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. MPI Supported by Parallel Composer

Intel® Parallel Advisor 11/15/2018

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…

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

Intel Parallel Advisor – Survey The Survey Report shows the Total & Self Time of call sites & loops Drill down into the Source code Survey – Helps the developer focus on the hot call trees and loops as locations to experiment with parallelism. Top down list of call sites & loops

Intel Parallel Advisor – Suitability Impact to entire program Proposed parallel sites How to maximize the performance benefit of the selected site Annotations that occur within the selected site 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. Help when you need it

Intel Parallel Advisor – Correctness Problems and Messages Filters Drilling down into an observation Correctness – Helps the developer by identifying data issues (races) of their parallel experiment. Observation problem sets

Parallel Advisor – Summary Report Displays the developer’s annotated parallel sites & tasks, with their associated Suitability performance projection and Correctness data-sharing problems: 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

Intel Parallel Advisor Offers guidance through the methodology. Annotation Wizard assists with the creation and insertion of Advisor annotations. Workflow window - The current step is high-lighted.
