$ConfiguredKernels

As of Version 12.3, $ConfiguredKernels has been superseded by $DefaultKernels.

$ConfiguredKernels

is the default list of kernels that are configured for remote or parallel computing.

Details

  • 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.

Basic Examples  (1)

The default parallel kernel configuration:

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

Possible Issues  (2)

If any kernels are already running, LaunchKernels[] does not launch the default kernels:

Close all running kernels, then launch the default set of kernels:
