OpenMP Introduction

This repository by nguyenpanda contains C/C++ code and examples for the Parallel Computing course taught by Dr. Thanh-Dang Diep, who is a lecturer at Ho Chi Minh City University of Technology (HCMUT), VNU-HCM.

Build & Run

cd <dir> # e.g., performance, test, ...
make execute

Tip: run make help to see all available targets defined in each Makefile.

• The top-level repo_root/Makefile is the primary entry point.

• To override OpenMP or runtime environment variables for a specific exercise, edit .env file.

• To add or tweak compile flags (e.g., CXXFLAGS, LDFLAGS, INCLUDES), edit Makefile in <dir>. Or adding via command line while compile using EXTRA_CXXFLAGS or EXTRA_MACRO (e.g., cd performance && make execute EXECUTE=build/BM_MatAdd.exe EXTRA_CXXFLAGS="-O3 -Ofast -Wall")

Directories

A quick map of what each directory (<dir>) demonstrates:

Name	Description	Note
include	Contains the core of this repo	The implementation is done in header file, because of C++ template
performance	All benchmarks are done in this repo	Using Google Benchmark and contains its own
test	Testing the correctness of algorithm	Using Numpy
