Intel C++ Compiler 16.0 is now available in Intel Parallel Studio XE 2016

The new version Intel C++ Compiler 16.0 is now available in Intel Parallel Studio XE 2016 that has launched early this week. If your support license is current you can download and install this at no additional charge from the Intel Registration Center

You will find some blog postings about some new features and new free tools.

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?

    Compiling Issue

    Hi,

    I am compiling Gromacs-5.0.6 with intel compiler but i am getting following error.

    .....................................

    In file included from /usr/local/cuda-7.0/include/crt/host_runtime.h(70),
                     from /opt/intel/composer_xe_2015.3.187/compiler/include/stddef.h(45):

    Diagnostic 15529: xxxx was not vectorized: volatile assignment was not vectorized. Try using non-volatile assignment.

    Diagnostic message: xxxx was not vectorized: volatile assignment was not vectorized. Try using non-volatile assignment.

    Cause:

    This diagnostic message is emitted when the loop in question doesn't meet the vectorization criteria in that any code involving volatile assignment within the loop prevents vectorization. In the example below the iteration control variable causes a conditional loop exit preventing vectorization.

  • OpenMP 4.0 implementation in Intel Compiler

    Hi..

     

    CAN YOU PLEASE TELL ME, WHICH INTEL COMPILER VERSION HAS IMPLEMENT OPENMP 4.0 DIRECTIVES ..? 

     

    I am trying to execute openmp 4 (#pragma omp target data  map.. / #pragma omp target) ---> I am using icc (ICC) 15.0.2 20150121 on stampede, but not able to compile. [goal is to compare 1 & 2]

     

    < login2.stampede(197)$ icc -openmp omp_target_cost_offload.c -mmic -o ompTarget_cost_offload

    omp_target_cost_offload.c(44): warning #3180: unrecognized OpenMP #pragma
