Multiparadigm Model Oriented to Development of Grid Systems

摘要

Multiparadigm approach integrates programming language paradigms. We propose Holoparadigm (Holo) as a multiparadigm model oriented to development of grid systems. Holo uses a logic blackboard (called history) to implement a coordination mechanism. The programs are organized in levels using abstract entities called beings. First, we describe the principal concepts of the Holoparadigm. After, the principles of a language based on the Holoparadigm are presented. Besides, we propose the Grid Holo (GHolo), a platform to support the multi-domain heterogeneous distributed computing of programs developed in Holo. GHolo is based on object mobility and blackboards. This distributed model can be fully implemented on Java platform.
