Alternatives Emerge as Linpack Loses Ground

Jun 18, 2013 |

Today at the International Supercomputing Conference in Leipzing, Germany, Jack Dongarra presented on a proposed benchmark that could carry a bit more weight than its older Linpack companion. The high performance conjugate gradient (HPCG) concept takes into account new architectures for new applications, while shedding the floating point….

We asked E4’s Simone Tinti, who leads the HPC team at E4, to describe the new systems and talk about the advantage they offer to high performance computing users.

Intel Brings Manycore x86 to Market with Knights Corner

Nov 12, 2012 |

<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/knights_corner_chip.jpg” alt=”” width=”98″ height=”85″ />Intel Corp. officially made its entry into the manycore realm today as it debuted “Knights Corner,” the company’s first Xeon Phi coprocessor. 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.

Cray Launches Cascade, Embraces Intel-Based Supercomputing

Nov 8, 2012 |

<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/Cray_XC30_small.jpg” alt=”” width=”95″ height=”86″ />AMD-loving Cray has launched the XC30 supercomputer, a product line that will be powered by Intel Xeon processors. The platform is based on the company’s “Cascade” architecture, which is designed to bring a variety of processors and coprocessors under a common infrastructure. XC will become Cray’s flagship computing platform as it phases out its XE and XK line over the next year or so.
