Intel® VTune™ Profiler
Quickly Find and Fix Performance Bottlenecks and Realize All the Value of Your Hardware
Performance Analysis for Applications & Systems
Intel® VTune™ Profiler optimizes application performance, system performance, and system configuration for HPC, cloud, IoT, media, storage, and more.
- CPU, GPU, and FPGA: Tune the entire application’s performance―not just the accelerated portion.
- Multilingual: Profile Data Parallel C++ (DPC++), C, C++, C#, Fortran*, OpenCL™, Python*, Google Go* programming language, Java*, Assembly, or any combination.
- System or Application: Get coarse-grained system data for an extended period or detailed results mapped to source code.
- Power: Optimize performance while avoiding power- and thermal-related throttling.

Features
Get the Big Picture and the Critical Details
With today’s variety of computer architectures, a performance profiler must be able to diagnose many kinds of bottlenecks. Intel VTune Profiler includes:
- System and Application Overview Profiles: These identify where to focus tuning or how to configure systems. They collect less data and can run for a longer time.
- Application Performance Snapshot is designed for clusters with thousands of ranks.
- Platform Profiler is well suited to cloud servers.
- Performance Snapshot examines individual applications.
- Focused Profiles: These take a more detailed look at different classes of bottlenecks such as compute, memory, threading, accelerator offload, throttling, or I/O. Precise profiling information is annotated onto the code source.
Turn Raw Data into Answers
Performance optimization is a bit like solving a mystery. You gather the evidence, analyze it, and make sense of what’s really going on. Summaries, tips, filtering, and annotations make you more productive.
- Source View: See the profiling results on your source
- Timeline Filtering: Focus on bottlenecks as they change with time
- Summary Reports: Get the big picture and tips for further analysis
Now Available as a Server
Intel VTune Profiler can be installed as an application or a server. A server installation lets a small group of users:
- Access with a web browser
- Share results with other users who have server access
- Profile any target by preinstalling the collector agent or pushing from the server via SSH
What's New in 2021?
Accelerator Profiling
- Offload cost profiling identifies unnecessary data transfers. Explore GPU offload analysis.
- GPU analysis adds DPC++ and multi-GPU support, SIMD metrics, OpenMP* offload pragma awareness, a new memory diagram, and a simplified driver.
- Application Performance Snapshot adds GPU analysis.
- FPGA analysis adds DPC++ support, stall and data transfer by compute unit, and a simplified workflow.
- Intel® Iris® Xe MAX graphics support helps you deliver applications optimized for Intel's first discrete GPU.
New Profiles
- Processor Trace finds short performance anomalies like page faults, system calls, or thread switches.
- CPU, GPU, and FPGA active power analysis debugs throttling, optimizes for a power budget, and tunes flops per watt.
Better Workflow
- Intel® VTune™ Profiler server improves security and is easier to deploy with preinstalled collection agents.
- Platform Profiler gains a simplified setup and remote workflow.
- Open-source communication agent simplifies adding performance analysis to real-time operating systems.
