Prime factorization is useful and crucial for public-key cryptography, and its
application in public-key cryptography is possible only because prime factorization has
been presumed to be difficult. A polynomial-time algorithm for prime factorization on a
quantum computer is given by P. W. Shor in 1997. In this work, a linear-time solution
for prime factorization is given on a kind of biochemical computational devices - tissue
P systems with cell division, instead of physical computational devices.

In this paper we report a work-in-progress whose final target is the implementation of tissue-like P system in a cluster of computers which solves some instances
of the segmentation problem in 2D Digital Imagery. We focus on the theoretical aspects
and the problem of choosing a maximal number of application of rules by using Integer
Linear Programming techniques. This study is on the basis of a future distribution of the
parallel work among the processors.

We prove that uniform families of P systems with active membranes operat-
ing in polynomial time can solve the whole class of PP decision problems, without using
nonelementary membrane division or dissolution rules. This result also holds for families
having a stricter uniformity condition than the usual one.
