Hi.

I am not sure is that about Linux or on Windows system.

But, since I am using for Linux, I can suggest few things -

(a) The need of Benchmark & it's FLOW-DIAGRAM, please refer some Intel VTune slides, check on google.

(b) Comparison between other profilers, w.r.t overhead and system analysis.

(c) Intel VTune Advantages.

(d) Hotspots & Bottlenecks

(e) Generating Call Graphs

(f) Generating Event Based Sampling (EBS)

(g) Theory of Constraints (TOC) & CPI Iterations

(h) FRONT-END optimizations - CPI analysis for DTLB, Cache, Buffers & System Bus Utilizations

All above contents & documents, one can get in google. Please refer my previous replies for VTune within Intel forum. I did had mention the links & references.

Happy Learning.

I would emphasis the fact that without a good tool to profile your benchmarks, you will have no idea where or how to optimise you code base. I would add that optimisation, like testing, is something that should happen from day zero of development and not at a late stage.

Otherwise, I think the above covers everything pretty well. Oh yes: screen shots, as Napoleon said: Un croquis vaut mieux qu'un long discours.
