An Object-Oriented Job Execution Environment

This is a project for developing a distributed job execution environment for highly iterative jobs. An iterative job is one where the same binary code is run hundreds of times with incremental changes in the input values for each run. An execution environment is a set of resources on a computing platform that can be made available to run the job and hold the output until it is collected. The goal is to design a complete, object-oriented scheduling system that will run a variety of jobs with minimal changes. Areas of code that are unique to one specific type of job are decoupled from the rest. The system allows for fine-grained job control, timely status notification and dynamic registration and deregistration of execution platforms depending on resources available. Several objectedoriented technologies are employed: Java, CORBA, UML, and software design patterns. The environment has been tested using a CFD code, INS2D. Key words: job scheduling, object-orientation, Java, and CORBA.
