supercomputer Hits 93 Petaflop/s, Tripling Speed record

10 million-core supercomputer hits 93 petaflop/s, tripling speed record


There’s a new world’s fastest supercomputer for the first time in three years.

A Chinese supercomputer called Sunway TaihuLight now ranks as the world’s fastest, nearly tripling the previous supercomputer speed record with a rating of 93 petaflops per second. That’s 93 quadrillion floating point operations per second (or 93 million billion).


Sunway TaihuLight surpassed another Chinese supercomputer, Tianhe-2, which had been the world’s fastest for three consecutive years with speeds of 33.9 petaflop/s, according to the latest ranking released today. Top500 rankings are based on the Linpack benchmark, which requires each cluster “to solve a dense system of linear equations.”

New iPhone 7 Details Reveal 3 Radical Design Changes

Every other year Apple AAPL -1.90% changes the iPhone’s design, and following new leaks it appears 2016 could well produce the company’s most radical new iPhone to date…

Korea’s Commercial Times reports a trio of exciting changes are already being finalised for the iPhone 7 and all three look set to shake up the competition through a combination of innovation and – intriguingly – reviving a feature rivals discarded:

1. The iPhone 7 Will Be Waterproof

There has been speculation about this for some time and now it seems the smoke will indeed lead to fire: Apple is working hard to make the iPhone 7 completely waterproof.

In fairness the signs have been here for some time as an unmentioned ‘feature’ of the iPhone 6S and iPhone 6S Plus was the discovery they are virtually waterproof already. While I don’t recommend trying this for fear of voiding your warranty, tests have seen the handsets survive hours being fully submerged in water so taking one further step with the iPhone 7 makes a lot of sense. Just imagine the opportunity for underwater photography in Apple’s marketing.

So how would Apple take this final step? An obvious route would be to go through with growing reports that it will abandon the headphone jack – by far the deepest port in the iPhone and the hardest to waterproof. Whatever Apple’s route, however, the irony that rivals like Samsung had waterproof devices years ago then ditched the feature to more closely mimic Apple’s design aesthetic will not be lost on many.

Space Elevator with Inflatable Tower Patented by Thoth Technology

Space elevator with inflatable tower patented by Thoth Technology

Space cargo would travel up tower and launch from high altitude or low-Earth orbit


The top of a space elevator platform recently patented by Thoth Technology of Pembroke, Ont. is shown in this artist’s concept. The company thinks a 20-kilometre-high version could be built within 10 years.

Pembroke, Ont.-based Thoth Technology has patented an inflatable tower that could carry a “space elevator” higher than passenger jets fly – and eventually into low-Earth orbit.

The patent, which has been granted in the U.K. and the U.S. so far, describes a tower with a space launch platform on top that would initially be built to a height of around 20 kilometres high, but could theoretically be built to more than 200 kilometres high, and reach into low Earth orbit.


It would be made of stacked rings of Kevlar cells inflated with hydrogen or helium to an extremely high pressure. An elevator could ride up the tower, carrying spacecraft, satellites and other goods to be launched into space – along with tourists looking for an extraordinary view.

Carrying space cargo partway with an electric elevator would drastically reduce the amount of fuel needed to send such loads into space, says Brendan (Ben) Quine, the inventor behind the patent and Thoth Technology’s chief technical officer.

Right now, rockets carry extra fuel in containers called “stages” that drop off and fall into the ocean as the rocket gains altitude.


Launching from a 20-kilometre-high tower would cut the amount of fuel needed by a third and make the first stage of the rocket unnecessary, Quine said, making fully reusable spacecraft, including rockets and space planes, more practical.

Caroline Roberts, president and CEO of the company, which is also working on getting a Canadian patent, says the tower could work well with the reusable rocket technology that SpaceX is developing.

She also believe the 20-kilometre-high tower would be an attractive tourist destination.

“From the top of the tower looking out, you would be able to see the bright blue rim of the Earth and a view stretching 1,000 kilometres.”

The tower could also support massive wind turbines for power generation and be an alternative to satellites as a place to attach communications equipment.

Quine has already built a seven-metre-high scale model, which he unveiled in 2009 at York University in Toronto, where he is an associate professor.

Roberts says the company hopes to build a 1.5-kilometre-high prototype within five years – a height that would make it significantly higher than the current world’s tallest building, the 830-metre-tall Burj Khalifa in Dubai.

Roberts thinks a version that could reach 20 kilometres above sea level, starting from the top of a five-kilometre-high mountain, could be built with 10 years at a cost of about $5 billion US.

She added that Thoth is interested in partnering with companies that could help with construction of the prototype, including the developers of the world’s largest buildings.

Quine’s invention isn’t a traditional space elevator, an idea that has been kicking around since the late 19th century. The traditional concept consists of a fine cable with one end attached to weight in space, orbiting the Earth, and the other end tethered to the ground. The cable would be used as a track for attaching “climbers” carrying goods from one end to the other.

There are two challenges with that concept, Quine said:

  • It needs to be built in space.
  • The cable would be degraded by meteor and lightning strikes, and would have to be replaced every six months.

Thoth Technology’s elevator tower could be built from the ground up, and easily withstand not just lightning and meteors, but even category five hurricanes, Quine says.

In fact, the design includes gyroscopes to control the tower’s movement and actively stabilize it during major storms.

Self-climbing elevator

Quine envisions several possible ways to get the elevator up the tower.

The traditional cable used to raise most elevators wouldn’t be possible, since existing elevator cable materials couldn’t support 1.5 kilometres worth of their own weight. Scientists have proposed making space elevator cables out of a new, ultra-strong, high-tech material called carbon nanotubes, but “you can’t make cables out of carbon nanotubes that are rated for people yet,” Quine says.

One possibility is a “self-climbing” elevator attached to claws that reach three-quarters of the way around the tower and wheels underneath the claws to allow the elevator to spiral around the outside.

“My preference would definitely be to have them on outside because then you’d get the view,” Quine said. “The safety engineers are going to want it on the inside.”

While the company works on the Canadian patent, it is interested in talking to anyone around the world who is interested in licensing its technology and building the prototype, Quine says.
