This booklet constitutes the refereed court cases of the second one foreign convention, TPNC 2013, held in Cáceres, Spain, in December 2013. the nineteen revised complete papers awarded including one invited speak have been conscientiously reviewed and chosen from forty seven submissions. The papers are prepared in topical sections on nature-inspired versions of computation; synthesizing nature through computation; nature-inspired fabrics and data processing in nature.

This poses a restriction on the smoother that can be used in the parallel code. 2 can not be parallelized efficiently, at least on unstructured grids (for structured rectangular grids see [3]). Therefore the parallel implementation currently uses either point Jacobi or inexact Block-Jacobi smoothers (with one or several steps GS or ILU as inner solver). The data partitioning uses a unique mapping of the elements (of all levels) to the set of processors. For each element t assigned to a processor p, this processor holds also a copy of the nodes of t and of the father element of t and its nodes.
