The earlier foil was overwhelming. It was stated in the presentation and I agree. In an attempt to make it less so, I removed the research content and combined MPI and OpenMP so that we have fewer boxes.
It will be good if someone who knows how to use PPT smart art will make the outside frame smaller.

9. Intel® Parallel Advisor

10. Intel Parallel Advisor
Intel Parallel Advisor helps developers identify and experiment with parallel opportunities in existing programs
By using Parallel Advisor, the developer can evaluate the return of their investment (performance benefit vs. the cost of transitioning to parallelism) before committing to a course of action…

11. Intel Parallel Advisor
As the user works through the tool, Parallel Advisor analyzes the data collected during the execution of the user’s program:
Survey – Helps the developer focus on the hot call trees and loops as locations to experiment with parallelism.
The developer will insert Advisor annotations into their sources to describe their parallel experiment.
Suitability – Helps developer evaluate the performance of their parallel experiment by displaying the performance projection for each parallel site and how each site’s performance impacts the entire program.
Correctness – Helps the developer by identifying data issues (races) of their parallel experiment.
Annotation insertion is necessary for Suitability & Correctness tools
Annotations are macros that do not impact the users applications when Advisor is disabled/not present – they become “empty statements”.
A parallel experiment or parallel modeling is a set of “Annotated tasks” within an “Annotated Site”. Tasks and sites can be in different files, different projects (site in image project, tasks in library).
Annotation pairs (site, task, locks) can not span scope BOUNDARIEs

This helps the developer identify which parallel experiment to focus on.
MySite1 has 6 errors and 3 warnings (Correctness) and self Max Gain of 7.5x – the program could benefit 1.8x
