  1. Kepler in UCGrid • Requirements Characteristics: • Not many potential users of UC Campuses have programming experience • Many research problems need processes to finish them • With Kepler GUI, common users can easilycompose workflow and use UCGrid resources • Generate workflow xml files from Kepler GUI by dragging and dropping • The same xml file can be executed in different environments: local machine, cluster, Grid, etc… • Upload the xml file and execute from UCGrid Portal or command line

  2. Kepler Use Case in UCGrid • We will continue the current chemistry use case and demonstrate the capability of collaboration • The process to use Kepler and UCGrid • The advantages can be gotten from the use case. • After that, the analysis can be available for better understanding and future applications

  3. Collaboration of Kepler and UCGrid • UCGrid provides abundant computing and software resources for scientists • Kepler provides a bridge for scientists to easily utilize the above resources according to their domain problems • Scientists compose individual tasks by Kepler workflows and run them in UCGrid

  4. Usage Modes of Kepler in UCGrid • Kepler Application in UCGrid: Users model workflows from Kepler GUI, upload them to UCGrid portal, and execute them through Kepler batch-mode command • Kepler Globus Web Service in UCGrid: With UCGrid authentication, We can integrate user applications with UCGrid, their tasks be executed through deployed Kepler WS • Direct Execution from Kepler GUI: With UCGrid authentication, users can model workflows that submit jobs to UCGrid,and execute them from Kepler GUI

  6. Master-Slave Distributed Execution Framework • Utilize distributed resources to accelerate workflow execution • Smooth transitionbetween different execution environments, such as local, ad-hoc network, cluster, grid and cloud

  7. Cluster Job Submission Actors • Adaptable for different cluster schedulers, such as SGE and PBS • Adaptable for local execution and ssh execution

  8. Example of Job Submission Actors Job Submission Workflow. By Norbert Podhorszki from UC Davis. In SDM Project Funded by the DOE SciDac Award No. DE-FC02-07ER25811.

  9. Grid Actors • Actors: Grid Authentication, Globus Job, Grid Proxy, GridFTP, … • Support both Pre-WS and WS Globus Resource Invocation
