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 VirtualOrganization

“Invisible” services, between application and network, allowing people to work together without being limited by the boundaries of their computing and local administrative environments

Collaborations, research partnerships, communities of users who communicate regularly and share data, resources, and services. Yesterday’s “lab” is today’s Virtual Organization (VO).


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]


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


UAB Authoritative Directory


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?

20th Century Research Model: a single institution concerned about information held internally and accessed by its own people

21st 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/


For jobs run repeatedly, it is possible to build a user-friendly 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
