$ConfiguredKernels

$ConfiguredKernels
is the default list of kernels that are configured to be launched for parallel computing.
  • On a multicore computer the list typically includes as many local kernels as there are cores, up to a limit defined by license availability.
  • Additional configurations for kernels on remote machines can be made available with the Wolfram Lightweight Grid and the Cluster Integration Package.
The default parallel kernel configuration:
When no kernels are running, LaunchKernels uses this list as the default to launch kernels:

When no kernels are running, LaunchKernels uses this list as the default to launch kernels:

If any kernels are already running, LaunchKernels does not launch the default kernels:
Close all running kernels, then launch the default set of kernels:
