Load Balancing in the Non-Degenerate Slowdown Regime
We analyse Join-the-Shortest-Queue in a contemporary scaling regime known as the Non-Degenerate Slowdown regime. Join-the-Shortest-Queue (JSQ) is a classical load balancing policy for queueing systems with multiple parallel servers. Parallel server queueing systems are regularly analysed and dimensioned by diffusion approximations achieved in the Halfin-Whitt scaling regime. However, when jobs ...
متن کاملA diffusion regime with nondegenerate slowdown
We study a diffusion regime, earlier considered by Gurvich, Mandelbaum, Shaikhet and Whitt in the case of the M/M/N queue, that is, in a sense that we make precise, a midpoint between two well-known heavy traffic diffusion regimes, the conventional and the quality and efficiency driven regimes. Unlike the other two, this regime, that we call the non-degenerate slowdown regime, enjoys the proper...
متن کاملScheduling Parallel Servers in the Nondegenerate Slowdown Diffusion Regime: Asymptotic Optimality Results1 by Rami Atar
We consider the problem of minimizing queue-length costs in a system with heterogenous parallel servers, operating in a many-server heavy-traffic regime with nondegenerate slowdown. This regime is distinct from the wellstudied heavy traffic diffusion regimes, namely the (single server) conventional regime and the (many-server) Halfin–Whitt regime. It has the distinguishing property that waiting...
متن کاملAsymptotically optimal interruptible service policies for scheduling jobs in a diffusion regime with nondegenerate slowdown
A parallel server system is considered, with I customer classes and many servers, operating at a heavy traffic diffusion regime where the queueing delay and service time are of the same order of magnitude. Denoting by X̂ and Q̂ the diffusion scale deviation of the headcount process from the quantity corresponding to the underlying fluid model and, respectively, the diffusion scale queue-length, w...
