Intel VTune Profiler, called Intel VTune Amplifier, is an application performance evaluation and analysis tool working in Microsoft Windows or Linux systems. Its features mainly run for Intel and AMD hardware and some are only for Intel-made CPUs or GPUs. There are six main analysis features: Algorithm Optimization, Microarchitecture and Memory Bottlenecks, Accelerators and XPUs, Parallelism, Platform and I/O, and Multi-Node. One can download it for free on [[the Intel® VTune™ Profiler website]](https://www.intel.com/content/www/us/en/developer/tools/oneapi/vtune-profiler.html#gs.k2twbg) as a stand-alone version or as part of the Intel® oneAPI Base Toolkit. However, parts of advanced analysis in some features are paid services.

The Intel Vtune Profiler includes a tool to conduct Microarchitecture Exploration analysis using events collected in the top-down characterization and allows user to pinpoint hardware issues in an application. The Microarchitecture Exploration records other metrics important to performance and are displayed in the Microarchitecture Exploration viewpoint. Using the hotspot analysis from the algorithm optimization section we are able to identify areas in which our code is taking a lot of CPU time to run. This then allows us to pinpoint an area to utilize the ME analysis tool to determine the level of efficiency of the code running through the core pipeline. The ME analysis instructs the Vtune Profiler to collect a list of events for analysis and determines metrics which allow easier identification of performance issues at the hardware level.
