The problem is the following. I want to create a notebook with 4 cells. Assign each cell to a specific kernel and then run 4 tasks in parallel. When I do this manually everything is fine. However when i close the notebook, saving it, and reopen it, everything resets and i need to reassign the cells again. Is there a way to actually save the cell options?
Edit: I would like to correct myself. Notebook format .nb saves the setting, but creating a script with .m extension is not able to save kernel assignments.
