Mobile Desktop Grid (MDG) uses open source technologies and mainly on Java platform that can run on any operating systems. It requires only small hardware requirement as small as any hand held devices that support JAVA (J2SE). Resource contributors around the world need to register their cluster machines joining with MDG Server. The resource users are able to utilize those identified pool resources after registration. Resource contributors are from individual, organization, education institutional and laboratory lab who would like to share out their machine clusters for public use. Whereas resource users are public individuals, university students, organization personnel, lab researchers and officers who require to perform exhaustive computational jobs.

The capabilities of single organization or individual investing in machines assets and computational powers are limited in growing and always constraint by financial budget. The boundary of single organization or individual that owns machines assets and computational powers can be opened up with the MDG solution. Problem of insufficient resources when addressing global issues have the answer from MDG solution. On top of enjoying unlimited computational resource, MDG solution enables resource user to obtain either homogeneous or heterogeneous cluster resources, different CPU processing speed, and various combination of cluster CPU-memory-network environments. Resource users can perform more unit-testing based on these variety environments to obtain more significant testing results in research. As the result, MDG solution is another researcher daily tool option to use in achieving research project mission and vision, such as global research collaboration modeling in against the pandemic threat of Avian flu and other emerging infectious diseases such as virus SARS and A-H1N1.

MDG solution is an one-stop solution to obtain worldwide cluster resource for computational use. With MDG solution, world wide physicist, biologist, chemist, laboratory assistant and computer scientist are able to complete their exhaustive computational jobs in a shorter period. MDG solution is a solution to aid researchers addressing global issues. Users can be from non-grid or non-cluster awareness group of people but still they are able to utilize cluster resources with our invented solution. We glad to announce that MDG proudly incorporated with at least 15 freely open source middleware. It shows the capability and reality of the rendezvous of web services technologies, grid computing resources exploration and OpenMessagingSystem protocol in today open source technologies.

MDG offers a new research studying platform for computer science postgraduate student, such as adopting others intra-communication protocol, embedding meta-scheduler for more wider clustered resources recruitment and computational execution, and intelligent responsive to computational interruption process. There are couples of research improvement and hybrid-with-in-progress study can be done in MDG model design perspective, such as adopting others intra-communication protocol, embedding meta-scheduler for more wider clustered resources recruitment and computational execution, and intelligent responsive to computational interruption process.

We lead to change tomorrow with MDG solution. Public who would like to experience freely parallel and distributed processing implementation model, MDG solution is the answer. Researchers who are addressing global issue in labs have MDG solution as their daily option tools. Let's MDG facilitate you to help the Bottom Billions with your project.

Lets MDG team change tomorrow together with you!
