* `--p2p`: Use MPI Point-to-Point communication for halo data exchange, i.e. `MPI_Isend`, `MPI_Irecv` and `MPI_Waitall`.
* `--persist`: Use MPI persistent requets (created with `MPI_Send_init` and `MPI_Recv_init`) for halo data exchange (using `MPI_Startall` and `MPI_Waitall`).
* `--overlap`: Overlap communication and computation, i.e. compute inner cells while doing halo data exchange (Default).
* `--no-overlap': Do not overlap communication and computation.
* `--no-overlap`: Do not overlap communication and computation.
* `-x [X]`, `--nprocs-x [X]`: Use `X` processes in x-direction for MPI Cartesian communicator (optional).
* `-y [Y]`, `--nprocs-y [Y]`: Use `Y` processes in y-direction for MPI Cartesian communicator (optional).
* `-i [N]`, `--iterations [N]`: Do `N` iterations, creating `N` output files with the current state of the cellular automaton; Default: 1.
* `-g [G]`, `--generations-per-iteration [G]': Number of generations to simulate between output iterations; Default: 5000.
* `-g [G]`, `--generations-per-iteration [G]`: Number of generations to simulate between output iterations; Default: 5000.
For large numbers as arguments to the option `-g`, the suffixes 'k' or 'M' may be used. For example, `-g 50k` specifies 50-thousand and `-g 1M` specifies one million generations per output iteration.
