Application tasks are complex and diverse, which need High Performance Computing(HPC) to solve. To solve the problem that computing efficiency is huge different when they run in different architecture because of different application tasks having different computing features. The Processor-Memory-Communication(PMC) resource requirements of application tasks are perceived to get PMC operator grain, the matched architecture is assigned to the applications. Hypergraph is used to describe the application structure and architecture, and hypergraph isomorphism principle is used to build super-mixed heterogeneous architecture. Experimental results show that reconfigurable architecture which operator grain perception driven has characteristic of high computing efficiency and low energy consumption.
