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. The supported languages include C, C++, DPC++ (data-parallel C++), C#, Fortran, Java, Python, Go, OpenCL, or compound usage of the above. 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 [[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.
