The Grid Projects in China Vega Grid Project ( ICT, MOST) National High Performance Computing Environment funded by 863 program (Many participants, MOST) Scientific Data Grid. (CAS, MOST) HEP data grid.(IHEP) Grid infrastructure building (MOE)

Overview of China ’ s Grid Project Build a superserver for major grid sites. Build a few of HPC centers. Develop system software for the Grid system. Develop demo applications on the Grid. Build 2Gbps interconnection among 100 university.

The Vega Project 1. Design goals: Design and implement Grid-level software. Build a national-scale infrastructure supporting HPC. Develop application running on testbed. 2. Grid-oriented superservers — Dawning 4000, 5000,etc. 3. Service Grid

Stress Distribution of 3800TEU

500hPa Contours in Weather Forecasting

The Vega Grid Topology It is Router-centered structure:

The Vega Grid Computing Protocol

The Vega OS Vega OS overview 1, A user-level middleware running on client machine Vega GOS constructed by 2 components: GOS and gnetd - GOS is a daemon running on client machine. - gnetd is a daemon on grid server response to client commands.

Grid process and Grid thread - Grid process is a unit for managing the whole resource of the Grid. - Grid thread is a unit for executing computation on the Grid.

2, Vega APIs introduction Vega GOS APIs - GOS APIs for application developers grid(): constructs a Grid process on client machine. gridcon(): grid process connects to Grid system. gridclose(): close a connected grid. ……

gnetd APIs for service developer on Grid servers - grid_register(): register a service to Grid. - grid_unregister(): unregister a service. …….

- A GOS-based application. - No central control - shell commands: > gsub > gstat > gkill, …… The Vega Grid Batch System

- All kinds of resources registered in Grid. > Computational resources: cycles, mem, disk, networks …… > software: DB, CAD …… > services: ftp, http, mail ……

Global Batch System in Vega Grid

Travel-An Online Transaction system An online transaction system----travel in China - GOS-based application - 4 different basic services registered in the Grid. * Wheather forecasting * airline ticket booking * sight spot ticket booking * charging - Putting these 4 services into an application

The National HPC Project Overview - Set up 9 HPC sites across China - Interconnected these 9 sites with available networks ( Cernet & NSTTet) - equipped each site with Dawning 2000/3000, Galaxy 3(20Gflops), Sunway 1(460Gflops), PC-cluster(8Gflops)

International Cooperation Joint research supported by European and China. Source sharing - Computing power - Database - Software tools - Application software

The Scientific Data Grid Project Build on the top of scientific databases. Belong to CAS, but open to the world. Plan to provide service in

Scientific Database(SDB) SDB funded by CAS since SDB is a collection of multiple disciplinary databases, including chemistry, biology, geography, astronomy, ecology, etc. By 2005, there are member institutions across China databases which is distributed and heterogeneous. - 10TB+ data volume size.

Why do SDG? Resource level — sharing and development. - make data more accessible. - data integration - and more easy to do: data->information->knowledge. Application level — emerging applications - can do what we can not do before. - cross multiple databases/multiple disciplines. - require more resources ( cycles, bandwidth, instrument, etc.)

Tasks Build testbed - one data center - and three sub data center. Middleware - information service - security - user interface Applications - Chemistry/Geo- science/astronomy/biology …
