  • How to change mac address of each mic device?

    I'm using MPSS 3.4.3 on windows.
    I challenged to change  mac address of each mic device by modification of "micN.xml".
    But, it failed.

    I tried following step.
    1, Modify mac address term of "micN.xml".
    2, micctrl -r
    3, micctrl --start
    ( I also tried PC reboot. )

    How to change mac address of each mic device?


    DH77 motherboard

    I am attempting to get KNC (7120) working in a Win7 x64 system that is based on a DH77KC motherboard.

    System boots and I can get into Windows, but the card is not usable, because it is listed in the device manager with a status: "This device cannot find enough free resources that it can use. (Code 12)"

    It is the only card physically plugged into the motherboard (I'm using integrated video). I've disabled most nontrivial devices through BIOS, up to & including front panel USB, with no effect.

    视频 - 借助英特尔至强融核协处理器实现并行编程

    Colfax International 最近发布了下列一组关于英特尔(R) 至强融核(TM) 协处理器的视频。

    该视频主要介绍了开发面向英特尔至强融核协处理器的应用时所需要并推荐采用的软件工具。 我们首先介绍启动协处理器以及运行预编译的可执行文件所需的软件。

    我的应用是否能受益于 MIC 架构
    在本视频中,我们将探讨可在英特尔至强融核协处理器上有效运行的应用类型。 我希望上述介绍能够帮助大家回答“我的应用是否能受益于 MIC 架构?”

    OpenMP spinning time


    I am using a simple Merge Sort benchmark on the Xeon Phi. 78% of the total CPU time is consumed by ""

    I tried to reduce the watsed time by the OpenMP runtime library by setting the "export KMP_BLOCKTIME=0". Please note that the application is running natively on the MIC. I have also tried "export OMP_WAIT_POLICY=passive". No effect!

    Why this does not have any effect on the execution time or the wasted CPU time?

    Thank you.

    Run a function on mic0 and mic1 concurrently (OpenMP)


    I am implementing openMP offload program currently running on single Phi device.
    My computing node has 2 Phi devices named mic0 and mic1.
    Could you please let me know how I can extend the following code section to run on both devices simultaneously.

    Assume the code sections can be run independently to each other where all data (input and output) are independent.
    I need to know the structure of code and the directives to do it properly in openMP. Further, compilation method also required.
