Intel® VTune™ Profiler

Find and Fix Performance Bottlenecks Quickly and Realize All the Value of Your Hardware

What's New in 2022

Expanded Accelerator Profiling
  • Identify occupancy issues that prevent  GPU code from efficiently using available execution unit (EU) threads by using the GPU Compute/Media hot spots analysis.
  • Analyze data transfer to pinpoint inefficient code paths between host and device in the GPU Offload Analysis.
  • Profile DirectX applications on the CPU host to determine the gaps between the API calls and the reasons causing such inefficiencies.
Hardware Support
  • Get support for the 3rd generation Intel® Xeon® Scalable processors (formerly code named Ice Lake server) and 12th generation Intel® Core™ processor family (formerly code named Alder Lake)
New Profiles
  • Visualize hot code paths and identify time spent in each function and its callees using the Flame Graph in Hot Spots analysis.
  • Diagnose the issues that may cause your system to be overheated or consume significant power using the CPU Throttling analysis.
Better Workflow
  • Gain insight into system configuration, performance, and behavior with Platform Profiler—now fully integrated into Intel VTune Profiler.
  • Quickly analyze the application performance characterization with pointers to deeper analysis using Performance Snapshot.
Better Data
  • Expanded I/O Analysis: Quickly visualize I/O hardware use with a platform diagram. Discover the root cause of low throughput in Intel Data Direct I/O Technology. Optimize latency using extended utilization metrics in I/O analysis. Get added support for MPI applications.
  • Application Performance Snapshot: Analyze workloads at scale to identify outliers and where they occurred. Get PCIe bandwidth information in command-line reports.
