IBM Reports Carbon Nanotube Transistor Breakthrough

Oct 1, 2015 |

Perhaps Moore’s law isn’t doomed just yet. Maybe. IBM Research (NYSE: IBM) reported in a paper in Science today a technique for making carbon nanotube transistors with tiny (~9nm) contacts that exhibit low, size-independent resistance. This overcomes a huge hurdle in shrinking transistor size beyond current limits. “I think this is the first carbon nanotube Read more…

Unmasking the Speed Limit of Modern Electronics

Dec 11, 2014 |

For the first time, scientists have captured the essence of semiconductor computing on film by taking snapshots of the electron transfer from valence to conduction band states. It is this leap that forms the basis for the entire semiconductor industry, digital electronics and modern computing as we know it. Using attosecond extreme ultraviolet (XUV) spectroscopy Read more…

Deconstructing Moore’s Law’s Limits

Aug 18, 2014 |

For the past five decades, computers have progressed on a predictable trajectory, doubling in speed roughly every two years in tune with Gordon Moore’s oft-cited observation-turned-prophecy. Although semiconductor scaling continues to yield performance gains, many perceive a tipping point is nigh, where the cost-benefit analysis of further miniaturization breaks down. The latest researcher to weigh Read more…

Novel Chip Technology to Power GRAPE-8 Supercomputer

May 10, 2012 |

<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/eASIC_logo_small.jpg” alt=”” width=”108″ height=”34″ />With the fastest supercomputers on the planet sporting multi-megawatt appetites, green HPC has become all the rage. The IBM Blue Gene/Q machine is currently number one in energy-efficient flops, but a new FPGA-like technology brought to market by semiconductor startup eASIC is providing an even greener computing solution. And one HPC project in Japan, known as GRAPE, is using the chips to power its newest supercomputer.

Cloud is History: The Sum of Trust

Jul 5, 2010 |

It is critical that there is a healthy cloud ecosystem for vendors and those who use their services, which can only be propelled by trust. The longevity of the cloud computing paradigm as a form of outsourcing critical applications depends on this ecosystem but trust can be easily compromised.
