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…
Analyzing a Two-Tier Disaggregated Memory Protection Scheme Based on Memory Replication
Haris Volos, Yiannakis Sazeides
As memory technologies continue to shrink and memory error rates increase, the demand for stronger reliability becomes increasingly critical. Fine-grain memory replication has emer…
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…
