Kernels

Kernels
gives the list of running kernels available for parallel computing.
MORE INFORMATION
  • 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.

Scope   (1)
Launch the default set of kernels:
Give the list of currently running parallel kernels:
Close all running parallel kernels:
No kernels are running:
Generalizations & Extensions   (1)
Remember the list of running kernels:
Close all kernels:
Launch copies of the previously running kernels:
Properties & Relations   (2)
ParallelEvaluate by default does one evaluation on each kernel:
$KernelCount gives the number of running kernels:
Possible Issues   (1)
If no kernels are available, most parallel calculations are done sequentially:
