Efficient Workload Colocation in Modern Data Centers

Despite the high costs of acquisition and maintenance of modern data centers, machine resource utilization is often low. Servers running online interactive services are over-provisioned to support peak load (which only occurs for a fraction of the time), d ...

Scalable Synchronization in Shared-Memory Systems: Extrapolating, Adapting, Tuning

Georgios Chatzopoulos

As hardware evolves, so do the needs of applications. To increase the performance of an application, there exist two well-known approaches. These are scaling up an application, using a larger multi-core platform, or scaling out, by distributing work to mul ...

dhSegment: A generic deep-learning approach for document segmentation

Frédéric Kaplan, Sofia Ares Oliveira, Benoît Laurent Auguste Seguin

In recent years there have been multiple successful attempts tackling document processing problems separately by designing task specific hand-tuned strategies. We argue that the diversity of historical document processing tasks prohibits to solve them one ...

Near-Memory Address Translation

Javier Picorel Obando

Virtual memory (VM) is a crucial abstraction in modern computer systems at any scale, from handheld devices to datacenters. VM provides programmers the illusion of an always sufficiently large and linear memory, making programming easier. Although the core ...

Near-Memory Address Translation

Babak Falsafi, Javier Picorel Obando, Dorde Jevdic

Memory and logic integration on the same chip is becoming increasingly cost effective, creating the opportunity to offload data-intensive functionality to processing units placed inside memory chips. The introduction of memory-side processing units (MPUs) ...

Axo: Tolerating Delay Faults in Real-Time Systems

Jean-Yves Le Boudec, Simon Bliudze, Wajeb Saab, Maaz Mashood Mohiuddin

We address delay faults: faults that cause a software component to take more time for completing an action than a given deadline. Such faults are particularly of interest in real- time mission-critical control applications that use general-purpose computin ...

Enabling efficient OS paging for main-memory OLTP databases

Anastasia Ailamaki, Radu Ioan Stoica

Even though main memory is becoming large enough to fit most OLTP databases, it may not always be the best option. OLTP workloads typically exhibit skewed access patterns where some records are hot (frequently accessed) but many records are cold (infrequen ...

Architectural Support for Coherent Architecturally Visible Storage in Instruction Set Extensions

Ties Jan Henderikus Kluter

When it comes to performance, embedded systems share many problems with their higher-end counterparts. The growing gap between top processor frequency and memory access speed, the memory wall, is one such problem. Driven, in part, by low energy consumption ...

PAI: A lightweight mechanism for single-node memory recovery in DSM servers

Babak Falsafi

Several recent studies identify the memory system as the most frequent source of hardware failures in commercial servers. Techniques to protect the memory system from failures must continue to service memory requests, despite hardware failures. Furthermore ...

Control of a Haptic Interface and a Micromachining Setup with an Open Source Real-Time System

Hannes Bleuler, Rolf Wüthrich, Evren Samur, Lionel Flaction, Ulrich Spälter, Pascal Maillard

Open source software have evolved into powerful tools for real-time control of mechatronic systems. They are of interest for academic purposes, as they promise high flexibility at low cost. In this paper, we investigate the performance of an open source co ...
