Intel VTune & AMD uProf

Purpose

Guide agents through CPU microarchitecture profiling with Intel VTune Profiler (free Community Edition) and AMD uProf: hotspot identification, microarchitecture analysis, memory access pattern optimization, pipeline stall diagnosis, and roofline model analysis.

Triggers

• "How do I use Intel VTune to profile my code?"
• "What are pipeline stalls and how do I reduce them?"
• "How do I analyze memory bandwidth with VTune?"
• "What is the roofline model and how do I use it?"
• "How do I use AMD uProf as a free alternative to VTune?"
• "My code has good cache hit rates but is still slow"

Workflow

1. VTune setup (free Community Edition)
