TechAndComputer (Dec. 16, 2010) The rapid advances in information technology that drive many sectors of the U.S. economy could stall unless the nation aggressively pursues fundamental research and development of parallel computing -- hardware and software that enable multiple computing activities to process simultaneously, says a new report by the National Research Council. Better options for managing power consumption in computers will also...

TechAndComputer (Dec. 1, 2010) Quantum information processing is arguably one of the most fascinating facets of modern quantum physics. A quantum computer operates with quantum bits (qubits) as units of information. Obeying the laws of quantum mechanics, such a computer would be capable of addressing several of the most difficult computational tasks unsolvable with present technology. In the past few decades, scientists learned to perform...

TechAndComputer (Nov. 29, 2010) Researchers from North Carolina State University and IBM have invented a way to update computer systems packaged in virtual machines in a computer "cloud" -- even when those programs are offline.
The new cloud computing patch tool developed by NC State and IBM is called Nuwa and protects virtual machines (VMs) from cyber-attacks by ensuring that they always receive important security upgrades. In addition, the...

TechAndComputer (Nov. 25, 2010) Electrical engineers generated short, powerful light pulses on a chip -- an important step toward the optical interconnects that will likely replace the copper wires that carry information between chips within today's computers. University of California, San Diego electrical engineers recently developed the first ultra compact, low power pulse compressor on a silicon chip to be described in the scientific...

TechAndComputer (Nov. 19, 2010) Accelerator-based supercomputers hold eight of the top 10 spots on The Green500 List, just released. These supercomputers use dedicated hardware to perform computations faster than a typical central processing unit (CPU).
Accelerators also topped the June edition of the Green500 List. "One might argue that this year's Green500 marks The Year of the Accelerator," said Green500 co-founder Wu Feng, an associate...
