ppyd-gol

A basic implementation of the Game of Life using MPI.

Cmake 3.28 is required - you need the ppa (https://apt.kitware.com/)

Compilation

To compile the project, please run the following commands:

mkdir build
cd build
cmake ..
make -j 32

Execution

From the build directory, you can run the following commands:

src/main/gol

mpirun -n 9 src/main/par_gol

Debugging

GDB

GDB is a powerful debugger that integrates well with CLion. You can run it by debugging a CMake run configuration in CLion.

Alternatively, you can run it from the command line (from the build directory):

$ gdb src/main/gol
(gdb) run
...
(gdb) exit

Valgrind

Valgrind is a really cool tool for detecting memory leaks and other reasons your program might crash.

Valgrind is also available in CLion as another option alongside debugging, but you can run it from the command line as well.

Sequential

valgrind src/main/gol

Parallel

When running with MPI, Valgrind may produce some MPI-related warnings that can be ignored:

mpirun -n 9 valgrind src/main/par_gol

Experiment execution

1. Create a WANDB account wandb.ai
2. Install WANDB locally using pip
3. Run wandb login and paste in your token
4. Create a sweep.yaml
5. Run wandb sweep -p <project> -e <entity> to create the sweep
6. Create a available_processes.txt inside executor with the number of cores available on the machine
7. Run nohup <sweep agent cmd> & as many times as required from executor
