2.1. Learning Objectives#
This chapter enables students to progressively develop their understanding and skills in OpenMP programming. By the end of this chapter, students will be able to:
Remember & Understand
Describe the structure and principles of MIMD architecture and its relevance to shared-memory parallel computing.
Explain the execution model of OpenMP, including the role of threads, teams, and synchronization points.
Apply
Implement parallel regions in OpenMP using the
parallel
andteams
directives to create SPMD-style programs.Use
barrier
,ordered
, and other synchronization constructs to coordinate thread execution safely and correctly.Apply OpenMP task constructs to express asynchronous and irregular parallelism in C/C++ programs.
Distribute workloads explicitly across threads using OpenMP directives like
single
,sections
,for
, anddistribute
.
Analyze
Differentiate between the use cases and performance implications of
parallel
,teams
, andtask
constructs.Analyze synchronization needs in a parallel program and determine appropriate mechanisms to avoid race conditions.
Inspect the impact of various work-sharing strategies on performance and load balance.
Evaluate
Evaluate the scalability and correctness of OpenMP programs under different architectural assumptions (e.g., multicore vs. multi-CPU).
Critique the suitability of selected OpenMP directives for specific parallel patterns or problem domains.
Create
Design parallel solutions for real-world problems by combining OpenMP directives effectively and modularly.
Develop optimized OpenMP programs that demonstrate good parallel design, proper synchronization, and balanced workload distribution.
