Can't PNN Learner use more than one core of CPU?

Hi,

  I'm starting to use Knime to train a Neural Network with PNN Learner and I saw that it only uses one core of CPU while running the learning. The problem is that I have a huge ammount of data (somethig like 500000 rows of input) and two parameters to predict (with 5 working as input of the Learner).

  Is it possible this node run with more than one core? Or is there another way to run predictions using Parallel Chunk, for example?

  Sorry if this questions are trivial, but I'm starting now.

Grateful,

E Meirelles.
