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

The default kernel configuration:

In[1]:=1
✖
https://wolfram.com/xid/0tq0swkav7ykro-pcfbx7
Out[1]=1

Applications  (3)Sample problems that can be solved with this function

Assignments to $ConfiguredKernels are remembered between sessions:

In[1]:=1
✖
https://wolfram.com/xid/0tq0swkav7ykro-u1qjt2
Out[1]=1

In a new session, the value is restored:

In[2]:=2
✖
https://wolfram.com/xid/0tq0swkav7ykro-lhz1n6
In[3]:=3
✖
https://wolfram.com/xid/0tq0swkav7ykro-09d3ic
Out[3]=3

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

In[1]:=1
✖
https://wolfram.com/xid/0tq0swkav7ykro-h1cprw
Out[1]=1

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

In[1]:=1
✖
https://wolfram.com/xid/0tq0swkav7ykro-bw5lje
Out[1]=1
In[2]:=2
✖
https://wolfram.com/xid/0tq0swkav7ykro-pjtw0x
Out[2]=2
In[3]:=3
✖
https://wolfram.com/xid/0tq0swkav7ykro-prqndr
Out[3]=3
In[4]:=4
✖
https://wolfram.com/xid/0tq0swkav7ykro-8wep7w
Out[4]=4

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

In[5]:=5
✖
https://wolfram.com/xid/0tq0swkav7ykro-l0prvq
Out[5]=5

Obtain the configuration by name:

In[6]:=6
✖
https://wolfram.com/xid/0tq0swkav7ykro-phru9x
Out[6]=6
In[7]:=7
✖
https://wolfram.com/xid/0tq0swkav7ykro-y67lle
Out[7]=7

Properties & Relations  (1)Properties of the function, and connections to other functions

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