Simulating a Family of Tissue P Systems Solving SAT on the GPU

In order to provide e cient software tools to deal with large membrane systems, high-throughput simulators are required. Parallel computing platforms are good candidates, since they are capable of partially implementing the inherently parallel nature of the model. In this concern, today GPUs (Graphics Processing Unit) are considered as highly parallel processors, and they are being consolidated as accelerators for scienti c applications. In fact, previous attempts to design P systems simulators on GPUs have shown that a parallel architecture is better suited in performance than traditional single CPUs. In 2010, a GPU-based simulator was introduced for a family of P systems with active membranes solving SAT in linear time. This is the starting point of this paper, which presents a new GPU simulator for another polynomial-time solution to SAT by means of tissue P systems with cell division, trading space for time. The aim of this simulator is to further study which ingredients of di erent P systems models are well suited to be managed by the GPU.Junta de Andalucía P08-TIC04200Ministerio de Economía y Competitividad TIN2012-3743
