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)
