Supercomputer Simulations Help Lay Foundation for Better, Greener Concrete

November 25, 2013 11:12 am | by Jim Collins, Argonne National Laboratory | Comments

NIST researchers are conducting simulations at the Argonne Leadership Computing Facility to advance the measurement science of concrete and to gain a fundamental understanding of how it flows. The NIST research team is combining data from large-scale simulations with theoretical work and physical experiments to create Standard Reference Materials (SRMs) for concrete to allow for more accurate viscosity measurements.


FDA’s Focus on Laboratory Data Integrity – Part 2

September 15, 2013 3:31 pm | by R.D. McDowall, Ph.D. | Comments

A further look at this current emphasis and a few problems inspectors have identified. The integrity of data generated by a regulated laboratory can make or break a regulatory inspection or audit. If you think that the warning letter citations quoted in part 1 of this article were bad, give a thought for another company...


FDA’s Focus on Laboratory Data Integrity – Part 1

September 10, 2013 3:04 pm | by R.D. McDowall, Ph.D. | Comments

The integrity of data generated by a regulated laboratory can make or break a regulatory inspection or audit. This paper looks at what is required for data integrity from the basis of the GMP regulations. It presents examples of non-compliances found in warning letters and a regulatory action from the U.S. Food and Drug Administraqtion (FDA).


Less is More: Adopting a Self-documenting Paperless Mindset

September 10, 2013 10:52 am | by Peter J. Boogaard | Comments

The paper versus paperless discussion is as old as the existence of commercial computers. In 1975, just after the introduction of the first personal computer Scelbi (SCientific, ELectronic and BIological), Business Week already predicted that computer records would soon completely replace paper. We all know that it took over 25 years before paperless operations were accepted and successfully adopted in our daily work.


Hardware for Big Data, Graphs and Large-scale Computation

September 9, 2013 9:58 am | by Rob Farber | Comments

Recent announcements by Intel and NVIDIA indicate that massively parallel computing with GPUs and Intel Xeon Phi will no longer require passing data via the PCIe bus. The bad news is that these standalone devices are still in the design phase and are not yet available for purchase.


Book Review: Applied Regression Modeling

September 1, 2013 5:47 pm | by John A. Wass, Ph.D. | Comments

It is always a pleasure to review a text that is easy to read and understand, when targeted to a novice audience. This book was written for business majors at the junior undergraduate level, and not statistics majors. However, it is recommended that readers have a course in introductory statistics before using this book.


The New Frontier of Biologics ELN

September 1, 2013 5:36 pm | by Michael H. Elliott | Comments

The rapid increase of investment in biotherapeutics is changing the profile of the biopharmaceutical industry and, along with it, data management in the laboratory. With attention on longer patent life, high barriers to generic equivalents and personalized medicine, an increasing portion of R&D spending is being allocated to large molecule therapies


Big Data Requires Scalable Storage Bandwidth

August 15, 2013 9:00 am | by Rob Farber | Comments

The adage that a supercomputer is a complicated device that turns a compute bound problem into an IO bound problem is becoming ever more apparent in the age of big data. The trick to avoid the painful truth in this adage is to ensure that the application workload is dominated by streaming IO operations.


Global Filesystem Delivers High Bandwidth, High Volume, Low Response Time

August 15, 2013 8:55 am | by Jon Bashor, LBNL | Comments

Discovery of the last neutrino mixing angle — one of Science magazine’s top 10 breakthroughs of the year 2012 — was announced in March 2012, just a few months after the Daya Bay Neutrino Experiment’s first detectors went online in southeast China. Collaborating scientists from China, the United States, the Czech Republic and Russia were thrilled that their experiment was producing more data than expected


At NERSC, Scalable Storage for Big Data Leads to Big Science Breakthroughs

August 15, 2013 8:49 am | by Jon Bashor | Comments

The U.S. Department of Energy’s National Energy Research Scientific Computing Center has a straightforward approach to data: When any of the center’s 4,500 users need access to their data, NERSC needs to be able to deliver. It’s an approach that’s worked well for 39 years and helps NERSC’s users annually publish more than 1,500 scientific papers.


HPC Architectures Begin Long-Term Shift Away from Compute Centrism

August 15, 2013 8:43 am | by Steve Conway, IDC | Comments

The HPC market is entering a kind of perfect storm. For years, HPC architectures have tilted farther and farther away from optimal balance between processor speed, memory access and I/O speed. As successive generations of HPC systems have upped peak processor performance without corresponding advances in per-core memory capacity and speed, the systems have become increasingly compute centric


Scalable Storage Solutions for Applied Big Data

June 20, 2013 4:35 pm | by Rob Farber | Comments

Considered in isolation, big data is nothing more than job security for tech vendors and system managers. Only through application can the value of big data be realized. For example, scraping the Internet for Web sites will clearly generate a big data set.


Big Data: It’s not Just Big

June 20, 2013 4:30 pm | by David Skinner | Comments

There is nothing new about data. It has existed as long as measurement itself. Many in the scientific community are then asking, “What is Big Data? And what’s new about it?” What’s new is our relationship to data. Attention to size, whether on tera-, peta-, or exabyte boundaries, is indeed important, but that’s not what Big Data is about.


Supercomputing: The Reality and Vision

June 20, 2013 4:27 pm | by Andrew Jones | Comments

The door to the research group tea-room swung open and Rebecca marched in. She smiled at the team members already there and announced joyfully, “the review committee approved the business case — we can buy our supercomputer!” One person cheered, another grinned widely. Most simply grunted “good,” “about time,” “well done” or similar minimal shows of enthusiasm — not truly believing they had been successful yet.


Texas Unleashes Stampede for Science

June 20, 2013 4:21 pm | by Aaron Dubrow | Comments

You hear it before you see it — a roar like a factory in full production. But instead of cars or washing machines, this factory produces scientific knowledge. Stampede, the newest supercomputer at the Texas Advanced Computing Center (TACC) and one of the most advanced scientific research instruments in the world, fills aisle after aisle of a new 11,000-square-foot data center at The University of Texas at Austin.
