Optimal Pricing in a Single Server System
ACM Transactions on Modeling and Performance Evaluation of Computing Systems (TOMPECS), Volume 8, Issue 4Article No.: 12, Pages 1–32https://doi.org/10.1145/3607252We study optimal pricing in a single server queue when the customers valuation of service depends on their waiting time. In particular, we consider a very general model, where the customer valuations are random and are sampled from a distribution that ...

Delay and Price Differentiation in Cloud Computing: A Service Model, Supporting Architectures, and Performance
ACM Transactions on Modeling and Performance Evaluation of Computing Systems (TOMPECS), Volume 8, Issue 3Article No.: 6, Pages 1–40https://doi.org/10.1145/3592852Many cloud service providers (CSPs) offer an on-demand service with a small delay. Motivated by the reality of cloud ecosystems, we study non-interruptible services and consider a differentiated service model to complement the existing market by offering ...

Trading Throughput for Freshness: Freshness-aware Traffic Engineering and In-Network Freshness Control
ACM Transactions on Modeling and Performance Evaluation of Computing Systems (TOMPECS), Volume 8, Issue 1-2Article No.: 4, Pages 1–26https://doi.org/10.1145/3576919With the advent of the Internet of Things (IoT), applications are becoming increasingly dependent on networks to not only transmit content at high throughput but also deliver it when it is fresh, i.e., synchronized between source and destination. Existing ...

A Framework for Allocating Server Time to Spot and On-Demand Services in Cloud Computing
ACM Transactions on Modeling and Performance Evaluation of Computing Systems (TOMPECS), Volume 4, Issue 4Article No.: 20, Pages 1–31https://doi.org/10.1145/3366682Cloud computing delivers value to users by facilitating their access to servers at any time period needed. An approach is to provide both on-demand and spot services on shared servers. The former allows users to access servers on demand at a fixed price ...

Mean Field Games in Nudge Systems for Societal Networks
ACM Transactions on Modeling and Performance Evaluation of Computing Systems (TOMPECS), Volume 3, Issue 4Article No.: 15, Pages 1–31https://doi.org/10.1145/3232076We consider the general problem of resource sharing in societal networks, consisting of interconnected communication, transportation, energy, and other networks important to the functioning of society. Participants in such network need to take decisions ...

Scheduling Storms and Streams in the Cloud
ACM Transactions on Modeling and Performance Evaluation of Computing Systems (TOMPECS), Volume 1, Issue 4Article No.: 14, Pages 1–28https://doi.org/10.1145/2904080Motivated by emerging big streaming data processing paradigms (e.g., Twitter Storm, Streaming MapReduce), we investigate the problem of scheduling graphs over a large cluster of servers. Each graph is a job, where nodes represent compute tasks and edges ...
