摘要

鉴于卡特里娜飓风在新奥尔良和周边教区造成的后果,预测热带风暴和飓风的需求成倍增加。准确的预测可以帮助决策者实施适当的疏散计划,从而保障公民的福祉。海岸建模是用于预测飓风、风暴潮和洪水的重要工具。在众多已实施的模型中,北卡罗来纳大学的 ADCIRC 项目似乎大有可为。我们的研究目标是多方面的。首先,我们确定了 ADCIRC 模型目前存在的局限性。我们通过各种方法实现了这一目标,包括在单个集群和多个集群上进行 ADCIRC 基准测试,以及在单个集群上对 ADCIRC 进行 gprof 分析。然后,根据从这些工作中获得的信息,我们提出了适当的改进建议,以优化 ADCIRC。随着这些目标的实现,我们希望 ADCIRC 将成为在胁迫情况下制定精确疏散计划的重要工具,帮助挽救无数生命。

Towards a faster and improved ADCIRC (ADvanced Multi-Dimensional CIRCulation) model
Given the aftermaths of Hurricane Katrina in New Orleans and the surrounding parishes, the need to predict tropical storms and hurricanes has increased multifold. Accurate predictions may assist decision makers to implement appropriate evacuation plans necessary for the wellbeing of citizens. Coastal modeling is a key tool used to foresee hurricanes, storm surge, and flooding. Of the many models implemented, ADCIRC, a project of the University of North Carolina, seems to hold much promise. Our objectives in this study were multifold. First, we ascertained the current limitations of the ADCIRC model. We achieved this goal through a variety of means including ADCIRC benchmarks on single and multiple clusters as well as a gprof profile of ADCIRC on a single cluster. Then, based on the information obtained from these efforts, we suggested appropriate improvements to optimize ADCIRC. With the achievement of these objectives, we hope ADCIRC will become a vital tool in developing accurate evacuation plans under duress that will aid in saving a countless number of lives.

期刊介绍: The Journal of Coastal Research (JCR) is one of the leading international journals for coastal studies and processes, and is published bi-monthly by the Coastal Education & Research Foundation [CERF]. By covering the entire field of coastal research, the JCR encompasses all subjects relevant to natural and engineered environments (freshwater, brackish, or marine) and the protection/management of their resources in the vicinity of coastlines of the world. Even though the journal broadly focuses on immediate shoreline zones, the JCR also embraces those coastal environments that either reach some indefinite distance inland or that extend seaward beyond the outer margins of the sublittoral (neritic) zone. The JCR disseminates accurate information to both the public and research specialists around the world on all aspects of coastal issues in an effort to maintain or improve the quality of our planet''s shoreline resources.
