Transform Method for Stochastic Processing and Matching Networks
Sushil Mahavir Varma, Prakirt Jhunjhunwala, Daniela Hurtado-Lange +1
Modern service systems, ranging from cloud data centers and ride-hailing platforms to healthcare facilities, operate at massive scales where it is important to handle congestion. Q…
Markov Modulated JSQ in Heavy Traffic Via the Poisson Equation
Daniela Hurtado-Lange, Izzy Grosof
In parallel-server systems with a single stream of arrivals (a.k.a. load balancing), Join-the-Shortest-Queue (JSQ) is a popular routing algorithm. There is extensive literature stu…
Outperforming Multiserver SRPT at All Loads
Izzy Grosof, Daniela Hurtado-Lange
A well-designed scheduling policy can unlock significant performance improvements with no additional resources. Multiserver SRPT (SRPT-k) is known to achieve asymptotically optimal…
Exponential Tail Bounds on Queues: A Confluence of Non-Asymptotic Heavy Traffic and Large Deviations
Prakirt Raj Jhunjhunwala, Daniela Hurtado-Lange, Siva Theja Maguluri
In general, obtaining the exact steady-state distribution of queue lengths is not feasible. Therefore, we establish bounds for the tail probabilities of queue lengths. Specifically…
Load balancing system under Join the Shortest Queue: Many-Server-Heavy-Traffic Asymptotics
Daniela Hurtado-Lange, Siva Theja Maguluri
We study the load balancing system operating under Join the Shortest Queue (JSQ) in the many-server heavy-traffic regime. If is the number of servers, we let the difference bet…
Throughput and Delay Optimality of Power-of-d Choices in Inhomogeneous Load Balancing Systems
Daniela Hurtado-Lange, Siva Theja Maguluri
It is well-known that the power-of-d choices routing algorithm maximizes throughput and is heavy-traffic optimal in load balancing systems with homogeneous servers. However, if the…
Logarithmic Heavy Traffic Error Bounds in Generalized Switch and Load Balancing Systems
Daniela Hurtado-Lange, Sushil Mahavir Varma, Siva Theja Maguluri
Motivated by application in wireless networks, cloud computing, data centers etc, Stochastic Processing Networks have been studied in the literature under various asymptotic regime…
Heavy-Traffic Analysis of Queueing Systems with no Complete Resource Pooling
D. Hurtado-Lange, S. T. Maguluri
We study the heavy-traffic limit of the generalized switch operating under MaxWeight, without assuming that the CRP condition is satisfied and allowing for correlated arrivals. The…
