How to use Intel Cilk Plus extension, to speed up your Android application with threading features

Intel Cilk Plus is an important language extension of Intel Compiler, to help you implement multiple-threading easily and fast, to improve your application's performance on multi-core systems. While more and more cores on Android devices, it is also more important to efficiently use the multi-core features.

    Submissions open: High Performance Parallelism Gems

    We have all had our little discoveries and triumphs in identifying new and innovative approaches that increased the performance of our applications. Occasionally we find something more, something that could also help others, an innovative gem. You now have an opportunity to broadcast your successes more widely to the benefit of our community. You are invited to submit a proposal to a contribution-based book, working title, “High Performance Parallelism Gems – Successful Approaches for Multicore and Many-core Programming” that will focus on practical techniques for Intel® Xeon® processor and Intel® Xeon Phi™ coprocessor parallel computing. Submissions are due by May 29, 2014.

  • How to Start VTune Amplifier from Ubuntu Launcher

    Under Linux many commands are executed from the command line, which is OK. But if the program you are starting has a mouse driven GUI in my view the command line doesn't really make sense.

    NOTE: In all the following <install dir> means where you installed Intel® System Studio. On my system this is /opt/intel/system_studio_2014.0.025. Use the location you chose during installation.

    VTune Amplifier is for me such a case. To start it from the command line you need to

  • Diagnostic 15042: pragma supersedes previous setting

    Cause:

    This diagnostics message comes when the parameters of the directive are contradictory.  

    In the example below, the directive !dir$ loop count has two clauses, avg() and max(). Notice the contradiction in these two clauses: the max() parameter is lesser than the avg() clause value:

  • The Chronicles of Phi - part 5 - Plesiochronous phasing barrier – tiled_HT3

    For the next optimization, I knew what I wanted to do; I just didn’t know what to call it. In looking for words that describes loosely-synchronous, I came across plesiochronous:

    In telecommunications, a plesiochronous system is one where different parts of the system are almost, but not quite, perfectly synchronized.
