Choosing the right threading framework

This is the second article in a series of articles about High Performance Computing with the Intel Xeon Phi. The Intel Xeon Phi is the first commercial product of Intel to incorporate the Many Integrated Core architecture. In this article I will present various frameworks for unleashing the power of multiple threads on the Xeon Phi. We will also have a look at interesting properties and advantages / disadvantages of each framework.

  • Speeding Up Your Cloud Environment On Intel® Architecture

    In my previous blog, I discussed “Ways to Speeding up Your Cloud Environment…”, I will continue with this thread by introducing the topic of Software Defined Networks (SDN).  The industry has been depending on proprietary networking equipment and appliances, essentially creating an environment requiring vertical integrated software running on dedicated hardware.

    Measuring performance in HPC

    This is the first article in a series of articles about High Performance Computing with the Intel Xeon Phi. The Intel Xeon Phi is the first commercial product of Intel to incorporate the Many Integrated Core architecture. In this article I will present the basics of the Xeon Phi architecture, the programming models and what we can do to measure the performance in cycles for micro benchmarks.

  • Tuning the Intel MKL DFT functions performance on Intel® Xeon Phi™ coprocessors

    Overview

    Intel® Math Kernel Library (Intel® MKL) includes the optimized DFT transform functions on Intel® Xeon Phi™ coprocessors. These functions are carefully vectorized and threaded to take advantage of the hardware features. This article provides some performance tuning tips on running MKL DFT function on Intel Xeon Phi coprocessors.  We will start with some simple example code.

  • Intel Performance Counter Monitor V2.3 released (supporting MacOS and FreeBSD)

    We are proud to announce that Intel Performance Counter Monitor V2.3 (Intel PCM) has been released with the following changes:

    • Support of Apple Mac OS X 10.7 ("Lion") and OS X 10.8 ("Mountain Lion")
    • Support of FreeBSD
    • new tool for monitoring memory traffic per channel on Intel Xeon processor E5 product family.

    With that Intel PCM now supports Linux, Windows (XP, 7, 8 Desktop Mode), FreeBSD and MacOS.
