Grid Checkpointing Architecture – prototype

1. When we achieve the final version of definition of the GCA, we plan to begin the work on providing prototype implementation of that architecture (but it is not planned to be done within the period of time encompassed by Roadmap
2. The most probable development environment:
   • Globus Toolkit 4.0.1
   • Alternatively some other WSRF-based tools

GCA versus GridCPR

1. GCA is about utilizing a large variety of existing and future checkpointing packages within the Grid environment.
2. GridCPR defines API and a set of rules that programmers have to adhere to in order to make the new written application checkpointable in the Grid environment. The assumption is that the checkpointing functionality is embedded into the application on the development stage.
