China has build a new super computer which is about 74% faster than present fastest super computer at USA and Japan.Its name is given Tianhe-2 (also called Milkyway-2).

According to Computer World, the supercomputer can reach speeds of up to 54.9 petaflops. It has been built with Intel's chips, but also includes Chinese technology. The country's government has spent about $290 million building the computer.

It operates as fast as 30.7 petaflops - quadrillions of calculations per second.It runs Linux and has storage of 12.4 PB and memory of 1.4 PB.It also has 48,000 Xeon Phi chips, which is a co-processor based on Intel's Many Integrated Core architecture. Each of the Xeon Phi processors is capable of more than a Teraflop of speed.

Sony and Panasonic have announced that they're working together to develop the next generation optical discs. These discs will be capable of holding 300GB of data - considerably higher than the 50 GB that a dual-layer Blue-Ray can hold at  the moment - which can be read by standard players and hardware. Both companies believe that the discs will be ready for use by the end of 2015.

"Optical discs have excellent properties to protect them against the environment, such as dust resistance and water resistance and can also with stand changes in temperature and humidity when stored. They also allow inter-generational compatibility between different formats, ensuring that data can continue to read even as formats evolve. This makes them robust medium for long-term storage of content"said the jkoint press release from Sony and Panasonic.

"Both companies have previously developed products based on the Blu0ray format, leveranging the strength of optical discs. However, both Song and Panasonic recognized that optical discs will need to accomodate mucu larger volumes of storage in years to come given the expected furture growth in the archive marked and responded by formulating this agreement."

It's easy to understand why Sony wants to support the evolution with 4k content being critically important to irs 4k products since these discs will be capable of storing 4k movies.
