Kernels

Kernels
gives the list of running kernels available for parallel computing.
  • On a multicore computer, kernels are normally launched automatically when needed for a parallel computation.
  • All available kernels are by default used for all parallel computations.

Close all kernels:
Launch copies of the previously running kernels:
ParallelEvaluate by default does one evaluation on each kernel:
$KernelCount gives the number of running kernels:
If no kernels are available, most parallel calculations are done sequentially:
