On-Chip Device Accelerates Core-to-Core Communication

Sep 13, 2016 |

A team of engineers from North Carolina State University and Intel have joined forces to address on-chip communications bottlenecks that hamper performance scaling for workloads that share data frequently. Their paper, “CAF: Core to Core Communication Acceleration Framework,” describes a novel core-to-core Communication Acceleration Framework (CAF). The technique could provide relief for many HPC applications Read more…

Why 2016 Is the Most Important Year in HPC in Over Two Decades

Aug 23, 2016 |

In 1994, two NASA employees connected 16 commodity workstations together using a standard Ethernet LAN and installed open-source message passing software that allowed their number-crunching scientific application to run on the whole “cluster” of machines as if it were a single entity. Their do-it-yourself, McGyver-like efforts were motivated by a frustration with the pricing, availability Read more…

Mellanox Spins EZchip/Tilera IP Into BlueField Networking Silicon

Jun 1, 2016 |

Mellanox today introduced the BlueField family of programmable processors, the first product technology based on its $811 million acquisition of fellow Iraeli high-tech company EZchip. The fact that the product announcement is taking place just three months after the completion of the purchase speaks to the strong synergies between EZchip and Mellanox, said Bob Doud, senior director of marketing at Mellanox.

James Reinders: Parallelism Has Crossed a Threshold

Feb 4, 2016 |

Is the parallel everything era here? What happens when you can assume parallel cores? In the second half of our in-depth interview, Intel’s James Reinders discusses the eclipsing of single-core machines by their multi- and manycore counterparts and the ramifications of the democratization of parallel computing, remarking “we don’t need to worry about single-core processors anymore Read more…

Processor Diversity on the Rise, Reports Intersect360

Nov 12, 2015 |

Intel x86 processors continue to dominate HPC servers while the number of cores per processor also keeps rising, perhaps no surprises there. Also somewhat anticipated, the amount of memory per core, per processor, and per node is rising. These are the top line results of Intersect360 Research’s latest HPC sites survey on processor use. A Read more…

OpenACC Reviews Latest Developments and Future Plans

Nov 11, 2015 |

This week during the lead up to SC15 the OpenACC standards group announced several new developments including the release and ratification of the 2.5 version of the OpenACC API specification, member support for multiple new OpenACC targets, and other progress with the standard. “The 2.5 specification addresses an essential challenge of profiling code where a Read more…

Blacklisting Doesn’t Slow Intel Investment in China

Apr 28, 2015 |

Intel may be barred from selling leading edge technology to China’s top supercomputer sites but it is nonetheless ramping up its high-end collaboration with China. On April 21st, Intel launched the first Intel Parallel Computing Center in China, a joint effort with the Chinese Academy of Sciences (CAS), with widely publicized ceremonies in China. “This Read more…

A Comparison of Heterogeneous and Manycore Programming Models

Mar 2, 2015 |

The high performance computing (HPC) community is heading toward the era of exascale machines, expected to exhibit an unprecedented level of complexity and size. The community agrees that the biggest challenges to future application performance lie with efficient node-level execution that can use all the resources in the node. These nodes might be comprised of Read more…

Practical Advice for Knights Landing Coders

Feb 5, 2015 |

The National Energy Research Scientific Computing Center (NERSC) is on track to get its next supercomputer system, Cori, by mid-2016. While that’s more than a year away, it’s not too soon to start preparing for the new 30+ petaflops Cray machine, which will feature Intel’s next-generation Knights Landing architecture. So says Richard Gerber, Senior Science Read more…

Scalable Priority Queue Minimizes Contention

Feb 2, 2015 |

The multicore era has been in full-swing for a decade now, yet exploiting all that parallel goodness remains a prominent challenge. Ideally, compute efficiency would scale linearly with increased cores, but that’s not always the case. As core counts are only set to proliferate across the computing spectrum, it’s an issue that merits serious attention. Researchers from Read more…
