Recientemente publicamos la “Guía instructiva para Windows* 8: cómo escribir una aplicación multiproceso para Windows Store* con Threading Building Blocks de Intel®”. En esa guía dijimos que el motor de cálculo paralelo se puede portar fácilmente a otras plataformas móviles o de escritorio. Android es un buen ejemplo de ese tipo de plataforma móvil.
Big Data requires processing huge amounts of data. Intel Advanced Vector Extensions 2 (aka AVX2) promoted most Intel AVX 128-bits integer SIMD instruction sets to 256-bits. Intel AVX brought 256-bits floating-point SIMD instructions, but it didn't include 256-bits integer SIMD instructions. Intel AVX2 allows you to operate with the AVX 256-bits wide YMM register for integer data types. In this post, I’ll explain how developers can speedup big data processing with the new 256-bits integer SIMD instructions.
Power management policy has evolved over the years. The earliest policies consisted of little more than some critical temperature sensors and an interrupt routine that attempted (often unsuccessfully) to cleanly shut down the system before something really bad happened.
Unlike a lot of previous recent blogs, this series is about power management in general. At the very end of the series, I’ll write specifically about the Intel® Xeon Phi™ coprocessor.
I have talked incessantly over the years about power states (e.g. P-states and C-states), and how the processor transitions from one state to another. For a list of previous blogs in this series, and well as other related blogs on power and power management, see the article at [List0]. But I have left out an important component of power management, namely the policy.

Thank you for your interest. The Intel® Software Development Tools 2015 Beta program is now closed.
If you’d like to try out the official release of the Intel® Parallel Studio XE 2015, visit our product pages and grab a free 30-day evaluation copy. If you have an existing license for our tools (not Beta), you can download the latest release from the Intel® Registration Center.
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.
Yep. Here is another blog series from yours truly. Unfortunately, it will delay my long awaited – at least by me – discussion on measuring power.
Here is a rough outline for the blogs:
近来，我们发布了 “Windows* 8 教程：使用英特尔® 线程构建模块为 Windows Store* 编写多线程应用”。其中我们提到，并行计算引擎很容易导入其他移动或台式机平台。Android 是这种移动平台的一个典型的例子。
