Adapteva Unveils 64-Core Chip

Aug 22, 2012 |

<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/Epiphany_64_small.JPG” alt=”” width=”99″ height=”90″ />Chipmaker Adapteva is sampling its 4th-generation multicore processor, known as Epiphany-IV. The 64-core chip delivers a peak performance of 100 gigaflops and draws just two watts of power, yielding a stunning 50 gigaflops/watt. The engineering samples were manufactured by GLOBALFOUNDRIES on its latest 28nm process technology.

The Last Mile of Virtualization

May 3, 2012 |

<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/exludus_logo.jpg” alt=”” width=”139″ height=”32″ />The advent of multicore servers presents something of a challenge for application virtualization. This is especially true in the realm of high performance computing, an environment that has never been particularly friendly to virtualization. To overcome these hurdles, eXludus Technologies has introduced “micro-virtualization,” a technology that brings virtualization down to the level of the core, and does so with minimal overhead.

Compilers and More: Exascale Programming Requirements

Apr 14, 2011 |

In his third column on programming for exascale systems, Michael Wolfe shares his views on what programming at the exascale level is likely to require, and how we can get there from where we are today. He explains that it will take some work, but it’s not a wholesale rewrite of 50 years of high performance expertise.
