Relational Grid Monitoring Architecture (R-GMA)

Title: Relational Grid Monitoring Architecture (R-GMA)

Research Question: How can a relational database model be used to create a more efficient and flexible information and monitoring system for computer grids?

Methodology: The researchers developed R-GMA, a relational implementation of the Grid Monitoring Architecture (GMA) from the Global Grid Forum. They used servlet technology and web services to build the system, aiming to create a more powerful and adaptable system than previous versions.

Results: The researchers found that using the relational model allowed for the formulation of powerful queries over the data. They also developed five different Producer types: DataBaseProducer, StreamProducer, ResilientProducer, Latest-Producer, and CanonicalProducer. Each of these types had different characteristics, allowing for more flexibility in data publication and consumption.

Implications: The R-GMA system has been deployed in various testbeds and has shown promising results. The system's ability to provide a global view of information and its flexibility in querying and producing data make it a promising tool for grid information and monitoring. The use of the relational model also allows for the creation of more complex and powerful queries, further enhancing the system's capabilities.
