New automated tool 'debugs' nuclear weapon simulations

  • PDF
TechAndComputer (June 2, 2010) — Purdue University researchers, working with high-performance computing experts at Lawrence Livermore National Laboratory, have created an automated program to "debug" simulations used to more efficiently certify the nation's nuclear weapons.

The program, called AutomaDeD (pronounced like automated), finds errors in computer code for complex "parallel" programs.

"The simulations take several weeks to run, and then...

Could humans be infected by 'computer viruses?'

  • PDF
TechAndComputer (May 26, 2010) — A scientist at the University of Reading has become the first person in the world to be infected by a computer virus.

Dr Mark Gasson, from the School of Systems Engineering, contaminated a computer chip which had been inserted into his hand as part of research into human enhancement and the potential risks of implantable devices.

These results could have huge implications for implantable computing technologies used...

Software tool helps tap into the power of graphics processing

  • PDF
TechAndComputer (May 19, 2010) — Today's computers rely on powerful graphics processing units (GPUs) to create the spectacular graphics in video games. In fact, these GPUs are now more powerful than the traditional central processing units (CPUs) -- or brains of the computer. As a result, computer developers are trying to tap into the power of these GPUs. Now a research team from North Carolina State University has developed software that could...

Quantum move toward next generation computing

  • PDF
TechAndComputer (May 12, 2010) — Physicists at McGill University have developed a system for measuring the energy involved in adding electrons to semi-conductor nanocrystals, also known as quantum dots -- a technology that may revolutionize computing and other areas of science.

Dr. Peter Grütter, McGill's Associate Dean of Research and Graduate Education, Faculty of Science, explains that his research team has developed a cantilever force sensor...

Small mobile devices can serve as own computer mice with optical sensing method

  • PDF
TechAndComputer (Apr. 27, 2010) — The same inexpensive, but high-quality optical sensors employed in the common computer mouse can enable small mobile phones and digital music players to be used as their own pointing and gestural input devices, say researchers at Carnegie Mellon University's Human-Computer Interaction Institute (HCII).

By installing a pair of optical sensors on the back of a mobile phone or mp3 player, the researchers found that...
