2 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

3 Goals FY06 1. UABgrid Computing Pilot Project involving ITAC and several campus HPC user groups Demonstrate using 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.

4 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).

5 Summary of Presentations Internet2 Member Meeting UAB NMI Testbed Program: Integrated Directory Services, Weblogin, and Grid Computing [September 2004] Middleware-Enabled Tools for Virtual Organizations, Jill Gemmill and John-Paul Robinson [May 2005] EDUCAUSE Middleware Workshop UABgrid: A Foundation for Collaboration and Computation Jill Gemmill [June 2005]

6 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

7 UAB Authoritative Directory

8 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

9 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

10 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

11 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

16 VO Workspace of the Future Identity and Attributes shared across applications and organizations Access Control to all shared resources based on rules, e.g. membership Flexible and secure Creating one large, seamless data set from many distributed sets, with secure access Scalability possible (alternatives to one account per user per system) Collaboration tools Shared file space Video/Voice conferencing Any tool you need
