BKMs on the use of the SIMD directive

We had an ask from one of the various “Birds of a Feather” meetings Intel® holds at venues such as at the Super Computing* (SC) and International Super Computing* (ISC) conferences. The customer wanted to know BKMs (Best Known Methods) on the proper usage of the new OpenMP* 4.0 / Intel® Cilk™ Plus SIMD directive. I volunteered to create such a list. Investigating the topic more thoroughly, I discovered that there is already a vast amount of resources on vectorization and the use of the SIMD directive.

Error Message: "adb - device not found" in Intel® VTune™ Amplifier 2014 for Systems

When trying to Create a New Analysis in Intel® VTune™ Amplifier 2014 for Systems to connect to an Android* Device.

You may get the error message:

adb - device not found

cannot communicate with the target.

Error while getting collector context values.

or in Project Properties you might get the error message:

There are no Android Devices attached to this machine.  You will not be able to collect any data.

    Dear passionate power management reader,

    Doing an internet scan for material having to do with power management policy, my next blog series, I ran across a blog that I believe to be excellent. As many of you have discovered, I generally write at a pretty high level, though technical. I do this intentionally. At the beginning of my blogging career, there was not much written about power management that was comprehensible to a competent engineer who was not a power expert.

    Using Intel® VTune™ Amplifier 2014 for Systems on non-rooted Android* devices

    For the first time Intel® VTune™ Amplifier 2014 for Systems brings the most important, core capability of determining the hotspot in the C/C++ portion of your application to most Android* devices on Intel® processors (including rooted, not-rooted devices and with or without version compatible device drivers), such as those available at http://software.intel.com/en-us/android/get-device.  This article will concentrate on the options required to make this work on non-rooted devices.

  • Upgrade Your Fortran Compiler

    Still using an old version of Intel® Fortran Compiler or Intel® MKL?
    You're probably leaving performance on the table.

     

    You have an opportunity to increase your application's performance by taking advantage of the dramatic evolution of processors with increasing core counts and wider vector widths. Older versions of Intel® Fortran and Intel®  Math Kernel Library (Intel® MKL) pre-date most of this. Only the new versions of Intel's compilers and libraries provide built-in support for these performance innovations.
