. This is because some of the most widely used application codes have not been updated for years, if ever, leaving them unable to leverage advances in parallel systems. As hardware power moves toward exascale, the imbalance between hardware and software will only get worse. The problem of updating essential scientific ...
