Summary and Team Members

Goal: Create a node reservation management system for Boeing's Linux clusters.

Platform: RedHat Linux 9 - Enterprise Edition

Technology: Ruby, GTK2, XML RPC via DRB

Project Team:

• David Kohrn (Sponsor)
• Joe Van Dyk (Liaison)
• Roshanak Roshandel (Advisor)
• Reza Tehrani (Student)
• Edington Watt (Student)
• Karl Wiegand (Student)

Project Motivation

Existing situation:

• Small number of mainframes
• Informal method of scheduling
• No record of past usage

Desired situation:

• Large number of clustered Linux nodes
• Computerized scheduling system
• History of past reservations and usage patterns

Development Methodology

• FreeBSD; SuSE Linux, then Fedora Core
• Customized, iterative SDLC
• Desired iteration length: 4-5 weeks
• Weekly in-person meetings
• Work divided on "first-come, first-write" basis
• Testing divided on "first-finish, first-test" basis
• Informal code reviews on previously identified tasks

Development Life Cycle

Early Evolution

Project Preparation:

• Learn language/technology
• Set up development environment
• Style guides and methodology documents
• September - October (4 weeks)

Iteration 1:

• Mostly cosmetic
• Book reservation on a node
• Requirements on 11/1/2005 (last touch)
• November - January (8 weeks)

Early Version

Intermediate Evolution

Iteration 2:

• Persistent, global reservations
• Requirements on 1/25/2006 (last touch)
• January - February (3 weeks)

Iteration 3:

• Reservation enforcement and permissions
• Requirements on 2/16/2006 (last touch)
• February - March (5 weeks)

Intermediate Version

Final Evolution

Iteration 4:

• Graphical view of reservations
• Requirements on 3/29/2006 (last touch)
• March - April (4 weeks)

Project Closeout:

• Documentation, bug fixes, and presentation
• May - June (4 weeks)

Final Version
