Profiling Python* With Intel® VTune™ Amplifier: A Covariance Demonstration


Intel® VTune™ Amplifier is source-code profiling software, popular in the High Performance Computing (HPC) community for its versatile and accurate sampling as well as its low collection overhead. Software stack sampling, thread profiling, and low-level hardware event sampling are all available. Along with command line interface, Intel VTune Amplifier also has a mature and convenient graphical user interface. A user can “mouse-around” and effectively dig through their code and map bottlenecks to specific lines in the source.
