In this paper we study the Local Memory P-RAM. This model allows unit cost communi- cation but assumes that the shared memory is divided into modules. This model is motivated by a consideration of potential optical computers. We show that fundamental problems such In recent years, the technology of optical communication has gained importance due to high bandwidth and data rate requirements.
