Cat brain: A step toward the electronic equivalent
A cat can recognize a face faster and more efficiently than a supercomputer. That's one reason a feline brain is the model for a biologically-inspired computer project involving the University of Michigan.
Fujitsu develops world's fastest processor
(AP) -- Japanese computer maker Fujitsu Ltd. said Wednesday that it has successfully developed the world's fastest supercomputer processing unit with more than twice the speed of the current leader.
The power of graphics processing units may threaten the world’s password security system
It’s been called revolutionary - technology that lends supercomputer-level power to any desktop. What’s more, this new capability comes in the form of a readily available piece of hardware, a graphics processing unit ...
Physicists demonstrate the quantum von Neumann architecture
A new paradigm in quantum information processing has been demonstrated by physicists at UC Santa Barbara. Their results are published in this week's issue of Science Express online.
Research shows that it may be time to let software, rather than hardware, manage high-speed on-chip memory banks
In today's computers, moving data to and from main memory consumes so much time and energy that microprocessors have their own small, high-speed memory banks, known as "caches," which store frequently used ...
Researchers using parallel processing computing could save thousands by using an Xbox
(PhysOrg.com) -- A new study by a University of Warwick researcher has demonstrated that researchers trying to model a range of processes could use the power and capabilities of a particular XBox chip as a ...
Parallel course: Researchers help ease transition to parallel programming
(PhysOrg.com) -- In 1995, a good computer chip had a clock speed of about 100 megahertz. Seven years later, in 2002, a good computer chip had a clock speed of about three gigahertz -- a 30-fold increase. And ...
Speed limit on the quantum highway
(PhysOrg.com) -- Physicists at the Max Planck Institute of Quantum Optics have measured the propagation velocity of quantum signals in a many-body system.
Japan computer smashes speed record
A Japanese supercomputer has broken its own record as the world's fastest machine by performing 10 quadrillion calculations per second, its developers announced.
Chips as mini Internets
Computer chips have stopped getting faster. In order to keep increasing chips computational power at the rate to which weve grown accustomed, chipmakers are instead giving them additional cores, or ...
Hunt for extraterrestrial life gets massive methane boost
A powerful new model to detect life on planets outside of our solar system, more accurately than ever before, has been developed by UCL (University College London) researchers.
Detection of single photons via quantum entanglement
Almost 200 years ago, Bavarian physicist Joseph von Fraunhofer discovered dark lines in the sun's spectrum. It was later discovered that these spectral lines can be used to infer the chemical composition ...
