Grid Middleware and Tools Integrating existing tools for molecular environmental applications: • Globus and GT2 (Argonne, USC, support from CLRC) • Grid toolkit • security, resource discovery • HARNESS (Oak Ridge, Reading, Emory) • heterogenous environment for plug-in applications • Fault tolerant MPI/ PVM • CCF and CCTL (Reading and Emory) • collaborative working, visualisation and steering • Web-based application portals (CLRC) • Data management and visualisation (CLRC and Reading)
GSI GridFTP Globus Integrated Portal Architecture Generic portal design using Globus and Web Services: Data Systems DataPortal Web Services Web Services HPCPortal Web Services Visualisation HPC Systems Working with GGF Grid Computing Environments Research Group
Example Grid Testbed IBM PPC (AIX, MyProxy, server) IBM cluster (Power, AIX, Web server) Beowulf (Pentium, Linux, PBS) LoadLeveler Commodity cluster (Alpha, Linux, PBS) IBM SP (Power, Loadleveler) Globus/ GT2/ HARNESS Condor SUN cluster (UltraSparc, Solaris, Condor, MDS)
Active Grid Services Web-based interfaces to generic Grid services using the Globus C API Develop Portal for molecular simulations: • Login/ logout • file transfer • temporary workspace • job submission • user profile management Compare to commercial Web services for B2B
Data Management • Use data to enhance understanding and streamline research procedures • Metadata creation and use • Automatic retrieval and archival of results • populate database • Mining and Fusion • e.g. different simulations for different length scales • simulation plus experimental data • Analysis, comparison with simulation • Visualisation
Data Processing and Collaboration on a Grid: • Tools: • Amira • CCF/ CCTL • CORE • COVISE • HARNESS • ManiCoral • VIVRE Collaborative Working and Visualisation Example shows COVISE: UK collaboration with HLRS Stuttgart
Collaborative Computing Frameworks Architecture • Collaborative Computing Frameworks (CCF): a suite of software systems, communications protocols and tools to enable collaborative, computer-based cooperative work • The CCF constructs a virtual work environment on multiple Internet connected computer systems to form a collaboratory • Collaborative Computing Transport Layer (CCTL): communication fabric that underlies the CCF • Plugin to HARNESS environment supporting distributed MPI/PVM environment, steering and metacomputing Applications CCF Tools ... Chat CB SW Audio DSM Virtual Desktop CCFDS CCFCF CCSM CCFX CCF(naming, white pages, uniform API) CCTL(multiway transport groups QoS) Internet (UDP,IP mcast), ATM etc
