The future is wireless. As we move toward total Wi-Fi coverage, the need for all those cables that burrow beneath the ground or hang just in range of falling trees will begin to diminish. Total coverage also means large areas need to be covered, so you never have to play the Wi-Fi version of, “Can you hear me now?”
DARPA is working on developing a long range Wi-Fi system that is capable of transferring data at up to 100 Gbps. The idea is to extend the range for communications with soldiers in the field, without slowing down the military’s wireless Common Data Link. Long range wireless would also assist the troops when they’re deployed to areas with limited, or no, infrastructure. Continue reading
As they improve, modern electronics have a way of shrinking. Unfortunately, their power requirements don’t decrease at the same rate. A lot of ongoing research is aimed at reducing the amount of energy required to run electronic devices. With that aim in mind, researchers at UCLA’s Henry Samueli School of Engineering and Applied Science have been developing a new type of memory that requires less energy than current technology.
According to the research team, the recently developed magnetoelectric random access memory (MeRAM) is up to 1,000 times more energy efficient than other types of memory, while retaining the high density, read speeds and other characteristics of current generation memory. Continue reading
It’s been a big year for nanophotonics, the technology that makes it possible to build chips that use pulses of light to communicate. A year ago we wrote about progress at MIT in developing photonic chips that use light beams to perform computational tasks. Now IBM has announced it has developed a scalable silicon nanophotonics chip on the path to enabling 100 Gpbs networks. Continue reading
I was at a party not too long ago to which someone had brought an old floppy disk drive (yes, my friends are also nerds). For laughs, I plopped down an iPhone on top of it. Keep that image in your mind as an example of how technology continues to shrink.
The Data Storage Institute (DSI) from Singapore’s Agency for Science, Technology and Research (A*STAR) has introduced a new hybrid they’ve dubbed the “A-Drive” that measures in at a sleek 5mm. The 1 TB hard disk is designed for use in equally thin laptops, such as Ultrabooks or a MacBook Air. Continue reading
Cray continues to push the boundaries of supercomputing. We previously wrote about the delivery of the Titan to Oak Ridge National Laboratory, and that system just nabbed the No. 1 spot on the Top500 list of the world’s fastest supercomputers. Titan (a Cray XK7) reached 17.59 petaflops on the Linpack benchmark, but Cray is already shipping systems that promise to leave Titan in the dust. The company has launched its next-generation XC30 supercomputer (previously code-named Cascade) that is designed to achieve HPC workloads of more than 100 petaflops and scale up to 1 million cores.
