IBM Applies Evolutionary Approach To Revolutionary Chip

IIBM has said that it will deliver an exascale chip within the next five years. The company made the annoucement less than two weeks after the U.S. Department of Energy's Argonne National Laboratory announced the creation of the Exascale Technology and Computing Institute (ETCi). Big Blue has also stated that the chip, based on new technology called CMOS Integrated Silicon Nanophotonics, can be produced on the front end of a standard CMOS manufacturing line and requires no new or special tooling

IBM has said that it will deliver an exascale chip within the next five years. The company made the annoucement less than two weeks after the U.S. Department of Energy's Argonne National Laboratory announced the creation of the Exascale Technology and Computing Institute (ETCi). Big Blue has also stated that the chip, based on new technology called CMOS Integrated Silicon Nanophotonics, can be produced on the front end of a standard CMOS manufacturing line and requires no new or special tooling. 

According to ETCi, exascale computing will create supercomputers that are 1,000 times more powerful than the world's current fastest system, China's Tianhe-1A. Exascale computing systems could achieve 1 million trillion floating point operations per second (exaflops). Today's current performance levels are measured in petaflops, a quadrillion operations per second.  

ETCi plans to address a variety of technical challenges over the next 10 years, including developing ultra-low power designs, 3-D chip configurations, massively parallel programming models, silicon photonics, and hybrid multicore architectures. However, it appears that IBM scientists have beaten ETCi to the punch with technology that integrates electrical and optical devices on the same piece of silicon. 

Enabling computer chips to communicate using pulses of light instead of electrical signals, will result in smaller, faster and more power-efficient chips. IBM says the technology enables a variety of silicon nanophotonics components, including modulators, germanium photodetectors and ultra-compact wavelength-division multiplexers. 

A single transceiver channel with all accompanying optical and electrical circuitry occupies only 0.5 mm. IBM wouldn't give a timetable on when the exascale technology will be delivered but did say that exascale computing would be available within the next five years.  View Full Bio

2014 Private Cloud Survey
Respondents are on a roll: 53% brought their private clouds from concept to production in less than one year, and 60% ­extend their clouds across multiple datacenters. But expertise is scarce, with 51% saying acquiring skilled employees is a roadblock.
