Talk Anshul Gandhi: "Resource Management and Scheduling in Today’s Cloud"Talk Anshul Gandhi: "Resource Management and Scheduling in Today’s Cloud" – Title: Resource Management and Scheduling in Today’s Cloud
Abstract: The cloud computing landscape today is evolving quickly. New computing and deployment paradigms, like serverless computing and microservices architecture, are augmenting the classical VM-based cloud that we are all familiar with. In this new cloud, the basic question still remains "How do we efficiently utilize available resources to maintain low application latency". In this talk, I will discuss this evolving landscape briefly and then describe some recent works from our lab that address resource management and scheduling problems in the context. I will start by discussing ENSURE, our serverless scheduling solution that aims to maintain serverless function latency while minimizing the amount of resources needed. The specific challenges here are the diversity in serverless workload characteristics and the cold start penalty that non-warm containers incur when launched. I will then discuss our analytical and systems contributions in the context of colocating workload in the cloud with the goal of minimizing performance interference while maximing resource usage. I will end with a brief discussion of other projects in the cloud computing space we have looked at, including deploying Spark in an NDP environment, optimizing TensorFlow DNN training times in multi-GPU servers, and tuning the configuration of microservices architecture applications.
Bio: Anshul Gandhi is an Associate Professor in the Computer Science Department at Stony Brook University. He received his Ph.D. from Carnegie Mellon University in 2013 and then spent a year as a postdoc at the IBM T. J. Watson Research Center. His current research focuses on performance modeling in distributed systems, and is funded by an NSF Career award, an IBM Faculty award, and a Google Research award. His contributions to performance modeling were recently recognized by an ACM Sigmetrics Rising Star Award.

Séminaire Antoine Oustry: Polynomial optimization for parameterizing dynamical systemsSéminaire Antoine Oustry: Polynomial optimization for parameterizing dynamical systems – Polynomial optimization for parameterizing dynamical systems Abstract: We consider a polynomial dynamical system that depends on some tunable parameters. We raise the question of how to configure this system optimally, in terms of costs and stability. |

Seminar Bryce Ferguson: "Information and Influence: Overcoming and Exploiting Uncertainty in Congestion Games"Seminar Bryce Ferguson: "Information and Influence: Overcoming and Exploiting Uncertainty in Congestion Games" – Bryce Ferguson (https://web.ece.ucsb.edu/~blf/)
Title: Information and Influence: Overcoming and Exploiting Uncertainty in Congestion Games
Abstract: In large-scale, socio-technical systems (such as traffic networks, power grids, supply chains, etc.) the operating efficiency depends heavily on the actions of human users. It is well known that when users act in their own self-interest, system performance can be sub-optimal. Our capabilities in alleviating this inefficiency rely on our knowledge of user decision making and various system parameters. In this talk, I will present two settings where information affects our ability to influence system performance. In the first, we consider designing monetary incentives for players in a congestion game without exact knowledge of users’ price-sensitivity or path latency-characteristics; we provide a comparison of the effectiveness of different incentive types and quantify the value of different pieces of information. In the second, we consider a flipped paradigm, where the system operator has more information about system parameters than the users and can selectively reveal pertinent information. We show, in the context of Bayesian-congestion games, that signaling information to users has the opportunity to improve system performance but also the capability to make performance worse than if no information were shared at all. We then show the advantages of concurrently using monetary incentives and information signals by providing bounds on the benefit to system performance and methods to find optimal mechanisms of each type.
