an experiment will not define new descriptors but rather point to an existing descriptor(s). IMO (correct me if I'm wrong),
Experiment = Application + Input value(s) for application + Configuration data for managing job Application = Service Descriptor + Host Descriptor + Application Descriptor Thus for an experiment it involves quite the amount of data of which needs to be specified. Thus it is easier to make a copy of it rather than asking the user to specify all of the data again when only there are very few changes compared to original experiment. Perhaps the confusion here is the word "clone"? On Fri, Jan 17, 2014 at 10:20 AM, Amila Jayasekara <[email protected]>wrote: > This seems like adding new experiment definition.
