In reply to Gyy_VE:
You are retrieving a whole set of data from the config_db at the beginning of the main_phase.
Afterwards you are starting the compare with 3 compare functions in parallel.
I do not see how the compare functions are implemented but I gues they are running in a forever loop.
In this case you have only 1 set of parameters. Looks like this is what you see. But you want to see a 2nd of parameters right?
