Water is an origin of life, an essential factor for production, and a basis for ecology. Water resources not only relate to flood safety, drinking water safety, and food security, but also to economic, ecological, and national security. The natural water resources system as a giant complicated system has its natural evolution processes within a range of temporal and spatial scales in the environments. However, because of global climate changes and the intense impact of human activities at presentsuch as abnormally changing precipitation-the more water withdrawn from and wastewater discharged into rivers, the more evolution of natural water resources system is disturbed. What is more, water problems have happened frequently in some regions, especially in mega cities (like Beijing), such as serious water shortages, severe water pollution, and deterioration of the water eco
Abstract-Application tasks are complex and diverse, which need HPC (High Performance Computing) to solve them. The computing efficiency is hugely different when they run in different architectures, because different application tasks have different computing features. The PMC (Processor-MemoryCommunication) resource requirements of application tasks are perceived to get PMC operating grain, and the best matched architecture is assigned to the application. Hypergraph is used to describe the application structure and the computing architecture, and its isomorphic principle is utilized to build and demonstrate the super-mixed heterogeneous architecture. Experiments show that reconfigurable architecture based on operator grain perception has characteristic high computing and low energy consumption.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
