Developer Access Program for Intel® Xeon Phi™ Processor codenamed Knights Landing

Intel is bringing to market, in anticipation of general availability of the Intel® Xeon Phi™ Processor (codenamed Knights Landing), the Developer Access Program (DAP). DAP is an early access program for developers worldwide to purchase an Intel Xeon Phi Processor based system.

  • OMP Helper thread - binds or doesn't?

    In the OMP Runtime we have a helper thread.  My customers are asking where this thread is bound (or is it bound?) when using KMP_AFFINITY and a proclist.  To make it simple, assume the proclist is 1,2,3,4.  And OMP_NUM_THREADS=4.  Pretty obvious where the worker threads get bound.  What about the helper?  Empirically on a HSW Cray XC-40 the customer is reporting seeing the helper bound to proc 2.  Which surprised me.  I would have thought proc 1.  OR is it that the helper doesn't bind and floats within the proclist?

    Webinar: Programmer's Guide to Knights Landing

    The Intel’s next generation Xeon Phi™ processor family x200 product (code-name Knights Landing) brings in several new technological solutions: socket form-factor (stand-alone CPU), as well as coprocessor version; a high bandwidth on package memory called Multi-Channel DRAM (MCDRAM) in addition to the traditional DDR4, which leads to three modes of MCDRAM operation - cache, flat, and hybrid; optional integrated high-speed fabric;

    Whatever the Weather: The Intel Five Step Framework for Code Modernization

    Weather forecasting is a crucial aspect of modern life, enabling efficient planning and logistics, while also protecting life and property through timely warnings of severe conditions. But accurate, long-range weather prediction is extremely complex, often involving enormous data sets and requiring code that is optimized to leverage the most advanced computer hardware features available.
