Definition of Computational Science Computational science is a rapidly growing multidisciplinary field that uses advanced computing capabilities to understand and solve complex problems. •Three distinct elements: – Driven by the underlying science/engineering/humanities problems; – Solve the problems through simulations; – Using advanced computing technologies systems and infrastructure; Computational Science for NRM D. Wang Working Procedure Scientists /Engineers Complex problems Build system or conceptual models Computability /Capability Computational Scientists Scientists /Engineers Computer models (machine-understandable formats) Best/feasible solutions Understandable/Usable Model results Computational Science for NRM D. Wang Requirements and potentials Basic knowledge requirements • Underlying sciences/engineering • Mathematical modeling • Computer science Advantages and limitations • Need multidisciplinary collaborations Computational Science for NRM D. Wang Frontiers and Challenges (1) Existing problems in natural resource management A general framework or template for a variety of problems? • Dr. Gross’s talk Computational Science for NRM D. Wang Computing, computing Some fundamental computing terminologies Date structures Computer architecture Programming languages Operating Systems Algorithms Networking Advanced computing paradigms Distributed computing Parallel computing Grid computing & Internet Computing Computational Science for NRM D. Wang Frontiers and Challenges (2) Model characteristics Population (aggregated) model Individual based model Spatial explicit model Model integrations Multi-species model Model integrations Ecosystem modeling (multimodeling) Computational Science for NRM D. Wang Frontiers and Challenges (3) Model analysis Statistical model Information retrieval (data mining) Model result representation Date visualization / Data mapping (GIS) Date archive (Long term data, etc) Date standardization (NBII, metadata) Computational Science for NRM D. Wang Hey, I am a CS guy Something Interesting HPC (solve a large scale problem in a second?) Information sharing (Everyone in the world should see my results !!!) Information analysis (now I am sure I will not run into a black bear if I camp here!) Computational Science for NRM D. Wang
