Intel® VTune™ Profiler 2020 (formerly “Intel® VTune™ Amplifier) is now available. https://software.intel.com/en-us/vtune
- 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.
- New hardware/operating systems/IDEs support:
- 10th Gen Intel® Core™ processors
- Ubuntu* 19.10
- Microsoft* Windows* 10, November 2019 Update
