Execute $ConfiguredKernels to find out how many Kernels are available
on your system.

?$ConfiguredKernels

$ConfiguredKernels is the default list of kernels that are configured
to be launched for parallel computing. >>


The Documentation Center states, for $ConfiguredKernels, "On a
multicore computer the list typically includes as many local kernels
as there are cores, up to a limit defined by license availability."

 This program will often run overnight or even for more than a day. I figur=
