Performance Monitoring on User-defined ROI

by Sertac Olgunsoylu for CERN SFT

This is a project to extend Linux perf tool to collect and organize performance data for user-defined regions of the code. Currently, perf collects data for the whole workload. This is not useful if only a subset of large code is of interest. The project is to enhance perf tool by enabling collecting performance data for the relevant regions of the code and organizing data accordingly.
