biology.sdsc.edu What is a Scientific Workflow?  Combination of  data integration, analysis, and visualization steps  larger, automated "scientific process"  Mission of scientific workflow systems  Promote “scientific discovery” by providing tools and methods to generate scientific workflows  Create an extensible and customizable graphical user interface for scientists from different scientific domains  Support computational experiment creation, execution, sharing, reuse and provenance  Design frameworks which define efficient ways to connect to the existing data and integrate heterogeneous data from multiple resources  Make technology useful through user’s monitor!!!

biology.sdsc.edu Summary  Kepler is good at:  Integrating data, programs, and computing resources  Capturing your ideas and realizing them  Supporting computational experiment creation, execution, sharing, and reuse  Quickly prototyping scientific workflows  Building streamlining applications  Visual programming language  Don’t write your application, “draw”/compose it  Cipres-Kepler package can be used to build scientific workflows for phylogenetic data analyses

biology.sdsc.edu Future Work  Cipres-Kepler can help you  There is (always) a lot more to work on:  More actors for phylogeny analyses  Automatically generating actors based on CORBA services  Database (TreeBase) support to store large amounts of data  More computing power for large dataset processing  Need your collaboration:  Sharing experiences  Teaching each other the domain knowledge  Locating a specific problem and solving it
