NEC claims supercomputer top spot

0 comments

NEC may have taken the lead in the supercomputer race, with the announcement yesterday of a machine capable of calculating 839 Teraflops – more than double the capacity of IBM's BlueGene/L, which clocks in a 280,6 Teraflops. A Teraflop is 1-trillion calculations per second. 

It's not yet clear whether the new Japanese computer will unseat IBM from the top of the list, since the theoretical capacity may not be reached in a live environment.
NEC's new SX-9 is designed for advanced science work, such as space science, environment simulations and meteorology.
The SX-90 is the latest in NEC's SX-series supercomputer line-up.
