  • Using Intel® VTune™ Amplifier XE to Tune Software on the Intel® Xeon® Processor E5 Family

    Download this guide to learn how to identify performance issues on software running on the Intel® Xeon® Processor E5 family
    (based on Intel® Microarchitecture Codename Sandy Bridge-EP/EX/EN). The guide explains how to use Intel® VTune™ Amplifier XE's General Exploration profile for Xeon processor E5 servers.  It explains how to identify the most common software performance issues and gives suggestions for how to address each.

  • Ultrabook Part 2: Intel® VTune™ Amplifier XE 2011 with Windows 8* and Visual Studio* 2012 RC

    As I continue to explore different Ultrabook capabilities, in this blog I decided to look into a powerful threading and performance optimization tool for C/C++, .NET, and FORTRAN developers who need to understand an application's serial and parallel behavior to improve performance and scalability: Intel® VTune™ Amplifier XE 2011.

    Introducing Intel Ultrabook™ – Part One

    In all my years in college I have used a laptop PC. Recently, I’ve been tempted to get a MacBook Air Pro because of its light-weight and stylish look. But, since starting at Intel, I’ve been able to explore and play with an Ultrabook and it has changed my mind completely. The reason is simple: Ivy Bridge Ultrabooks are just amazing! Ultrabooks will be even more amazing when you add the touch screen capability of Window 8 later this year.

    Optimizing XuanYuan with Intel® Graphics Performance Analyzer on Intel® HD Graphics

    Engineers from Intel & Tencent used Intel® GPA to improve the performance of XuanYuan by 1.34x. The performance gains from these optimizations also improved the frame rate on a pre-release Ivy Bridge system by 1.30x from 66 fps to 86 fps.

  • Редактирование Onloaded Shadows: перенос обработки теневых карт с графического на центральный процессор (Статья)

    Во многих приложениях источник света передвигается очень медленно. Это означает, что обновление тени может происходить не каждый фрейм. С помощью метода Onloaded Shadows можно перенести асинхронную обработку теневых карт на CPU.

  • Accessing Intel® Power Gadget from Intel® Energy Checker SDK

    Intel® Power Gadget 2.0 can be associated with the Intel® Energy Checker SDK (Intel EC SDK). Used as an ESRV* DAQ module**, the Intel® Power Gadget can provide processor average power (Watt), cumulative energy consumed (Joule) and instantaneous frequency (MHz) as counters. These counter’s values can then be read by any application using the SDK API or monitored with SDK tools.

    История развития форматов видеосжатия

    Далёкий 1988й год был полон удивительных событий. В этом году увидел свет 4й альбом группы Metallica «...And justice for all», а СССР запустил в свой первый и единственный полёт многоразовый космический корабль «Буран».
