Title:   Progressive Messages: Tracking Message Progress Through Events

Abstract:
  High-end computing systems tend to be loosely coupled because
  of the performance, price, scalability and reliability
  advantages of dense, distributed systems. Current computing
  tools however are very rigid and do not cope well with dynamic
  or unplanned changes, such as a crash in part of the system.
  Such is particularly true of communications tools or computing
  frameworks that rely on messages over a network. Users often
  must `design around' these inflexible structures to handle
  unplanned incidents or to develop fault tolerance.

  This talk will present the Progressive Messages model of
  communication, which addresses the above concerns by providing
  a scheme that alerts the user whenever an `event' occurs within
  the network. Here an event is triggered whenever a message
  enters a new state of progress, such as submission, arrival or
  failure. Progressive Messages provides the primitives the user
  needs to develop application-specific solutions.


Biography:
  Christopher C. Aycock received his BS and MS from Penn State
  and is currently a PhD student at Oxford. He is a visiting
  fellow at ANU under Richard Brent. His interest is in software
  tools that make high-performance computing more accessible.
