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?

“There are just so many reasons why data sharing is important,” says Gary Berg-Cross, general secretary of the Spatial Ontology Community of Practice and a member of the US advisory committee for RDA.

Laying the Foundations for Better Sharing of Research Data

August 14, 2014 2:57 pm | by Andrew Purcell | Comments

The Research Data Alliance seeks to build the social and technical bridges that enable open sharing and reuse of data, so as to address cross-border and cross-disciplinary challenges faced by researchers. This September, the RDA will be hosting its Fourth Plenary Meeting. Ahead of the event, iSGTW spoke to Gary Berg-Cross, general secretary of the Spatial Ontology Community of Practice and a member of the US advisory committee for RDA.

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 ...

Do chromatography data systems (CDS) have adequate functions to help analytical scientists meet requirements when the pharmacopoeia is updated?

New CDS Functions to Meet New Regulatory Requirements?

June 5, 2014 4:17 pm | by R.D. McDowall, Ph.D. | Comments

A recent United States Pharmacopoeia (USP) stimulus to the revision process paper1 has taken a life cycle approach to the development, validation and use of analytical procedures. Do chromatography data systems (CDS) have adequate functions to help analytical scientists meet these requirements when the pharmacopoeia is updated?

Collaboration in the Cloud: Research Virtualization is Accelerating Market Evolution

June 5, 2014 12:39 pm | by Michael H. Elliott | Comments

The lack of a holistic data management environment to support virtualization has left project managers in a haze about how best to address the needs of the business. The sky is beginning to clear somewhat with recent introductions from companies such as Accelrys, Core Informatics and PerkinElmer. Those products, along with CDD, will be discussed to highlight capabilities and vendor approaches.

Hybrid cloud configurations provide the flexibility and cost benefits of the public cloud with the bandwidth, security and control of the private cloud.

Assessing Cloud ROI for HPC and Enterprise

June 5, 2014 12:26 pm | by Rob Farber | Comments

A complicated decision: To purchase infrastructure or run remotely in the cloud? Bandwidth and data security issues provide the easiest gating factors to evaluate, because an inability to access data kills any chance of using remote infrastructure, be it the public cloud or at a remote HPC center. If running remotely is an option, then the challenge lies in determining the return on investment (ROI) for the remote and local options ...

In summarizing this interesting book, it does have many useful hints, tips and tricks to addressing specific types of problems, as well as pitfalls. I would appreciate far more scientific examples than the business ones that were in abundance.

Doing Data Science: Straight Talk from the Front Line

June 5, 2014 11:53 am | by John A. Wass, Ph.D. | Comments

I can most simply describe this book by quoting from the back cover: Motivation — “…how can you get started in a wide-ranging, interdisciplinary field that’s so clouded in hype?” Background Needed — “If you’re familiar with linear algebra, probability, and statistics, and have programming experience…”

Recognizing ROI and Innovative Application of HPC

June 3, 2014 4:39 pm | by Chirag Dekate, Ph.D. | Comments

IDC initiated the HPC Innovation Excellence Award program in 2011 to recognize innovative achievements using high performance computing (HPC). While there are multiple benchmarks to measure the performance of technical computers, there have been few formats available to evaluate the economic and scientific value HPC systems contribute. The HPC Innovation Excellence Award Program is designed to help close that gap.
