OpenMP-C-Docker Setup

This repository contains multiple C and C++ files utilizing OpenMP for parallel programming. The setup includes a Docker container with all required tools to compile and run these files.

Setting Up the Docker Container

1. Build the Docker image:

   docker build -t openmp-c-mpi-container .

   It will automatically compile the c and cpp files.

2. Run the container interactively:

   docker run --rm -it -v $(pwd):/usr/src/app openmp-c-mpi-container bash

   The -v $(pwd):/usr/src/app flag mounts the current directory into the container so that changes persist.

Running the Executables

After compilation, each .c or .cpp file will have a corresponding .out executable. Run them using:

./<filename>.out

For example, if you have a file named program.c, compile and run it as follows:

./program.out

Using OpenMP

OpenMP is enabled by the -fopenmp flag in the compilation settings. Ensure that any #pragma omp directives in your source files are correctly formatted and placed.

Notes

• Edit the source files on your host system, and they will be reflected inside the container due to the mounted volume.
• Make sure to add new .c or .cpp files in the repository and rerun make to compile them.
