The present invention provides an apparatus and/or method for modular, scalable and nestable parallel data processing and process control systems from molecular to module/enclosure level, comprised of calculable inter- and intra-modular processing time standards and shorter look-ahead propagation paths; based on regular and irregular hexagonal and dodecagonal prisms, derivative dumbbells and variants as actual and/or approximated tilings/tessellations which may be arranged in columns, rows, stacks and arrays with or without rounding and/or a sliding fit. Non-sliding fit systems are fundamentally solid. Sliding fit systems modules have a central cavity with systems as follows: cage assembly, optional patch panels, anchoring, thermal management, interconnect enclosures, power, hot swap, fail over, positioning, and interconnects with optional quick disconnects and retractors. Optionally, module arrays store on dollied pallets in ramped warehouse rack shelving with optional catwalks, mezzanines, walls and roofs for build out and new construction.
