Overview / Usage
Intel® VTune™ Profiler is a feature-rich tool for identifying CPU performance bottlenecks. Whether the cause is poor threading concurrency, memory access issues, I/O waits, or simply unnecessary instructions, VTune can help you find them quickly.
Methodology / Approach
I will demonstrate how to use Intel® VTune™ Profiler to analyze performance of a simple ray tracer and identify bottlenecks in the threading implementation and data access patterns.
I will also show performance after these problems have been fixed, highlighting the importance of CPU analysis.
