Recently we posted the “Windows* 8 Tutorial: Writing a Multithreaded Application for the Windows Store* using Intel® Threading Building Blocks”. There we stated that the parallel calculation engine can be ported easily to other mobile or desktop platforms. Android is a good example of such a mobile platform.

Overview
The embedded OS we will be focused on is Yocto Project* version 1.2. This platform supports many Intel BSP’s (board support packages) and as well as a software-based emulator. Here are the steps we will take to run our collection:
Intel® System Studio - Multicore Programming with Intel® Cilk™ Plus
Intel System Studio not only provides a variety of signal processing primitives via Intel® Integrated Performance Primitives (Intel® IPP), and Intel® Math Kernel Library (Intel® MKL), but also allows developing high-performance low-latency custom code (Intel C++ Compiler with Intel Cilk Plus). Since Intel Cilk Plus is built into the compiler, it can be used where it demands an efficient threading runtime in order to extract parallelism. Therefore it's possible to effectively introduce multicore parallelism even without introducing it into each of the important algorithms e.g., by employing a parallel pattern called pipeline. For custom code (e.g., code that's not reused via a library), one can rely (in addition to auto-vectorization) on an extended Array Notation incl. elemental functions (kernels) to explicitly vectorize at a higher level compared to ISA-specific intrinsic functions.
Troubleshooting VTune(TM) Amplifier XE's Power Analysis
We have recently learned about various problems users are experiencing when attempting to use the power analysis capability of the VTune™ Amplifier XE 2013. For example, you may see one of the following messages:
- Error: Power Analysis is not supported on this platform.
- Unknown symbol "cpufreq_freq_attr_scaling_available_freqs" in /var/log after building and attempting to load the power driver module
Below are some suggestions for troubleshooting problems with the power analysis feature.
Intel® Advisor XE Helps You Understand Parallel Efficiency
Today, tuning software isn’t just about making an application run faster, it is also about making sure it is running efficiently.
Desarrollo de aplicaciones de bajo consumo para dispositivos Ultrabook™
El rendimiento de bajo consumo es un componente clave en los dispositivos Ultrabook™ y en los dispositivos móviles en general. Mientras que la nueva generación de dispositivos Ultrabook™ vienen con funciones de hardware incorporadas que mejoran el rendimiento, el consumo de energía no pertenece al dominio del hardware solamente. El software cumple una función importante para que los dispositivos UltrabookTM hagan un uso de energía lo más eficiente posible. En esta sección, encontrará recursos que le ayudarán a diseñar y desarrollar un software "ecológico".
