WOLFRAM

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 allclose all

Basic Examples  (1)Summary of the most common use cases

Out[1]=1

Give the list of all running parallel kernels:

Out[2]=2

Close all running parallel kernels:

Scope  (2)Survey of the scope of standard use cases

Launch a local parallel subkernel:

Out[1]=1

Display information about the kernel object:

Out[2]=2

Give the list of all known properties:

Out[3]=3

Give the value of a specific property:

Out[4]=4

Give an association of all property-value pairs:

Out[5]=5

Obtain a kernel object:

Out[1]=1

Display information about the kernel object:

Out[3]=3

Give the list of all known properties:

Out[4]=4

Give the value of a specific property:

Out[5]=5

Give an association of all property-value pairs:

Out[6]=6

Applications  (2)Sample problems that can be solved with this function

Close all kernels:

Out[1]=1

Launch copies of the previously running kernels:

Out[2]=2

Close a particular kernel:

Out[1]=1
Out[2]=2
Out[3]=3

Possible Issues  (1)Common pitfalls and unexpected behavior

Kernel ID values are not necessarily contiguous:

Out[1]=1
Out[2]=2
Out[3]=3
