Is your software sluggish? Are you not seeing the performance scaling you expected on multicore processors? Intel® VTuneTM Amplifier XE is 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. The powerful performance profiling tool removes the guesswork and analyzes performance behavior in Windows*and Linux* applications, providing quick access to scaling information for faster and improved decision making. Use Intel VTune Amplifier XE to fine-tune for optimal performance, ensuring cores are fully exploited and new processor capabilities are supported to the fullest. For advanced performance optimization and greater value, the Intel VTune Amplifier XE performance profiling tool is also available as part of the Intel® Parallel Studio XE, Intel® C++ Studio XE, Intel® Fortran Studio XE and Intel® Cluster Studio XE product suites. |

Intel VTune Amplifier XE Overview This is an overview of a few of the major features in the Intel VTune Amplifier XE performance profiling tool. This is a great first video to watch before using an evaluation copy of Intel VTune Amplifier XE. |
|
Intel VTune Amplifier XE Frames This video highlights the use of frame analysis in Intel VTune Amplifier XE to filter performance profiling results to get to actionable information. Frame analysis was inspired by the needs of video applications like games that must meet a latency target for each video frame. It has been implemented in a general manner so it can be useful in other applications such as a simulator time loop. |
|
|
| Intel VTune Amplifier XE Setup Standalone This video shows how to setup and profile your application in the Intel VTune Amplifier XE performance profiling tool. It demonstrates the standalone user interface available on both Linux* and Windows*. Microsoft Visual Studio* integration is available on Windows. This is a great video to watch before your run your first profile using Intel VTune Amplifier XE. |
|
Using the Timeline in Intel VTune Amplifier XE This 10-minute video shows the features of the timeline in Intel VTune Amplifier XE, and gives examples of how to use it to understand your application's performance.

"Intel® VTune™ Amplifier XE's hotspot analysis ran an order of magnitude faster [than VTune 9]! It gives me everything I want and none of the instrumentation issues. It seems to be a major reimplementation of the profiling tools, not just a new UI on the same tools. I'd strongly recommend Intel VTune Amplifier XE to anyone wanting to understand better where their time is going in scientific calculations. Tuning without it feels like compiling without warning or error messages!" |
