Truthful Online Scheduling of Cloud Workloads under Uncertainty
Moshe Babaioff, Ronny Lempel, Brendan Lucier, Ishai Menache, and Aleksandrs Slivkins, Sam Chiu-Wai Wong

TL;DR
This paper proposes a truthful online scheduling framework for cloud workloads with uncertain, strategic job submissions, using pricing and eviction mechanisms to optimize social welfare under various submission models.
Contribution
It introduces a novel framework that reduces scheduling under uncertainty to a relaxed problem, enabling truthful, competitive mechanisms for both adversarial and stochastic inputs.
Findings
Logarithmic competitive ratio for adversarial submissions
Constant competitive ratio for stochastic submissions
Mechanisms incentivize truthful reporting of private information
Abstract
Cloud computing customers often submit repeating jobs and computation pipelines on \emph{approximately} regular schedules, with arrival and running times that exhibit variance. This pattern, typical of training tasks in machine learning, allows customers to partially predict future job requirements. We develop a model of cloud computing platforms that receive statements of work (SoWs) in an online fashion. The SoWs describe future jobs whose arrival times and durations are probabilistic, and whose utility to the submitting agents declines with completion time. The arrival and duration distributions, as well as the utility functions, are considered private customer information and are reported by strategic agents to a scheduler that is optimizing for social welfare. We design pricing, scheduling, and eviction mechanisms that incentivize truthful reporting of SoWs. An important…
