Support & Community
Whether you're tuning for the first time or doing advanced performance optimization, Intel VTune Amplifier provides a rich set of performance insight into CPU & GPU performance, threading performance, scalability, bandwidth, caching and more. Analysis is faster and easier because VTune Amplifier understands common threading models and presents information at a higher level that is easier to interpret.
Example of VTune User-Interface
Claire Cates, Principal Developer of SAS Institute said, "Last week, Intel VTune Amplifier XE helped us find almost 3X performance improvement. This week it helped us improve the performance another 3X".
Intel VTune Amplifier has built-in understanding of parallel programming models including Intel® Threading Building Blocks, OpenMP* 4.0 and Intel® Cilk™ Plus. This makes it easy to see and understand multi-threading concepts such as task begin/end, synchronization, and wait time Lock & waits analysis. Visualization over time lets you easily see lock contention, load imbalance and inadvertent serialization, which are all common causes of poor parallel performance. VTune is available as a standalone tool or as part of all Parallel Studio Editions for Windows, which integrate into Visual Studio.
Features & Benefits
- Hotspots analysis gives you a sorted list of the functions over all call stacks consuming CPU time. Fixing these gives you the biggest benefit. Clicking the VTune bar-chart output takes you straight to the source code, keeping you productive.
- VTune provides profiles of basic hotspots and locks-and-waits for software as it runs on Intel Architecture and compatible processors. Waiting too long for a lock causes processing cores to be under-used as they wait for work. This is a common cause of poor performance in parallel programs. VTune Amplifier provides a productive remedy to this parallelism condition.
- Support directly from Intel to you. Every paid version of our software products automatically gives you access to Intel Premier Support for updates, direct and private interaction with the engineering team, and community forums to exchange ideas, solutions and more.
