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.
