[Users] Changing I/O parameters between simulations restarts

Hi,

When running long simulations with checkpointing, it might sometimes be useful to change certain parameters, especially I/O (e.g. the frequency of outputting a certain variable). Is this possible in Cactus/Simfactory? I notice that upon recovery (in the next re-start) Simfactory reads the parameters from a checkpoint file, not from any of the parfiles dumped within the job directory.

Any suggestions/responses will be highly appreciated.

Thank you, Dumsani
