AppPot is a way to implement generic application deployment on a computational Grid, and especially to enable users to provide their own software to the computing cluster.

AppPot uses User Mode Linux to provide users with a development and running environment they have full control over. User Mode Linux provides a virtualized environment in which users can build and run their own computational applications. AppPot? augments this with scripts that can take a copy of the UserModeLinux? system image and submit it as a regular computational job using the ARC middleware.

An overview of AppPot and its purpose can be found in these slides presented at the EGI Technical Forum 2011.

The most complete information on the AppPot design, motivation, and architecture is the arXiv 1203.1466 paper.
