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…
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…
The Case for Replication-Aware Memory-Error Protection in Disaggregated Memory
Haris Volos
Disaggregated memory leverages recent technology advances in high-density, byte-addressable non-volatile memory and high-performance interconnects to provide a large memory pool sh…
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…
MODC: Resilience for disaggregated memory architectures using task-based programming
Kimberly Keeton, Sharad Singhal, Haris Volos +9
Disaggregated memory architectures provide benefits to applications beyond traditional scale out environments, such as independent scaling of compute and memory resources. They als…
Sparkle: Optimizing Spark for Large Memory Machines and Analytics
Mijung Kim, Jun Li, Haris Volos +7
Spark is an in-memory analytics platform that targets commodity server environments today. It relies on the Hadoop Distributed File System (HDFS) to persist intermediate checkpoint…
