Free to join for developers who support the Free Software Foundation cause. This is my research project from 2003, which I recently updated with acceleration- and console changes (Surround Sound, Doppler Effects, Device Updates, Physics) in a long weekend but project should be considered abandoned. Additionally, the Performer libraries have been abandoned by Silicon Graphics. Minor setup- and make reconfiguration bugs, no changes planned. The Command Centre is a Simulation Programming Framework for advanced Command and Control Simulators on Linux/Windows using C/C++ and Java. The Framework integrates with Leading Tools like Visual Paradigm (UML), Net Beans 7.0 (Java), and Code Warrior (C/C++). The codebase supports building Heterogenous Command and Control Consoles and Accelerated User Attached Audiovisuals. The Command Centre Real Time Simulation Framework (under RT Linux) allows designers to build Fast Prototyped Consoles for advanced Simulations running on Local Area Networks.

The Genomic Diversity and Phenotype Connection (GDPC) written in JAVA uses web services to make XML formatted data publicly available. The GDPC Browser (front-end GUI) can access these services, and other applications can use the API.

In Green Cloud here is a central global server which does the work of global database management along with providing complex analysis services for the users (farmers, scientists) through the client machines and the public access web portal. The existing agricultural databases throughout the world can also be used for inference purposes and their data may also be updated by our server. The meteorological servers can be accessed for climate data.This server-client architecture mandatory in present and even near-future circumstances as the client machine has to be low-power and low-cost for the feasibility of the system in Indian context. Therefore, the complex analysis (Expert system analysis in accordance with world-wide data) has to be done on server. The environment data is collected via sensors is uploaded to the website
