Comment (by eschnett):
The design of simfactory is to hide the details of running a simulation as much as possible. Ideally, one would point to an executable and a parameter file, and receive the results four weeks later. Technically, this is not yet reliably possible.
In my mind, a simulation is defined by the source code and the parameter file. Changing these should not be possible. If one wants to change a parameter file or an executable (which are valid requests), then this defines a new simulation. For example, what happens if the new parameter file wasn't good? Or, how can one ensure that a simulation is exactly reproducible by someone else?
I would thus change the request to "allow using checkpoint files from a different simulation". Upon creating the simulation, simfactory would copy (hard link if possible) the checkpoint files.
