Our view of the Grid

Our view of the Grid

Our view of the Grid

• Environment that is:

• Parallel
• Grid is built up from parallel machines
• Dynamic
• Resource allocation may change dynamically
• Distributed
• Resources are distributed over a network
• Resources are in different administration domains

• Need for a new programming technique

• Parallel self-adaptable distributed components

Related works

• Parallel and distributed components / objects exist

• Example: GridCCM, PARDIS

• Self-adaptable components exist

• Example: ACEEL, DART

• But no parallel and self-adaptable distributed component

Principles of parallel components

• Encapsulation of a parallel code

• Collaboration of several communicating processes

• Goal: allow to easily couple parallel codes
