KernelObject

KernelObject[…]

represents a kernel available for parallel computing.

Details

  • Kernel objects represent running kernels on a local or remote computer system.
  • Kernel objects are created with LaunchKernels and terminated with CloseKernels.
  • KernelObject[…]["Properties"] gives the list of all supported properties or settings of the given kernel configuration.
  • KernelObject[…]["property"] gives the value of the specified property for the given kernel configuration.
  • KernelObject[…][All] gives an association of propertyvalue pairs for all properties of the given kernel object.

Examples

open all close all

Basic Examples  (1)

Scope  (2)

Launch a local parallel subkernel:

Display information about the kernel object:

Give the list of all known properties:

Give the value of a specific property:

Give an association of all property-value pairs:

Obtain a kernel object:
