Event based sampling uses counters on the Intel processors to detect what your software is doing. This is helpful for tuning and improving software performance. Typical hotspot analysis shows you where your software spends most of the execution time, but event based sampling allows you to see not just what sections of your application take the most time but why and what it is doing.
I hope you are all enjoying the new Intel® Core™i7 platforms. Most people are very pleased with the performance of these new platforms. I hope all of you software developers are regular VTune Analyzers users too (but I know not all of you are). One of the great advantages of VTune Analyzer’s event based sampling feature is that it doesn’t just show you where your code spends the most cpu time, it helps you understand why. When you understand why you can better make changes that will improve performance. Dr.
Today is the second anniversary of the Sun and Intel joint agreement to optimize the Solaris operating system for Intel Xeon processors. Like last year, when I wrote this summary of our work, I decided to recap where we are to date.
Like last year’s edition, this is pretty much off the top of my head.
