Eliminating unscalable communication in transaction processing

Anastasia Ailamaki, Frederick Ryan Johnson, Ippokratis Pandis

Multicore hardware demands software parallelism. Transaction processing workloads typically exhibit high concurrency, and, thus, provide ample opportunities for parallel execution. Unfortunately, because of the characteristics of the application, transacti ...

Methods to explore design space for MPEG RMC codec specifications

Marco Mattavelli, Simone Casale Brunet, Endri Bezati, Ghislain Roquier, Richard Thavot, Abdallah Alaaeldin Abdelaziz Elguindy

The recent MPEG Reconfigurable Media Coding (RMC) standard aims at defining media processing specifications (e.g. video codecs) in a form that abstracts from the implementation platform, but at the same time is an appropriate starting point for implementat ...

Scale-Out Processors

Pejman Lotfi Kamran

Global-scale online services, such as Google’s Web search and Facebook’s social networking, run in large-scale datacenters. Due to their massive scale, these services are designed to scale out (or distribute) their respective loads and datasets across thou ...

SLICC: Self-Assembly of Instruction Cache Collectives for OLTP Workloads

Anastasia Ailamaki, Pinar Tözün

Online transaction processing (OLTP) is at the core of many data center applications. OLTP workloads are known to have large instruction footprints that foil existing L1 instruction caches resulting in poor overall performance. Prefetching can reduce the i ...

Quantifying the Mismatch between Emerging Scale-Out Applications and Modern Processors

Anastasia Ailamaki, Babak Falsafi, Michael Ferdman, Mohammad Alisafaee, Yusuf Onur Koçberber, Stavros Volos, Ilknur Cansu Kaynak, Adrian Daniel Popescu, Al Mutaz Adileh, Dorde Jevdic

Emerging scale-out workloads require extensive amounts of computational resources. However, data centers using modern server hardware face physical constraints in space and power, limiting further expansion and calling for improvements in the computational ...

Making Wide-Issue VLIW Processors Viable on FPGAs

Paolo Ienne, Madhura Purnaprajna

Soft and highly-customized processors are emerging as a common way to efficiently control large amount of computing resources available on FPGAs. Yet, some processor architectures of choice for DSP and media applications, such as wide-issue VLIW processors ...

Scale-Out Processors

Babak Falsafi, Michael Ferdman, Boris Robert Grot, Yusuf Onur Koçberber, Pejman Lotfi Kamran, Stavros Volos, Javier Picorel Obando, Al Mutaz Adileh, Dorde Jevdic

Scale-out datacenters mandate high per-server throughput to get the maximum benefit from the large TCO investment. Emerging applications (e.g., data serving and web search) that run in these datacenters operate on vast datasets that are not accommodated by ...

Three-dimensional harmonic holographic microcopy using nanoparticles as probes for cell imaging: erratum

Demetri Psaltis, Ye Pu, Ye Pu, Rachel Grange, Chia-Lung Hsieh

An error was made in calculating the polarization dependent second harmonic response of barium titanate nanoparticles. We have corrected the error and repeated the comparison with the experimental results. (C) 2010 Optical Society of America ...

TurboTag: Lookup Filtering to Reduce Coherence Directory Power

Babak Falsafi, Michael Ferdman, Pejman Lotfi Kamran, Daniel Crisan

On-chip coherence directories of today’s multi-core systems are not energy efficient. Coherence directories dissipate a significant fraction of their power on unnecessary lookups when running commercial server and scientific workloads. These workloads have ...

MPSoC Design using Application-Specific Architecturally Visible Communication

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

This paper advocates the placement of Architecturally Visible Communication (AVC) buffers between adjacent cores in MPSoCs to provide high-throughput communication for streaming applications. Producer/consumer relationships map poorly onto cache-based MPSo ...
