How long can you sleep? Idle Time System Inefficiencies and Opportunities
Georgia Antoniou, Haris Volos, Jawad Haj Yahya +1
This work introduces a model-based framework that reveals the idle opportunity of modern servers running latency-critical applications. Specifically, three queuing models, M/M/1, c…
AgilePkgC: An Agile System Idle State Architecture for Energy Proportional Datacenter Servers
Georgia Antoniou, Haris Volos, Davide B. Bartolini +3
This paper presents the design of AgilePkgC (APC): a new C-state architecture that improves the energy proportionality of servers that operate at low utilization while running micr…
AgileWatts: An Energy-Efficient CPU Core Idle-State Architecture for Latency-Sensitive Server Applications
Jawad Haj Yahya, Haris Volos, Davide B. Bartolini +9
User-facing applications running in modern datacenters exhibit irregular request patterns and are implemented using a multitude of services with tight latency requirements. These c…
Taming Performance Variability caused by Client-Side Hardware Configuration
Georgia Antoniou, Haris Volos, Yiannakis Sazeides
Many online services running in datacenters are implemented using a microservice software architecture characterized by strict latency requirements. Consequently, this popular soft…
