MPI Sorting and Stencil Computation

This project contains MPI implementations for sorting and stencil computation.

Setup

1. Update and upgrade your system: sudo apt-get update sudo apt-get upgrade

2. Install OpenMPI: sudo apt-get install libopenmpi-dev sudo apt-get install openmpi-bin

3. Verify installation: mpicc --version mpiexec --version

Compilation and Execution

Sorting Program

1. Compile: mpicc sort_all.c -o sortout

2. Execute: mpiexec --oversubscribe -np 4 ./sortout

Stencil Computation

1. Compile: mpicc stencil_all.c -o stencilout

2. Execute: mpiexec --oversubscribe -np 1 stencilout 100 10 50 1 1

Note

The --oversubscribe option allows more processes than available slots in Open MPI.
