In my previous blogs I discussed the most common pitfalls in application power consumption and how to use the Battery Life Analyzer (BLA) software to find power issues. In this blog I will explain how to use the Microsoft* Windows Performance Toolkit (WPT) to determine what causes power issues.
What is WPT?
WPT includes two tools: the Windows Performance Recorder (WPR) which collects data, and the Windows Performance Analyzer (WPA) which analyzes data.
In my blog about the most common pitfalls in analyzing application power consumption (most common pitfalls) I talked about potential issues that could drive power consumption to higher amounts. C-states are states when the CPU has reduced or turned off selected functions. Different processors support different numbers of C-states in which various parts of the CPU are turned off. To better understand the C-states that are supported and exposed, contact the CPU vendor.
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.
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.
Notebook/Laptop PC is a rapidly growing segment, which is bringing anywhere, anytime computing and connecting capability to the users. To improve the mobile computing experience, take advantage of one and more of these features:
