VTune Amplifier XE for 2nd Generation Intel® Core™ processor

New performance analysis features for Intel® microarchitecture code name Sandy Bridge!

Are you using one of the new 2nd Generation Intel® Core™ processors? If so, you should know about all the new features just added to the Intel® VTune™ Amplifier XE Performance Analyzer! VTune Amplifier XE supports several levels of performance tuning for Intel processors. For hardware and microarchitectural tuning, VTune Amplifier XE allows users to sample the occurence of various events on the platform (such as cache misses, branch mispredicts, stalls, etc) and track them to the executing function, process, and thread that caused them. At the software/algorithmic level, VTune Amplifier XE allows developers to find which functions take the most time to execute, determine an application's concurrency, and locate potential threading issues.

And beginning with update 2, just launched this month, Intel VTune Amplifier XE has the following new features specifically to support the Intel® microarchitecture code name Sandy Bridge:

  • Pre-defined event profiles let you collect all the events necessary for diagnosing certain issues
  • Built-in metrics use event values and system information to compute useful quantities such as % processor cycles spent on memory access, DTLB miss overhead, and Mispredicted branch cost
  • Automatic highlighting of values over a "normal" threshold for a particular metric helps you focus on potential issues
  • Tooltips and detailed documentation help you understand the metrics and events and what they are measuring
These new features are the result of our efforts to continually improve VTune Amplifier XE and make it as user-friendly as we can. The pre-defined profiles, metrics computations, and automatic highlighting are designed to help novice performance tuners to begin making insights into their platform's performance right away. You can evaluate VTune Amplifier XE for free here. VTune Amplifier XE works on most recent Intel processors, although many of the features mentioned above are just for Intel processors codenamed Sandy Bridge.

Over the next several months we will be releasing even more helpful documentation and guidance on performance analysis of processors codenamed Sandy Bridge. Up next is the 2nd Generation Intel® Core™ processor Optimization Guide, with details on some of the most common performance issues, how to find them, and suggestions for improvement.
