Systems, methods, and other embodiments associated with avoiding resource blockages and hang states are described. Each of the phases in the QA life cycle corresponds to one or more phases in a computer application development life cycle. The SLM is programmed or CGH configured with a modulation pattern that is determined by the substrate topography and desired pattern. Therefore, supercasting can be minimized by combining fabric destination addresses with like signatures. The master stations exchange information with each other about a communication bandwidth being used in the first CSMA period, thereby calculating a communication bandwidth which can be used by each communication system in the first CSMA period, based on the information.
