Modern Processor Performance Analysis

Performance on modern processors requires much more than optimizing single thread performance. High-performing code must be:

  • Threaded and scalable to utilize multiple CPUs
  • Vectorized for efficient use of multiple FPUs
  • Tuned to take advantage of non-uniform memory architectures and caches

With Intel® VTune™ Amplifier, you get all these advanced profiling capabilities with a single, friendly analysis interface. And for media applications, you also get powerful tools to tune OpenCL™ applications and the GPU.

“Hotspot” analysis identifies where your application is spending a lot of time. Tuning these hotspots will have the biggest impact on overall performance. It also details threading performance, showing the common causes of poor performance such as imbalance and lock contention.

Powerful Analysis Lets You Create Faster Code

Whether you’re tuning for the first time or doing advanced performance optimization, Intel VTune Amplifier provides accurate profiling data―collected with very low overhead. But good data isn’t enough. Intel VTune Amplifier gives you the tools to mine it and interpret it. Quickly turn raw profiling data into performance insight using the graphical interface to sort, filter, and visualize data from a local or remote target. Or use the command line interface to automate analysis.

What’s New For 2018

  • Easier tuning of threaded message passing interface (MPI) applications. High-performance computing (HPC) analysis adds enhanced metrics for MPI including MPI imbalance and performance of critical path rank. Application Performance Snapshot merges MPI and application data, includes richer metrics, and adds MPICH compatibility.
  • Optimize private cloud-based applications. Profile inside Docker*, LXC*, and Mesos* containers and attach to running Java* services and daemons.
  • Enhanced Python* profiling. Locks and Waits analysis tunes threaded performance of mixed Python and native code. Preview: Memory consumption analysis for Python, C, and C++.
  • Easier threading optimization of applications using Intel® Threading Building Blocks (Intel® TBB). Advanced threading analysis extends classification of high overhead and spin time.
  • Easier analysis of remote Linux* systems. Automated install of performance collectors on a remote Linux target.
  • Tune GPU kernel algorithms. Analyze GPU kernel execution to find memory latency or inefficient kernel algorithms. See the hotspot on the OpenCL software source and assembly.
  • Cross-operating analysis for all supported operating systems. Collect data on Linux (or any supported operating system) and analyze it in the user interface on Microsoft Windows*, Linux, or macOS*. Download only what you need. Your license enables use on all operating systems.
  • Support for the latest processors including Intel® Xeon®, Intel® Xeon Phi™, Intel® Core™ and Intel Atom® processors.
