Model Integrated Computing (MIC)
Model-Integrated Computing (MIC) is a model-based concept for software development that facilitates to synthesis the application programs into models. It employs domain-specific models to represent the software, its environment, and their relationship and well-suited for the rapid design of complex computer-based systems. MIC concept is used to transform one DSML into another DSML.
Several tools available for metamodeling such as AToM3, MetaEdit+, DOME, Generic Model-ing Environment (GME) , and KOGGE. GME is a graphical and meta-programmable tool that is based on the principles of MIC and it automates the creation of domain-specific models. GME provides a universal design environment that can be configured for a wide range of domains.

Grid computing
Grid computing is a form of distributed computing in which an organization (business, university, etc.) uses its existing computers (desktop and/or cluster nodes) to handle its own long-running computational tasks. This differs from volunteer computing in several ways:
- The computing resources can be trusted; i.e. one can assume that the PCs don't return results that are intentionally wrong, and that they don't falsify credit. Hence there is typically no need for replication.
- There is no need for screensaver graphics; in fact it may be desirable to have the computation be completely invisible and out of the control of the PC user.
- Client deployment is typically automated.
