Do you have questions that you are not finding the answers for in our documentation? Need more training, source code examples, on what specifically? Help us understand what's missing so that we can make sure we develop documentation you care about (what is important, and what is nice to have)! Thank you
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.

We did a webinar this morning at 8am Pacific time on changes and new updates in Cilk in the Intel Parallel Composer beta. I am posting the slides here. Let me know if there's any interest to do another webinar on this around 5pm or so Pacific time - I want to see if there's anyone that couldn't attend due to the time that would have liked to attend. Thanks everyone, and I really enjoyed the questions in today's session.
I want to learn C # programming language where you Start
In my program, I am not set restriction of OpenMP thread number, but I found it only using 4 OpenMP threads on my machine. Why?
My CPU configuration is (reported by Intel VTune ):
Name: Intel(R) Core(TM) Processor 2xxx Series
Frequency: 2.2 GHz
Logical CPU Count: 8
OS is windows 10.
Following is console output by pardiso and openmp while setting KMP_SETTINGS=1 and pardiso message level parameter to 1:
I'm trying to run a code using cilkplus. The idea is to initiallize an array in parallel, using cilk_for, and then read it, in parallel again, to compute some results. However, I have race conditions between instruction on the two consecutive cilk_for. Above you can find an example code that reproduces that error:
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
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
Hello all ,
