Until fairly recently, Japan was the only country in the world with a definitive roadmap to its first exascale supercomputer. But over the last three months, specific plans for exascale systems in China, France, and the US have been revealed. If those schedules hold, between 2020 and 2023, all four countries will stand up their first exascale machines. The race to the next supercomputing milestone is finally starting to take shape.
IBM Research has demonstrated an advancement in phase change memory (PCM) that moves the technology closer to its potential of a “universal memory.” PCM is a technology that takes advantage of the unique amorphous-crystalline phase change properties of chalcogenide glass to store memory bits in a non-volatile manner. IBM has devised a unique variant that is able to store 3 bits of data per cell, enabling much denser storage arrays to be built.
HPC specialist DataDirect Networks (DDN) has introduced Flashscale, a new all-flash storage solution aimed broadly across the high performance computing, enterprise/big data, and web/cloud markets. DDN is positioning the product for “scale-up and scale-out” storage installations, which implies customers with extra-large data sets. It is DDN’s first pure flash offering and joins a growing list of such products from other storage vendors.
An article published this week in MIT Technology Review ponders the fate of the computing industry after Moore’s Law. The “law” is actually an observation made in 1965 by Intel cofounder Gordon Moore that transistors were shrinking with each iteration of semiconductor technology, doubling in density every year -- later modified to every 18 months, then to every two years.
