China Tops Top500 Supercomputing List

leave a comment »

For the first time ever, China has the most systems on the Top500 supercomputers list with 202, up from 159 six months ago.

By comparison, the U.S. dropped from 169 to 144, according to a report from CNET.

China also sits atop the Top500 list, with its Sunway TaihuLight supercomputer at China’s National Supercomputing Center in Wuxi reaching 93.01 petflops, or 93 quadrillion calculations per second.

But don’t rule out the U.S….

The United States might reclaim the top spot on the Top500 list, though. An IBM-built machine called Summit at Oak Ridge National Laboratory is designed to reach about 200 petaflops, double the performance of Sunway TaihuLight. It’s in a 10,000-square-foot facility that’s got a 20-megawatt power system for running the machine and keeping it cool. That’s enough electricity to power about 16,300 houses.

A Deal to Boost Mobile App Speeds

leave a comment »

ZDNet is reporting that web performance and security provider Cloudflare has acquired Neumob, a mobile accelerator for apps.

They report that Neumob will allow the company to provide improved end-to-end optimization across desktop and mobile, with no disruptions or speed loss based on the device used.

VentureBeat wrote of the deal:

Neumob’s technology is designed to replace traditional internet protocols that weren’t necessarily designed with the issues of wireless networks in mind, Cloudflare CEO Matthew Prince told VentureBeat. He said that TCP, one of the core protocols behind the internet, assumes that packet loss means there’s a router in a wired network being overwhelmed somewhere and backs off of transmitting data. “[That] makes a ton of sense on a wired network, but on a mobile network, when you start to see packet loss, that could just mean someone turned on the microwave or you’re driving through a tunnel, there are solar flares, or any number of things that the right reaction isn’t to back off,” Prince said. Neumob built a new set of capabilities that are designed to do away with issues like that. The technology is able to make applications load up to 3 times faster and reduce app errors and timeouts by up to 90 percent.
