Last year, Khanna’s construction of a small supercomputer using eight Sony-donated Playstation 3 gaming consoles made headlines nationwide in the scientific community. On the consoles, he is solving complex equations designed to predict the properties of gravitational waves generated by the black holes located at the center of the galaxies. “Science budgets have been significantly [...]
When you enter the computer room on the second floor of Tokyo Institute of Technology’s computer building, you’re not immediately struck by the size of Japan’s second-fastest supercomputer. You can’t see the Tsubame computer for the industrial air conditioning units that are standing in your way, but this in itself is telling. With more than [...]
This post takes a look at the speed – latency and throughput – of various subsystems in a modern commodity PC, an Intel Core 2 Duo at 3.0GHz. I hope to give a feel for the relative speed of each component and a cheatsheet for back-of-the-envelope performance calculations. I’ve tried to show real-world throughputs (the [...]
Desktop supercomputers became a reality today as Nvidia announced the release of its new GPU-based Tesla personal supercomputer. Nvidia and its partners have announced today the availability of the new GPU-based Tesla personal supercomputer. The Tesla personal supercomputer is claimed to offer up to 250 times the performance of a standard PC or workstation, yet [...]
IBM has announced it will lead a US government-funded collaboration to make electronic circuits that mimic brains. Part of a field called “cognitive computing”, the research will bring together neurobiologists, computer and materials scientists and psychologists. As a first step in its research the project has been granted $4.9m (£3.27m) from US defence agency Darpa. [...]
Quantum mechanics describes how nature works at a fundamental level. Using those principles to build a quantum computer doesn’t just mean working at the nanoscale level; it also means keeping everything cold enough to see quantum effects. That’s why D-Wave runs its Orion system at a temperature 250 times colder than interstellar space. Last year [...]
UK researchers are working on fitting CCTV cameras with artificial intelligence, allowing them to more quickly respond to crimes. The technology, being developed by University of Portsmouth scientists, would allow cameras to “hear” violent sounds and react, swiveling quickly in the direction of a broken window or somebody shouting abusively for example, before alerting an [...]
The first laptops to make use of the SpursEngine, a multimedia co-processor derived from the Cell chip that powers the PlayStation 3, will go on sale in Japan in July. Toshiba will launch its Qosmio G50 and F40 machines with the chip, which contains four of the “Synergistic Processing Elements” from the Cell Broadband Engine [...]
Less than a week after Los Alamos National Laboratory’s Roadrunner supercomputer began operating at world-record petaflop/s data-processing speeds, Los Alamos researchers are already using the computer to mimic extremely complex neurological processes. Welcome to the new frontier of research at Los Alamos: science at the petascale. The prefix “peta” stands for a million billion, also [...]
IBM has announced an initiative to offer smaller versions of its high-performance computers to enterprise customers. The first new machine is a QS22 BladeCenter server powered by a Cell processor. Developed to power gaming systems, the Cell chip has also garnered interest from the supercomputing community owing to its ability to handle large amounts of [...]
