This project is a parallel implementation of the N-body simulation using a hybrid model of MPI (Message Passing Interface) and OpenMP (Open Multi-Processing). It is designed to run efficiently on high-performance computing (HPC) clusters.
The simulation uses MPI for communication between nodes in a distributed environment and OpenMP for multi-threading within a single node. The N-body problem involves calculating the motion of a group of celestial objects interacting with each other gravitationally. It is a computationally intensive task that benefits greatly from parallel processing.
The project contains the following main files:
nparticle.c: This is the main C source file, which includes the parallel N-body simulation code.Makefile: This file is responsible for automating the build process of the project.nparticle-script.sh: This Bash shell script is used to automate the build and execution of the program on an HPC cluster.
You can build the project using the provided Makefile:
make
To execute the program, use the provided Bash script. The script takes the maximum number of MPI processes and OpenMP threads as inputs:
./nparticle-script.sh <MAX_MPI_PROCESSES> <MAX_OMP_THREADS>
Remember to replace placeholders <MAX_MPI_PROCESSES> and <MAX_OMP_THREADS> with the maximum number of MPI processes and OpenMP threads.
Results will be generated for different combinations of MPI processes and OpenMP threads, which you can use to analyze the performance of the parallel implementation.
