From PC World:IBM is to build a hugely powerful supercomputer capable of performing at 20 petaflops per second, twenty times faster than the current record holder, namely the 1 petaflop Roadrunner machine it delivered back in June to Lawrence Livermore National Laboratory.
IBM has been contracted by the US government to build the machine, dubbed Sequoia, and is still developing the technology needed. It has also been asked to build a smaller computer called Dawn. Both machines will be constructed at its Blue Gene facilities in Rochester, Minnesota.
According to Big Blue, Sequoia will have the power of 2 million laptops. Its closest rival, the world's first petaflop machine, Roadrunner, can only perform at speeds equivalent to 100,000 laptops combined.
Understandably, a machine of this nature will occupy a lot room, namely 3,422 square feet (or 318 square metres). That is roughly the size of a large house, and although IBM claims it will be highly energy-efficient for the job it does, machines of this nature consume tremendous amounts of electricity and it is expected to occupy 96 refrigerator-sized racks.
