Free webinar April 7 2015 9am PST "Further Vectorization Features of the Intel Compiler"

There is a free webinar “Further Vectorization Features of the Intel Compiler” coming next Tuesday talking specifically about getting more vectorizations from Intel Compilers. But you would benefit it more if you've watched/listened to the previous webinar Performance essentials using OpenMP* 4.0 vectorization with C/C++.

Intel® Xeon Phi™ Coprocessor code named “Knights Landing” - Application Readiness

As part of the application readiness efforts for future Intel® Xeon® processors and Intel® Xeon Phi™ coprocessors (code named Knights Landing), developers are interested in improving two key aspects of their workloads:

  1. Vectorization/code generation
  2. Thread parallelism

This article mainly talks about vectorization/code generation and lists some helpful tools and resources for thread parallelism.

  • Оптимизировали, оптимизировали, да не выоптимизировали!

    Оптимизация? Конечно, каждый сталкивался с данной задачей при разработке своих, сколь-нибудь значительных, требующих определённых вычислений, приложений. При этом способов оптимизировать код существует огромное множество, и, как следствие, различных путей сделать это в автоматическом режиме с помощью опций компилятора. Вот здесь и возникает проблема – как выбрать то, что нужно нам и не запутаться?

    tqli hangs on i7-4790

    Hello,

    i am using the routine tqli from the book Numerical Recipes (www.physics.sdsu.edu/~johnson/phys580/tqli.c) since several years without any problems on different processors and different compilers. I have a new computer with i7-4790K.

    Now this routine hangs somtimes. With same input values sometime it works and sometimes it hangs in an infinite loop.(the while lopp nerver ends)

    The code is compiled with intel c++ compiler v14 but it also happens with the newest v15.

    Compiler error assertion failed at: "shared/cfe/edgcpfe/lower_init.c" on debian jessie

    Hi,

    I installed parallel_studio_xe_2015_update3 on my debian jessie on linux, and when i'm trying to compile the code I'm working on with icpc, there is this strange error :

    /usr/include/c++/4.9/sstream(564): internal error: assertion failed at: "shared/cfe/edgcpfe/lower_init.c", line 5243

    ~basic_stringstream()

    with no links to my code or anything else.

    What did I missed?

    Config:
    kernel version 3.16.0-4-amd64

    libstdc++6

    g++ 4.9.2 also installed (no issues with this compiler)
