Hi all,

I am not sure I understand what the output-xxxx folders do under each individual simulation folder.

Suppose we "create-submit" a new simulation named test.

The results will appear in the output-0000 folder under the folder "home/username/simulations/test/".

OK, great.

Suppose now we want to re-run that simulation.

And suppose we want to re-run it from scratch and not continue from a previous checkpoint (e.g. maybe we forgot to save some output we needed).
The skeleton is already created, so we can just use the command submit this time.

The results will appear in the output-0001 folder.

Is the above understanding correct?

Questions:

When we submit again the simulation for the re-run, do we have to specify the same computational resources?

I.e. is this info something already encoded in the simulation's skeleton and therefore we should keep it fixed for consistency?

Does the skeleton of the simulation also fix what quantities are saved and therefore if we forgot to save some quantity we have to create a new simulation skeleton?

Additionally, from what I understand, the output-xxxx folders mainly handle different checkpoints of a larger simulation that could take weeks or months.

Does the user have to do anything to combine all the information from the checkpoints, or is this handled automatically by ETK / SimFactory?
Is there any advice on best practices regarding this scenario?

Best,
Panayotis
