SC13 Conference to Recognize Innovators

Supercomputing innovators will be honored with a new award at this year’s SC13 supercomputing conference in Denver. William Pugh of the University of Maryland will receive the inaugural “Test of Time” award for his 1991 paper, “The Omega Test: a Fast and Practical Integer Programming Algorithm for Dependence Analysis.” Continue reading

Japan Boosts Railway Simulation Capability

The Railway Technical Research Institute (RTRI) in Japan has added more muscle to its supercomputer infrastructure for complex railway simulations. The organization, which focuses on research and development of railway-related science and technology, has deployed a Cray XC30-AC supercomputer, Cray CS300 cluster supercomputer, and a Cray Sonexion storage system into production.


Computer Chip Will Mimic Human Brain

Technology has certainly gotten faster and smarter, but the human brain remains the clear champ when it comes to raw performance. We’ve written before about attempts to simulate brain function electronically; now researchers at Boise State University have launched a project to build a new computing architecture that mimics the brain called “CIF: Small: Realizing Chip-scale Bio-inspired Spiking Neural Networks with Monolithically Integrated Nano-scale Memristors.” Continue reading

New Research Improves Computer Memory by Tying it into Knots

Our daily lives are so busy that’s it’s easy to forget something. The most primitive solution to this dilemma is to tie a piece of string around a finger and knot it. In theory, every time you see the knot, you’ll remember what it is you’ve forgotten.

Researchers at the University of Hamburg have a plan to improve your computer’s hard drive memory by tying it into similar knots. In place of iron-based magnetics, which can fail at high temperatures, or if you attempt to store too much information, the scientists are working with knots of magnetic atoms called skyrmions.

Organic Electronics Get a Boost Through New Printing Process

In the movies, any time an alien race has technology based on organic processes, it’s inevitably sticky or gooey. As a kid, that kind of thing was gross. As an adult, it makes no sense. What kind of engineer, regardless of origin, is going to design a system that continually loses parts and gums itself up with every use, no matter how simple?

Fortunately for us, real organic electronics are neither sticky nor gooey, and now they may have gotten a boost in performance thanks to a new printing process. The U.S. Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have teamed up to improve the process responsible for building low-cost solar cells, flexible displays and a number of other electronics products.
