Discussion

Goals of Component Architecture

• Support different implementations of collective operations
  • XCCL, UCG, SHARP, open-source, proprietary
• Ability to support different implementations of collective algorithms
• Abstract p2p communication, memory management, topology, and service libraries

Framework: Framework is a coarse-grained abstraction of the functionality. Enables building of functionality combining different implementations

• What should be a framework? Collectives, p2p communication, services?

Component: A component is a fine-grained abstraction of the functionality.

• What should be a component? An instance of collective implementation, p2p communication, multicast communication?

Component or Framework?

• p2p abstraction
• memory registration
• caching (rcache)
• topology management
• UCS (services)

Component architecture discussion to be continued
