$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.

When no kernels are running, LaunchKernels uses $ConfiguredKernels as the default.
