Tutorials and Samples
Intel® VTune™ Profiler provides web tutorials using sample code for step-by-step instructions on configuring and interpreting performance analysis.
Analyze Common Performance Bottlenecks - C++ Sample Code
Linux* Tutorial: PDF
Windows* Tutorial: PDF
Sample: pre-built matrix C++ matrix multiplication application. The pre-built application is available from the Project Navigator when you first launch Intel VTune Profiler. You can access the sample code from:
Demonstrates: Iterative application optimization with VTune Profiler, finding algorithmic and hardware utilization bottlenecks
Performance issues: memory access, vectorization
Analyses used: Performance Snapshot, Hotspots, Memory Access, HPC Performance Characterization, Microarchitecture Exploration
Analyzing an OpenMP* and MPI Application - C++ Sample Code
Linux* Tutorial: HTML
Sample: heart_demo C++ application that simulates electrophysiological heart activity. You can access the sample code at https://github.com/AlexeyMalkhanov/Cardiac_demo.
Demonstrates: Identifying issues in a hybrid OpenMP and MPI application.
Analysis/tools used: Application Performance Snapshot (APS), Intel Trace Analyzer and Collector, and VTune Profiler's HPC Performance Characterization analysis
