A Primer on Hardware Prefetching

Babak Falsafi

Since the 1970’s, microprocessor-based digital platforms have been riding Moore’s law, allowing for doubling of density for the same area roughly every two years. However, whereas microprocessor fabrication has focused on increasing instruction execution r ...

Way Stealing: A Unified Data Cache and Architecturally Visible Storage for Instruction Set Extensions

Edoardo Charbon, Paolo Ienne, Ties Jan Henderikus Kluter, Philip Brisk

Way Stealing is a simple architectural modification to a cache-based processor that increases the data bandwidth to and from application-specific instruction set extensions (ISEs), which increase performance and reduce energy consumption. Way Stealing offe ...

ALLARM: Optimizing Sparse Directories for Thread-Local Data

Amitabha Roy

Large-scale cache-coherent systems often impose unnecessary overhead on data that is thread-private for the whole of its lifetime. These include resources devoted to tracking the coherence state of the data, as well as unnecessary coherence messages sent o ...

Renovation strategies: use and changes to Lisbon’s domestic spaces

Catarina Wall Gago

This contribution proposes a comparative analysis of the original and transformed domestic layout in recent renovations of late 18th and early 19th century housing in Lisbon’s Baixa Pombalina. We specifically look at modifications of room function and conn ...

Putting the Pieces Together: The Construction of a Reliable Virtualizing Object-Based Storage Stack

Raja Appuswamy

The operating system storage stack is an important software component, but it faces several reliability threats. The research community has come up with many solutions to address individual parts of this reliability problem. However, when considering the b ...

OLTP in Wonderland -- Where do cache misses come from in major OLTP components?

Anastasia Ailamaki, Pinar Tözün

For several decades, online transaction processing has been one of the main applications that drives innovations in the data management ecosystem, and in turn the database and computer architecture communities. Despite the novel approaches from industry an ...

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 ...

Runtime 3-D Stacked Cache Management for Chip-Multiprocessors

Giovanni De Micheli

These-dimensional (3-D) memory stacking is one of the most promising solutions to memory bandwidth problems in chip multiprocessors. In this work, we propose an efficient runtime 3-D cache management technique which takes advantage of the lower latencies t ...

Scalable Media Coding Enabling Content-Aware Networking

Daniele Renzi

Increasingly popular multimedia services are expected to play a dominant role in the future of the Internet. In this context, it is essential that content-aware networking (CAN) architectures explicitly address the efficient delivery and processing of mult ...

Bridging Islands of Specialized Code using Macros and Reified Types

Nicolas Alexander Stucki, Vlad Ureche

Parametric polymorphism in Scala suffers from the usual drawback of erasure on the Java Virtual Machine: primitive values are boxed, leading to indirect access, wasteful use of heap memory and lack of cache locality. For performance-critical parts of the c ...
