Summary:	make sure RNG seeds and run number show up on ConfigStore output

Description Tom Henderson 2009-01-20 00:42:02 EST

reminder-- the point of ConfigStore is to dump all of the pertinent simulation attributes in use for a given simulation run, and RNG seed and run number are two of the most important parameters to log, for reproducibility.

Comment 1 Mathieu Lacage 2009-01-20 08:07:45 EST

The real issue here is that the outout pf GtkConfigStore+ConfigStore is a text file which contains the attributes of all instanciated objects in a simulation but:
1) there is no object which contains the global seed+run number used
2) if there was such an object, we would have to hook an instance of it artifically in the global attribute namespace

Another option would be to extend the text file format to include also the default value of every object attribute and all global values.

agree, but I thought you might someday add support for defaults and globals

I thought this was part of the eventual plan to finish ConfigStore.

we should change the title of this bug report to reflect this then.

I believe that we do have a global for the run number and the rng seed. We just need to add support for globals on config stores
