1. Pipeline Execution Environment Laboratory of NeuroImaging UCLA

2. What is the Pipeline? It is a data flow execution environment It is useful for… –Any task where you can draw the steps in a flowchart –Any task where you need to write instructions for someone We use it for neuroimaging analysis –To be extended in the near future to bioinformatics

3. Pipeline features –Modular, extensible architecture Components Events Modules- user defined –High grade encrypted communications –Automatic & transparent resource management –Shell script output –Feature rich GUI

4. Pipeline features (cont.) Distributed computing –Cluster computing Local clusters (e.g PVM) –Intranet grid computing Grid engine –Internet/overlay grid computing In development

5. A live example (bear with me while I try this)

6. Roadmap 6/2005 –Beta to be released 12/2005 –Fault tolerance –Overlay grid implementation 6/2006 –ITK/VTK integration –SCIRun Integration –Provenance Data validation Information recovery

7. Roadmap (cont.) Ongoing –Ontologies –Self learning system Automated analysis –Natural language interface
