3 National Center for Supercomputing Applications Outline Historical Background Grid Computational Chemistry Production Environments Current Status Web Services Usage (Grid and Science Achievements) Brief Demo Future

4 National Center for Supercomputing Applications Motivation Software - Reasonably Mature and easy to use to address chemists questions of interest Community of Users - Need and capable of using the software Some are non traditional computational chemists Resources - Various in capacity and capability

5 National Center for Supercomputing Applications Background Qauntum Chemistry Remote Job Monitor ( Quantum Chemistry Workbench) 1998, NCSA Chemviz , NSF (USA) Technologies Web Based Client Server Models Visual Interfaces Distributed computing (Condor)

6 National Center for Supercomputing Applications GridChem NCSA Alliance was commissioned 1998 Diverse HPC systems deployed both at NCSA and Alliance Partner Sites Batch schedulers different at sites Policies favored different classes and modes of use at different sites/HPC systems

7 National Center for Supercomputing Applications Extended TeraGrid Facility

8 National Center for Supercomputing Applications NSF Petascale Road Map Track I Scheme Multi petaflop single site system to be deployed by 2010 Several Consortia Competing (Now under review) Track 2 Sub petaflop systems Several to be deployed until Track 1 is online First one will be at TACC ( 450 TFlops) Available Fall 2007 ( Processors/Cores) NCSA is deploying a 110 TFlops in April 2007 (10000 Processors/cores) Second subpetaflops systems being reviewed

9 National Center for Supercomputing Applications Grid and Gridlock Alliance lead to Physical Grid Grid lead to TeraGrid Homogenous Grid with predefined fixed software and system stack was planned (Teragrid) but it was difficult to keep it homogenous Local preferences and diversity leads to heterogeneous grids now! (Operating Systems, Schedulers, Policies, Software and Services ) Openness and standards that lead interoperability are critical for successful services

23 National Center for Supercomputing Applications Gridchem Middleware Service (GMS)

24 National Center for Supercomputing Applications GrdiChem Web Services Quick Primer XML is used to tag the data, SOAP is used to transfer the data, WSDL is used for describing the services available and UDDI is used for listing what services are available. Web Services is different from Web Page Systems or Web Servers: There is no GUI Web Services Share business logic, data & processes through APIs with each other (not with user) Web Services describe Standard way of interacting with web based applications A client program connecting to a web service can read the WSDL to determine what functions are available on the server. Any special datatypesdatatypes used are embedded in the WSDL file in the form of XML Schema. Universal Description, Discovery, and Integration. WSRF Standards Compliant.

30 National Center for Supercomputing Applications GMS_WS Authentication WSDL (Web Service Definition Language) is a language for describing how to interface with XML-based services. It describes network services as a pair of endpoints operating on messages with either document-oriented or procedure-oriented information. The service interface is called the port type WSDL FILE:
