MacMPI is a tool (inspired by and based on tmux-mpi) that can be used to launch MPI applications, opening a new terminal window with one tab per MPI rank, attaching each tab to the corresponding rank. MacMPI integrates with the iTerm2 terminal on macOS.
This allows for debugging MPI applications by launching lldb or gdb with MacMPI.
