Start several gdb processes in terminal emulator in split screen modus

I'm using gdb to debug a parallel mpi-code 'prog'. For that I use a small number of processes, say 'M' and do something like

mpiexec -n M xterm -e gdb ./prog

This pops up M xterms with each of them running one gdb process on one of the files prog.
The resulting cluttering of the screen by individual windows can be rather cumbersome.
Is there any way, using any known split-window terminal emulator (say, terminator), such as to have the M gdb processes starting up in only one window, however split into M parts from start?

I faced a similar problem and have found tmpi which does exactly what you want: launch mpi debugging processes in M tmux terminal windows.

Clone the repository:

git clone https://github.com/Azrael3000/tmpi.git

then install with:

sudo ./tmpi/install.sh

which places the tmpi executable in /usr/local/bin

The tmpi executable and tmux must be in the path on all your servers.

Run a job with:

tmpi M gdb my_executable

where M is the number of processes that you want.

What you want is called a 'terminal multiplexer'; look into screen or tmux

EDIT: this is probably what you want; issue the following commands in your shell

tmux new-session -d bash     # start a bash shell
tmux split-window -v python  # start a python shell below it
tmux attach-session -d       # enter the tmux session
