VTune

VTune Profiler   (formerly VTune Amplifier) is a performance analysis tool for x86-based machines running Linux or Microsoft Windows operating systems. Many features work on both Intel and AMD hardware, but the advanced hardware-based sampling features require an Intel-manufactured CPU.

VTune is available for free as a stand-alone tool or as part of the Intel oneAPI Base Toolkit.

Features

 * Languages: C, C++, Data Parallel C++ (DPC++), C#, Fortran, Java, Python, Go, OpenCL, assembly and any mix. Other native programming languages that adhere to common standards can also be profiled.
 * Profiles:Profiles include algorithm, microarchitecture, parallelism, I/O, system, thermal throttling, and accelerators (GPU and FPGA).
 * Local, Remote, Server : VTune supports local and remote performance profiling.  It can be run as an application with a graphical interface, as a command line or as a server accessible by multiple users via a web browser.
