Mission Provide leadership for UAB research community while interfacing important initiatives to appropriate information technologies that enable success, and Provide a test-bed for advanced technologies and a mechanism for migration of selected technologies into production, core IT services

Goals FY06 1. UABgrid Computing Pilot Project involving ITAC and several campus HPC user groups Demonstrate using http://uabgrid.uab.edu as an environment for running applications, such as BLAST Measure and compare computing performance UABgrid versus batch processing for several applications using a matrix including characteristics of application, infrastructure, and ease-of-use. 2. Collaborative Technologies Pilot Project Establish a pilot Shibboleth deployment for inter-institutional user authentication and authorization of access to common workspace supporting calendar, document sharing, data sharing, and communications technologies to desktop.

Middleware Invisible services, between application and network, allowing people to work together without being limited by the boundaries of their computing and local administrative environments Virtual Organization Collaborations, research partnerships, communities of users who communicate regularly and share data, resources, and services. Yesterday s lab is today s Virtual Organization (VO).

Integrated Directory Services Where is UAB Today? Single authoritative identity management directory Single management point for Creating BlazerID password resets user account creation/deactivation Implemented latest NMI schema recommendations (Groups, H.350, eduperson, eduorg, LDAP Recipe) Even more applications using LDAP

What is the Grid? Emerging standards for integration of different computing environments into what appears as a single computing environment Standards bodies involved are: Global Grid Forum OASIS; W3 consortium; Distributed Mgt. Task Force; Web Services Interoperability Org.; Internet2 and Liberty Alliance

Why is Grid Computing Important? 20 th Century Research Model: a single institution concerned about information held internally and accessed by its own people 21 st Century Model: Virtual Organizations form dynamically across institutional boundaries to access and share distributed information and resources (eg: cabig and National E-Network for Primary Care Research see NIH Roadmap) Opportunity exists to leverage home institutions authentication and attribute storage (directory) systems

What is a campus grid UABgrid today Gain access using BlazerID and password - authentication Job submission via web interface Authorization decisions made based on institutional attributes to provide access to a set of resources (compute, storage, and data) Grid Security is based on security provided by digital certificates; UABgrid allows user key management or makes that transparent http://uabgrid.uab.edu/

Example User-Friendly Interface GridBLAST For jobs run repeatedly, it is possible to build a userfriendly interface Example: BLAST Access using BlazerID and password Queries and Results easily uploaded & downloaded Web UI can be hosted on your server Web UI can be written in any development language
