The Top 500 list of the world’s fastest computers has just been announced. Not surprisingly, since it’s been reported on prior to the official announcement, the Chinese Tianhe-2 system tops the list. And that is an understatement. We talk with Jack Dongarra, Horst Simon, Hans Meuer and others from the….
How does the Phi coprocessor measure up to Xeon “Sandy Bridge” brand-mate?
Intel’s manycore wonder comes with its own programming challenges.
<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/Xeon_Phi_chip_small.jpg” alt=”” width=”96″ height=”79″ />With the recent introduction of Intel’s first Xeon Phi coprocessors, NVIDIA’s latest Kepler GPUs, and AMD’s new FirePro S10000 graphics cards, the competition for HPC chip componentry has entered a new phase. The three chipmakers have taken somewhat different paths, though, and it will be up to the market to decide which vendor’s approach will win the day.

The new products clock in at just over a teraflop, double precision, setting the stage for an HPC accelerator battle that will pit Intel against GPU makers NVIDIA and AMD. Both of those companies also released their latest HPC accelerators into the wild earlier today at the annual Supercomputing Conference in Salt Lake City.

When completed in 2013, the system will deliver one petaflop of performance and will take up residence in one of the most energy-efficient datacenters in the world.
Intel refines Knights Corner design as it prepares to go head-to-head against its GPU competition.
<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/knights_corner_chip.jpg” alt=”” width=”83″ height=”63″ />On Monday at the International Supercomputing Conference in Hamburg, Intel announced that Knights Corner, the company’s first manycore product, would be in production before the end of 2012. The company also released a few more details about the upcoming product line, including the creation of a new Xeon brand for the architecture, some performance updates on pre-production silicon, and Cray’s adoption of MIC as part of its future Cascade supercomputer.

Also released were a number of documents describing the processor’s micro-architecture, including the Knights Corner Instruction Set (ISA) Manual, which will help toolmakers and application developers build software for the upcoming chip.
