Scientists have just switched on the most powerful academic computer outside the US. The HPCx at Daresbury laboratory in Warrington, Cheshire -- the main lab of the government-funded research council -- has enough electronic brainpower to complete a full year's maths homework and classwork for every child in the UK in one fifth of a second.
When in full service, the US$84 million network of 1,280 powerful processors running in parallel will be able to undertake the hitherto undreamed of: model the air turbulence behind a jet as it lands, or the machinery of a cell as it manages the business of life.
The Daresbury installation ranks ninth in the world's top 500 supercomputer league table, and can handle 3.5 trillion number-crunching operations a second. According to Paul Durham, of Daresbury, it could one day accelerate medical research and cut costs at airports.
Precise satellite navigation and computer control could speed up traffic at airports and save on new runways. The wild card is the mysterious phenomenon of air turbulence.
Air traffic controllers allow time between takeoffs and landings because each jet plane leaves in its wake a tumble of vortices in the air. "They have to die down before the next one comes along, otherwise all hell breaks loose," says Durham. "Now if you could really do a model that shows what happens when a wake vortex hits the ground and bounces back up, you would be able to understand that, and try to design it out."
The computer will also be used to model once-unimaginable biological processes. Smaller computers can model individual enzymes, proteins and very complex things at the molecular level. But the next stage -- to model all the parts of a cell working together, the traffic of elements through cell membranes, and the behavior of the tiny organs within the cells- requires awesome processing power. The challenge is to mimic life in the act of sustaining itself.
"Some people talk of trying to make a virtual human," Durham said. "I think that is senseless. But could you make a virtual liver, and watch it processing alcohol? Yes. I am not saying we are going to do that tomorrow, but that is what we are going to build up to."
In theory, a silicon laboratory could eliminate at least some animal experiments. "That would be a goal," Durham said. "There is an awful lot to understand before we are at that stage, an awful lot. But yes, that is a goal."
Taiwan Transport and Storage Corp (TTS, 台灣通運倉儲) yesterday unveiled its first electric tractor unit — manufactured by Volvo Trucks — in a ceremony in Taipei, and said the unit would soon be used to transport cement produced by Taiwan Cement Corp (TCC, 台灣水泥). Both TTS and TCC belong to TCC International Holdings Ltd (台泥國際集團). With the electric tractor unit, the Taipei-based cement firm would become the first in Taiwan to use electric vehicles to transport construction materials. TTS chairman Koo Kung-yi (辜公怡), Volvo Trucks vice president of sales and marketing Johan Selven, TCC president Roman Cheng (程耀輝) and Taikoo Motors Group
Among the rows of vibrators, rubber torsos and leather harnesses at a Chinese sex toys exhibition in Shanghai this weekend, the beginnings of an artificial intelligence (AI)-driven shift in the industry quietly pulsed. China manufactures about 70 percent of the world’s sex toys, most of it the “hardware” on display at the fair — whether that be technicolor tentacled dildos or hyper-realistic personalized silicone dolls. Yet smart toys have been rising in popularity for some time. Many major European and US brands already offer tech-enhanced products that can enable long-distance love, monitor well-being and even bring people one step closer to
New apartments in Taiwan’s major cities are getting smaller, while old apartments are increasingly occupied by older people, many of whom live alone, government data showed. The phenomenon has to do with sharpening unaffordable property prices and an aging population, property brokers said. Apartments with one bedroom that are two years old or older have gained a noticeable presence in the nation’s six special municipalities as well as Hsinchu county and city in the past five years, Evertrust Rehouse Co (永慶房產集團) found, citing data from the government’s real-price transaction platform. In Taipei, apartments with one bedroom accounted for 19 percent of deals last
RECORD-BREAKING: TSMC’s net profit last quarter beat market expectations by expanding 8.9% and it was the best first-quarter profit in the chipmaker’s history Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), which counts Nvidia Corp as a key customer, yesterday said that artificial intelligence (AI) server chip revenue is set to more than double this year from last year amid rising demand. The chipmaker expects the growth momentum to continue in the next five years with an annual compound growth rate of 50 percent, TSMC chief executive officer C.C. Wei (魏哲家) told investors yesterday. By 2028, AI chips’ contribution to revenue would climb to about 20 percent from a percentage in the low teens, Wei said. “Almost all the AI innovators are working with TSMC to address the
