Oak Ridge National Laboratory’s TITAN is currently the world’s second fastest supercomputer. To ensure that the United States maintains a leadership position in High-Performance Computing (HPC) President Obama has issued an Executive Order establishing the National Strategic Computing Initiative (NSCI), whose charter will be to advance core technologies to solve difficult computational problems and foster increased use of these capabilities in the public and private sectors.   ...
If you’re a gearhead your idea of a fun video is watching a properly driven Ferrari, Lamborghini or Porsche blast off the line at a racetrack while onlookers calculate 0 to 60 mph acceleration times.  The Bugatti Veyron 16.4 Grand Sport Vitesse, for example, with over 1,000 horsepower on tap has been clocked doing 0-60 mph in just 2.4 seconds. Ferrari’s fastest, the La Ferrari reports in at 2.6 seconds for the 0 to 60 run and the recently upgraded Tesla Model S EV, operating in ...
With a performance of 33.86 petaflop/s (quadrillions of calculations per second) on the Linpack benchmark, Tianhe-2, a supercomputer developed by China’s National University of Defense Technology (Changsha, China), has retained its position as the world’s No. 1 supercomputer, according to the 43rd edition of the twice-a-year TOP500 list. The Linpack benchmark requires a computer to solve a dense system of linear equations. In second place was Titan, a Cray supercomputer based at the ...
Artist's impression of the JUICE mission to Jupiter   Even before the giddiness wears off from the successful New Horizons fly-by of Pluto space scientists are planning new explorations of the solar system. This week the European Space Agency (ESA) selected Airbus Defence & Space as its prime industrial contractor for the JUICE (JUpiter ICy moons Explorer) mission to Jupiter and its satellites: volcanic Io, icy Europa, rocky/icy Ganymede and Callisto. The contract covers the industrial ...
Are we there yet? After a nine-and-a-half year voyage the answer on July 14 will finally be “Yes!” as the New Horizons spacecraft passes just inside the orbit of Pluto’s moon Charon and to within 12,500 km (7,750 mi.) of the dwarf planet’s surface (when New Horizons launched from Cape Canaveral on Jan. 19, 2006 Pluto was considered a full-fledged planet, proving once again that a lot can happen in a decade).   The payload that this spacecraft carries is comprised o ...
With television content delivered largely via cable, satellite or the Internet (streaming media), it is easy to forget that the over-the-air television broadcast model is still a very efficient method of reaching large numbers of people, not only with entertainment programming but also, in times of emergencies, when you need a reliable means of disseminating critical information.   As broadcasters look to develop new services and evolve to accommodate the shifting viewing habits of the publ ...
With the population of mobile devices such as laptops and tablets increasing like jackrabbits on a fertility drug, organizations are increasingly implementing bring-your-own device (BYOD) policies in the workplace to gain a competitive edge and reduce costs. But the benefits of mobility can be lost if laptops and tablets are not adequately protected against security threats.   Recently a four-man team from Tel Aviv University’s LEISec (Laboratory for Experimental Information Security) ...
