$ConfiguredKernels

is the list of kernels that are configured to be selected for remote or parallel computing.

Basic Examples  (1)

The default kernel configuration:

Wolfram Language code: $ConfiguredKernels

Applications  (3)

Assignments to $ConfiguredKernels are remembered between sessions:

Wolfram Language code: $ConfiguredKernels = { KernelConfiguration["localhost", "KernelCount" -> 4], KernelConfiguration["prokyon", "KernelCount" -> 4, "KernelCommand" -> "wolfram132"] }

In a new session, the value is restored:

Wolfram Language code: Quit[]
Wolfram Language code: $ConfiguredKernels

Remove any persistent value by reverting $ConfiguredKernels to its default:

Wolfram Language code: Unset[ $ConfiguredKernels ]

Create a new kernel configuration based on an element of $ConfiguredKernels:

Wolfram Language code: $ConfiguredKernels[[1]]
Wolfram Language code: %["KernelCount"]
Wolfram Language code: new = KernelConfigurationEdit[$ConfiguredKernels[[1]]]
Wolfram Language code: new["KernelCount"]

To be able to refer to the new configuration by name, append it to $ConfiguredKernels:

Wolfram Language code: AppendTo[$ConfiguredKernels, new]

Obtain the configuration by name:

Wolfram Language code: KernelConfiguration["Local 1"]
Wolfram Language code: %["KernelCount"]

Properties & Relations  (1)

LaunchKernels[] uses the list $DefaultParallelKernels, not $ConfiguredKernels:

Wolfram Language code: $DefaultParallelKernels
Wolfram Language code: LaunchKernels[];$KernelCount
Wolfram Language code: $ConfiguredKernels
