Title:
Overview of the National Center for High Performance Computing (NCHC) and the National Center for Typhoon and Flooding Research (NCTFR) in Taiwan
Abstract:
Taiwan's National Center for High-Performance Computing (NCHC) is the nation's leading source for high-performance computing (HPC) hardware, software, and networking resources. NCHC is a non-profit organization that provides comprehensive computing and grid-network services to all of Taiwan. The government of Taiwan recently implemented the Challenge 2008 plan, a comprehensive six year island-wide plan of development. The purpose is to foster the creativity and talent that Taiwan needs to achieve success in the new world economy. The NCHC played a critical part in fulfilling the Challenge 2008 goals by building the Taiwan Advanced Research and Education Network (TWAREN) and developing its twin project, the Knowledge Innovation National Grid (KING). These projects will transform Taiwan into a world-class knowledge center. We hope to use these resources to form global alliances and create an environment where HPC resources are shared among all nations. Several globally collaborative projects will be described.*

The major objectives of the proposed National Center for Typhoon and Flooding Research (NCTFR) are: (1) developing Taiwan Model for the Earth System (TMES) (including atmosphere, hydrology, ocean and soil) as tools to predict/study weather, climate, flooding, typhoon, pollution, landslide, etc; (2) collecting and analyzing observational data and numerical simulations to understand the basic sciences involved; (3) promoting computation fluid dynamics and large- scale computing facility in Taiwan; (4) recruiting young scientists; and (5) making NCTFR be a leading research institute.

We will also briefly discuss the Purdue atmospheric models** and WASH123D***, which will be used as the foundation in order to develop TMES.

*International collaboration will be an important component to both Centers.

** We will briefly present the basic structures, numerical schemes, and physics of the regional climate model, nonhydrostatic models, snow-soil model, and others developed at Purdue and their application to air pollution, flow over complex terrain, severe weather, regional climate, etc.

*** We will present the development of a physics-based distributed watershed model (WASH123D), which covers multimedia of river networks, overland regime, and subsurface media with control structures and operation rules. The model also includes multi-processes of hydrological and biogeochemical cycles.
