The High Level Architecture (HLA) as a well-known IEEE standard for developing parallel and distributed simulation systems has been around for many years. In this paper, Runtime Infrastructure (RTI) of HLA is re-evaluated in the light of the current trends in many-core processor architectures. The future many-core processor architectures will contain thousands of cores connected with on chip networks. Such network on chip (NoC) architectures will not only be built as electronic networks but also as photonic networks. The communication links are established by using scalable communication patterns which define how the light paths to be setup in a 2D photonic network. In other words, RTI specific communication patterns orchestrate the underlying photonic network both to guarantee contention-free network operation and to utilize the bisection bandwidth available on the photonic torus. Time and data distribution management related algorithms are especially subject to this paper. Both the Greatest Available Logical Time (GALT) calculation algorithm and timestamp order (TSO) message delivery are carried out in small number of communication steps on 2D photonic torus. The approach taken in this work is based on hardware and software co-design.
