Commodity Grid (CoG) Kits allow Grid users, Grid application developers, and Grid administrators to use, program, and administer Grids from a higher-level framework. The Java and Python CoG Kits are good examples. These kits allow for easy and rapid Grid application development. They encourage collaborative code reuse and avoid the duplication of effort among problem solving environments, science portals, Grid middleware, and collaboratory pilots.

It is an often overlooked fact that CoG Kits are also used within the Globus Toolkit, and provide important functionality. The Java CoG Kit, for example provided the implementation of Java-based GSI, gridFTP, myProxy, GRAM client implementations. Today the Java CoG Kit provides additional functionality beyond that of the Globus toolkit. Among this functionality you will find the concept of Grid abstractions and providers, workflows, and support for portal developers.

Call for Collaboration

Our close collaborators and sponsors have the benefit of obtaining specialized versions and receive priority consultation. If you would like to sponsor us or work with us in a more direct fashion as part of your projects, please contact We have expertise in Grid workflows, middleware, portals, gateways, applications, and naturally in the Java and Python CoG Kits. We have PI status in NSF and DOE and can also be part of SBIRs or STTRs. Subcontracts are possible.
