Intel® VTune™ Profiler
Overview
This document explains how you use Intel VTune Profiler to profile serial and multithreaded applications on CPU, GPU, and FPGA platforms. You can run Intel VTune Profiler to profile software applications (local or remote collections) on Windows* and Linux* platforms. Analyze your choice of algorithm and locate or determine:
The most time-consuming (hot) functions in your application and/or on the whole system
Sections of code that do not effectively utilize available processor time
The best sections of code to optimize for sequential performance and for threaded performance
Synchronization objects that affect the application performance
Whether, where, and why your application spends time on input/output operations
Whether your application is CPU or GPU bound and how effectively it offloads code to the GPU
The performance impact of different synchronization methods, different numbers of threads, or different algorithms
Thread activity and transitions
Hardware-related issues in your code such as data sharing, cache misses, branch misprediction, and others
