    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.

    IVB Atmospheric Light Scattering

    1. Introduction

    Atmospheric light scattering is an important natural phenomenon, which arises when light interacts with the particles distributed in the media. Rendering such effects can be exploited by many applications, such as computer games, to greatly improve scene realism. To accurately compute scattering contribution, a complex nested integral has to be solved for each screen pixel. Due to the complexity of the computations involved, achieving natural-looking atmospheric scattering effects at interactive frame rates is a challenging problem.

  • 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.
