Asynchronous Decoding of LDPC Codes over BEC

Amin Karbasi, Amir Hesam Salavati, Saeid Haghighatshoar

LDPC codes are typically decoded by running a synchronous message passing algorithm over the corresponding bipartite factor graph (made of variable and check nodes). More specifically, each synchronous round consists of 1) updating all variable nodes based ...

Reactive Processing of RDF Streams of Events

Karl Aberer, Jean Paul Calbimonte Perez

Events on the Web are increasingly being produced in the form of data streams, and are present in many different scenarios and applications such as health monitoring, environmental sensing or social networks. The heterogeneity of event streams has raised t ...

Sleepers’ lag - study on motion and attention

Pierre Dillenbourg, Roland John Tormey, Mirko Raca

Human body-language is one of the richest and most obscure sources of information in inter-personal communication which we aim to re-introduce into the classroom’s ecosystem. In this paper we present our observations of student-to-student influence and mea ...

A Mapping-Scheduling Algorithm for Hardware Acceleration on Reconfigurable Platforms

David Atienza Alonso, Ivan Beretta

Reconfigurable platforms are a promising technology that offers an interesting trade-off between flexibility and performance, which many recent embedded system applications demand, especially in fields such as multimedia processing. These applications typi ...

How to Stop Under-Utilization and Love Multicores

Anastasia Ailamaki, Danica Porobic, Pinar Tözün, Iraklis Psaroudakis, Erietta Liarou

Designing scalable transaction processing systems on modern hardware has been a challenge for almost a decade. Hardware trends oblige software to overcome three major challenges against systems scalability: (1) Exploiting the abundant thread-level parallel ...

High-Performance Communication Primitives and Data Structures on Message-Passing Manycores : Broadcast and Map

Omid Shahmirzadi

The constant increase in single core frequency reached a plateau during recent years since the produced heat inside the chip cannot be cooled down by existing technologies anymore. An alternative to harvest more computational power per die is to fabricate ...

Methods to explore design space for MPEG RMC codec specifications

Marco Mattavelli, Endri Bezati, Simone Casale Brunet, Ghislain Roquier, Richard Thavot

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 ...

Parallelization of the distinct lattice spring model

Jian Zhao, Liang Sun, Jiannong Fang, Gaofeng Zhao

The distinct lattice spring model (DLSM) is a newly developed numerical tool for modeling rock dynamics problems, i.e. dynamic failure and wave propagation. In this paper, parallelization of DLSM is presented. With the development of parallel computing tec ...
