I'm trying to understand the differences between controlling kernels and subkernels.
I created 3 local kernels (kernel configuration options > add), each using a maximum of 8 local subkernels.
However on the Wolfram User Portal my license reads
Controlling 2 Computing 8
So what are these "controlling kernels" ? Is there a limit on local kernels that can be started ?
Cf. This question on the same topic, but the answers appear contradictory. Following one of these answers, I don't understood how I am allowed to run 3 local kernels.
Additionally, what is the difference between launching 1 front-end and having many local kernels and launching many front-ends each with only one local kernel ?
