NA-MIC National Alliance for Medical Image Computing UCSD: Engineering Core 2 Portal and Grid Infrastructure

National Alliance for Medical Image Computing NAMIC Grid Infrastructure Leverage BIRN infrastructure development and deployment –Security Architecture –Data Grid –Computational Grid Resources –Portal –Grid Deployment

National Alliance for Medical Image Computing Overview of the BIRN Roadmap Deliver and maintain a robust and scalable PRODUCTION Grid for the collaborative sharing, analysis and interrogation of biomedical data Provide integrated solutions for core domain science research Provide a consistent and scalable delivery mechanism Be a vehicle for bringing biomedical sciences and scientists to the Grid Be the biomedical applications driver for the global Grid community “Enforce the AEIOU’s – Accessibility, Extensibility, Interoperability, Openness, Usability, Scalability”

National Alliance for Medical Image Computing Current Grid Infrastructure

National Alliance for Medical Image Computing BIRN Core Software Infrastructure BIRN builds on evolving community standards for middleware Adds new capabilities required by projects Does System Integration of domain- specific tools building a distributed infrastructure Utilizes commodity hardware and stable networks for baseline connectivity

National Alliance for Medical Image Computing Security Infrastructure Security based on Grid standards (i.e. GSI - Grid Security Infrastructure) –Each user is assigned their own private credentials by the BIRN Certificate Authority Users don’t see complexity of infrastructure - single sign-on via a secure username and password –Certificate Authority –Escrow of user credentials –Management of proxy credentials Authentication service available to any application or service

National Alliance for Medical Image Computing Single Sign-On via Authentication Service Authentication service available to all applications Multiple implementations available –e.g. Java, PERL Authentication Service Certificate Authority Proxy Management Delegate Proxy Fetch New Proxy Validate Proxy

National Alliance for Medical Image Computing Authentication for Applications Single sign-on authentication can be accomplished from non-Grid tools Initiates Portal session to handle common services Authentication Service Authenticate User Issue Proxy Certificate Authority Proxy Management 1 2 3

National Alliance for Medical Image Computing BIRN Data Grid Defines a Distributed Data Handling System Integrates Storage Resources in the BIRN network Provides a Uniform Interface to Users Users interact with data in a logical file space (i.e. location of files is hidden from the user)

National Alliance for Medical Image Computing Sharing data using BIRN Data Access Control & Auditing Metadata Search Data Management The BIRN Portal and Data Grid provides secure and audited access to NAMIC data from Core 3 sites with a Single Login from any Internet capable location.

National Alliance for Medical Image Computing Data Grid Access A coordinated suite of tools and interfaces to are available that interact with the BIRN Data Grid –Programmatic interfaces - e.g. JARGON Java API –Command Line access –Graphical User Interface Java Data Grid Browser (local client) Web Data Grid Browser (remote server) –Contributed tools - e.g. SRBwrap from JHU Allows users to tailor access to the data grid based on their requirements

National Alliance for Medical Image Computing Grid Computing Infrastructure Provide an open resource for grid computing –Production computational grid –Research and development grid Provisioning middleware and services for large scale grid computation –Authentication –Scheduling –resource discovery –Resource management Needed for Grid Workflows

National Alliance for Medical Image Computing Grid Based Workflows Authentication, resource discovery and scheduling! Currently there are many standards for the description of workflows. Grid workflow environment must be open and able to interact with multiple workflow tools and languages. Collaborating with grid community (e.g. Telescience, GEON, UK e- Science) –Definition of grid-based workflow description languages –Development of grid based workflow execution environment

National Alliance for Medical Image Computing Portal Job Management Portal based user interfaces Job management functions provide detailed job information for execution on remote resource

National Alliance for Medical Image Computing BIRN Portal Application environment that provides transparent and pervasive access to the BIRN infrastructure (i.e. tools, applications, resources) with a Single Login from any Internet capable location Provides simple, intuitive access to distributed resources for data storage, distributed computation, and visualization Support for dynamic collaborative projects such as NAMIC Built on standard Portal framework

National Alliance for Medical Image Computing BIRN Portal Framework Future -> GridSphere portal framework –Based on a portlet model: gives developers an open way of creating and adding new elements to the portal –JSR-168 compatible: Java portlet standard that enables interoperability between Portlets and Portals –Open Source –Community development across many Grid based projects Distributed Portal development and deployment

National Alliance for Medical Image Computing Allow continual improvement of the BIRN software infrastructure in terms of performance, robustness and interoperability, Support use of latest development efforts without disruption to development effort or production operation Separately instantiated development, staging and production environments provide robust, yet flexible areas for developing, testing, and deploying BIRN system software Twice yearly, in April and October, a complete production integrated BIRN software stack is released (and deployed on the BIRN physical hardware infrastructure) Development Environment

National Alliance for Medical Image Computing Grid System Deployment BIRN specific extensions to Rocks grid management software, means automated, repeatable deployment of any version of the BIRN system We’ve created BIRN “rolls” that integrate –BIRN domain tools (e.g. 3DSlicer, LONI Pipeline, FreeSurfer) –Database (Oracle) and Data Grid Configuration Rocks, with BIRN extensions, includes automated deployment mechanism for –Middleware (Security, Computational, Data) –Data mediation/integration –Application codes –Portal
