FAQS: Compilers, Libraries, Performance, Profiling and Optimization.

In the period prior to the launch of Intel® Xeon Phi™ coprocessor, Intel collected questions from developers who had been involved in pilot testing. This document contains some of the most common questions asked. Additional information and Best-Known-Methods for the Intel Xeon Phi coprocessor can be found here.

Баги и фичи

Уважаемые читатели и авторы русскоязычных блогов Сообщества Разработчиков Intel, с сентября 2012 года блоги работают на новой площадке - Intel Developer Zone (IDZ), используют новый "движок", дают новые возможности, и, к сожалению,.... новые баги. Так, в течение нескольких недель вместо русскоязычных блогов на соответствующей странице IDZ отображались блоги на английском языке, а RSS-подписчикам однажды даже довелось получить посты на китайском языке. Существуют проблемы и с отображением блогов и с их созданием. Хотя их число постепенно и неуклонно уменьшается, но пока оно больше нуля.

setup MIC to MIC passwordless ssh


Is it possible to setup MIC to MIC passwordless ssh?

When I ssh from one MIC to another:

root@mic0 ~]# ssh mic1
The authenticity of host 'mic1 (' can't be established.
ECDSA key fingerprint is -------------------------------------------------------
Are you sure you want to continue connecting (yes/no)? ^C
[root@mic0 ~]# 

What are the exact requirements for setup?

Caffe* Scoring Optimization Intel® Xeon® Processor E5 Series

    In continued efforts to optimize Deep Learning workloads on Intel® architecture, our engineers explore various paths leading to the maximum performance.  Not long ago, a technical preview of optimized AlexNet training on Caffe was published. Now we are sharing another preview of our work completely focused on the classification path and bringing it to new performance levels never demonstrated before on an Intel CPU.

  • ofed-driver compilation error, centos 6.7

    I am using Centos 6.7, kernel 2.6.32-573.3.1.el6.x86_64, OFED 3.18-1. From the release information I see that mpss 3.6 is supported on RH6.7, but I do not see the corresponding ofed-driver package in mpss-3.6/ofed/modules. I tried to build it myself, but I ran into the following error trying to rpmbuild ofed-driver in mpss-3.6/src

    OpenCL module fail in Opencv3.0 (CentOS 7) official program (Ok in Windows)

    Hi, there, I tried to use OpenCL module in OpenCV3.0, This is official program(under project sample-cpp-(EXAMPLE)facedetect)  and could run successfully on Windows 7 (VS2012),
    It's Ok when
    However, when ocl::setUseOpenCL(true); or comment it out, error occurred:

    Compiling LTTng for the Xeon Phi


    I am currently in trying to compile LTTng for the Xeon Phi for the first time, I started by trying to compile Userspace-RCU which should support the Xeon Phi, as x86_64-linux-k1om is recognized. I am using GCC provided in the MPSS release, as I do not need vectorisation for it. I am using a CentOs 6.6 computer with mpss 3.4.2 installed on it. Intel Parallel studio 2015 is also installed.

    I am currently trying :

    CC=/opt/mpss/3.4.2/sysroots/x86_64-mpsssdk-linux/usr/bin/k1om-mpss-linux/k1om-mpss-linux-gcc ./configure --host=x86_64-k1om-linux
