Record simulations conducted on Lawrence Livermore supercomputer Mar 19th 2013, 18:45 Researchers have performed record simulations using all 1,572,864 cores of Sequoia, the largest supercomputer in the world. Sequoia, based on IBM BlueGene/Q architecture, is the first machine to exceed one million computational cores. It also is No. 2 on the list of the world's fastest supercomputers, operating at 16.3 petaflops (16.3 quadrillion floating point operations per second). | Record simulations conducted on Lawrence Livermore supercomputer Mar 19th 2013, 18:45 Researchers have performed record simulations using all 1,572,864 cores of Sequoia, the largest supercomputer in the world.

Flash memory is a dominant technology in this field, but its slow writing and erasing speed has led to extensive research into a next-generation nonvolatile memory called Phase-Change Random Access Memory (PRAM), as PRAM's operating speed is 1,000 times faster than that of flash memory. Scientists have now developed a phase-change memory with low power consumption (below 1/20th of its present level) by employing self-assembled block copolymer silica nanostructures. | |
