Registering for Webinar on Advanced Vectorization and Optimization

The webinar will cover some of the loop patterns which posed challenge for vectorization and how Intel Compiler vectorizes those loop patterns with the latest 16.0 compiler. Topics covered in the webinar include:

  1. Compress/Expand Loop Pattern
  2. Histogram loops
  3. Search Loop Pattern
  4. Vectorization of STL Vectors
  5. Valarrays
  6. OpenMP4.0 SIMD constructs support

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.

    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?

    Using global pointers to allocate memory on the MIC and reusing it

    Hi all,

    I am using the offload programming model for my project. What I have is a global pointer that I use to allocate memory on the MIC. After doing some more computation on the host I then try to copy the results from host memory to the memory in the MIC using in() for host structure and nocopy() for the global pointer. The documentation and a few of the forum posts say that it should work however in my case it results in a segfault.

    What I read:
