Flexible Fork-Join Networks

Tuesday, June 17, 2014

Ramtin Pedarsani

Host: Prof. Tara Javidi

We consider a general flexible fork-join processing network, in which jobs are modeled as directed acyclic graphs with nodes representing tasks, and edges representing precedence constraints among tasks. Both servers and tasks are flexible in the sense that each task can be processed by several servers, which in turn can serve multiple task types. The system model is motivated by the problem of efficient scheduling of both sequential and parallel tasks in a flexible processing environment, which arises in many application areas such as data centers. A major challenge in designing efficient scheduling policies is the lack of reliable estimates of system parameters such as arrival and/or service rates. We call a policy robust if it does not depend on system parameters such as arrival and service rates. In this talk, we propose a provably throughput-optimal robust scheduling policy for the flexible fork-join network model.
