Command line interface amplxe-cl and GUI interface amplxe-gui were re-named to vtune and vtune-gui respectively
Intel® VTune™ Profiler has been updated to include more recent versions of 3rd party components, which include functional and security updates. Users should update to the latest version.
GPU accelerators support:
New GPU Offload analysis added to explore and correlate code execution across CPUs and GPUs. You can identify a kernel of interest for GPU-bound applications and explore further with GPU Compute/Media Hotspots analysis.
GPU Compute/Media Hotspots analysis updated with GPU in-kernel analysis for OpenCL™ code and an option to filter by a kernel of interest.
Command line hotspots report now supports GPU analysis types. You can apply the computing-task and computing-instance groupings to your collected data to focus on time-intensive computing tasks.
Dynamic instruction count collection (available as part of the GPU Compute/Media Hotspots Analysis) improved to provide better accuracy for basic block Assembly analysis.
Support for Intel® Processor Graphics Gen11.
Platform analysis support:
System Overview analysis updated to serve as an entry point to platform analysis. Use this analysis to assess system (IO, accelerators and CPU) performance and review guidance for next steps.
New Hardware Tracing mode in the System Overview analysis enables application analysis on the micro-second level and identification of causes for latency issues.
HPC analysis improvements:
Max and Bound Bandwidth metrics added to Application Performance Snapshot to better estimate the efficiency of the DRAM, MCDRAM, Persistent Memory and Intel® Omni-Path usage.
Platform Profiler new features and improvements:
Overview and Memory views extended with new metrics to analyze Non-Uniform Memory Access (NUMA) behavior.
User authentication and authorization implemented to enable access control to user data.
Added a new option for users to choose or modify the location of Platform Profiler data files.
Energy analysis improvements:
New Throttling analysis added to identify causes for system throttling, including violation of safe thermal or power limits.
Options for Energy analysis, based on the Intel SoC Watch data collector, extended to monitor processor package energy consumption over time and identify how it correlates with CPU throttling.
Cloud and containerization support:
Containerization support extended with an option to install and run VTune™ Profiler in a Docker* container and profile targets inside and outside the same container.
Added support to profile applications running in Amazon Web Services* (AWS) EC2 Instances based on Intel microarchitecture code name Cascade Lake X.
New Fabric Profiler performance tool added to VTune™ Profiler in Preview mode. Use Fabric Profiler to identify detailed characteristics of the runtime behavior for an OpenSHMEM application.
Quality and usability improvements:
Symbol resolution for effective source-level analysis enabled for crossgen (Ahead-of-JIT compilation) functions on Linux* systems.
Interactive Help Tour (available on the Welcome page) guides you through the product interface using a sample project.
