Project Info

This project is a Web Service based computational grid infrastructure
written in Java. Once setup, it allows a user to submit job(s) to the
grid to be scheduled for execution on the grid nodes

If there is enough interest in this project, I will continue its development
Things to do:

fix CVS repositories
fix 1:1 service to database mapping
support databases other than mysql
create a "real" webpage
create documentation
etc, etc, etc...

Technologies / packages used

Java
Java Web Services
JAX-RPC
JAXB
SAAJ
Hyperic Sigar

Components

Job Host - runs submitted executables
Resource Manager - registry of job hosts
Job Scheduler - schedules jobs on registered job hosts
Job Client - command-line interface to grid services

Notes / Problems:
-----------------

- Most services are configurable using a config file or through the command
line. The first time a service is installed, it should be configured through
the command-line, which will generate a configuration file for you.

- Java network security settings might need to be tweaked. I don't remember
the process required in order to do this, but I remember having to edit a
configuration file in the J2SE "\lib\security" directory. Only necessary if
strange error messages are being seen when attempting to use the Web services.

- The database design was poorly done. All of the services should be able to
point to a single database, but can't in the current version. I didn't include
columns to uniquely identify what data each service owns, so there is a 1 to 1
relationship between a database and a service. This could easily be fixed, and
wouldn't require large changes to the code. This would be localized to the
Sql.java files associated with each service, and updating the database schema.

- The files needed to distribute the packages are located in the 'jwsgrid' directory.
Everything but the 'src' subdirectory should be included on machines that will
run a service.
