Associated Problems

  • Centralized matchmaking:

    • Low scalability: efficient only in a certain range of

    • population size

    • Low robustness:

    • - when matchmaker leaves the network/ goes down

    • due to connection failure or overloaded with

    • information

  • Peer to peer:

    • Low throughput: when there is no interaction between

    • nodes’ neighborhoods

Motivation

Designing an adaptive and robust mechanism that enables the network to change its internal matchmaking approach from peer to peer to a more centralized form or vice versa whenever it is required.

Adaptive Approach

  • For instance,

  • when population size of the system grows beyond the

  • capacity of single matchmaker, then adapt to more

  • localized model i.e. partition the system into

  • segment each segment having its own matchmaker

  • when population size of the system shrinks, then

  • adapt to more centralized model i.e. combine the

  • segments to reduce the number of matchmakers

Adaptation Model

Node Attributes

  • System Level:

    • more matchmakers – when system grows

    • less matchmakers – when system shrinks

  • Node Level:

    • producer/consumer => matchmaker

    • matchmaker => producer/consumer

Consumer attributes =>{ resource request, job manager, job queue }Producer attributes =>{ resource report , resource manager,

resource context }

Matchmaker attributes => { resource list, job list, matchmaking function machmaker list, load balancer }

Adaptation Issues

  • how, when and who decides to reconfigure the

  • system?

  • how an individual node becomes a matchmaker?

  • how to partition the system into segments to

  • balance between jobs and resources?
