Streamlining for speed with InfiniBand technology Kevin Shinpaugh, Ph.D. Long accepted as an article of faith within the high-tech industry, Moore's Law (CPU performance doubles every 18 months, while the cost of components halves) brings many blessings, yet it also presents a special set of challenges as far as harnessing increased CPU horsepower to other components of the system. Today, a "nothing-special" desktop computer bought from a...
A closer look at the most powerful commercially available computer systems The TOP500 project was started in 1993 to provide a reliable basis for tracking and detecting trends in high- performance computing. Twice a year, a list of the sites operating the 500 most powerful computer systems is assembled and released. Take a closer look at profiles of the top 10 systems appearing on the 25th TOP500 List released during ISC2005
Effective management and analysis of electronic data has become a crucial determinant of success or failure Trevor W. Heritage In pursuit of new drugs, pharmaceutical and biotechnology companies are today generating staggering amounts of data through the application of technologies such as high-throughput screening and parallel chemical synthesis. While data management systems are able to cope with the volume of data, serious challenges are...
In retrospect, I was probably distracted by some petty work issues when I returned to my apartment that evening in 1978. It was just twilight, and I was in a deep funk, staring at the ground as I walked from my car toward the apartment entrance.
The latest installment of my crusade to bring the biologists and mathematicians/statisticians together was given a small assist from a very interesting and scientifically "hot" area known as toxicogenomics. Recently, Morgan et. Al . had published a paper entitled "Complementary Roles for Toxicologic Pathology and Mathematics in Toxicogenomics
An early innovator shares his insights and vision for the future of mathematics Scientific Computing recently caught up with Charles "Chuck" W. Johnson, an early mathematics innovator, MIT alumni and Corporation Development Committee member, and founder of Visual Numerics (formerly IMSL). During our exchange, Chuck talked about his role in evolving mathematics and statistics into mainstream business analytics, as well as the profound changes the...
A look at three emerging data reduction techniques that allow scientists to use data acquired from existing dynamic systems to rapidly generate mathematical models Paul Goossens Data and numbers drive engineering and science and, over the past decades, we have accumulated a vast range of software and hardware tools to efficiently gather and analyze immense datasets. But is data enough? Increasingly, industry is realizing that data supported by...
This is a program you may hate the first few hours and love forever after John A. Wass, Ph.D. Unscrambler is specifically directed to multivariate analysis and experimental design, with emphasis on problems in chemistry and industrial production. It is one of the more unusual packages that I have seen in terms of its logic and, in this regard, may be a welcome change
Quantum imaging with magnetic resonance force microscopy Bill Weaver, Ph.D. The amount of force required to press the keys of a computer keyboard is around 1 newton (N). That’s about the force provided by a pad of Post-it notes as it mistakenly rests on your spacebar, filling the buffer until your computer emits a barrage of clicks for help. On the high side of things, the world-record holder
Easy solutions for connecting to a USB port Thomas Lutz Although USB stands for “universal serial bus,” the USB interface does not work anything at all like a standard RS232 serial port. Like RS232 serial ports, the USB ports on a PC are designed for interfacing external devices. However, any piece of equipment that is designed to connect to a USB port must come with a Windows device driver that essentially informs
No! Calm down, this isn't going to be a nihilist diatribe, I have something much more concrete in mind — data validation, in fact. Hang in there, you'll see the connection soon. The bane of the laboratory is data entry errors. These can take many forms, sometimes they are simple transcription errors, sometimes it is a substitution error, where one character is mistaken
Remembering Digital’s Ken Olsen Randy C. Hice My boss, Doug, had witnessed another member of our unit make insulting comments to me during a unit meeting. He asked me into his office the next day to compliment my restraint. “I would have expected you to retaliate in the meeting, you really are maturing
MINITAB features extensive graphical enhancements. advances expanded and simplified graph creation and editing, enhanced appearance of graphs, plus many new options to increase graph flexibility.
