Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Multi-Grain Coherence Directory

Babak Falsafi

Conventional directory coherence operates at the finest granularity possible, that of a cache block. While simple, this organization fails to exploit frequent application behavior: at any given point in time, large, continuous chunks of memory are often ac ...

Utility-driven Data Acquisition in Participatory Sensing

Karl Aberer, Immanuel Trummer, Mehdi Riahi

Participatory sensing (PS) is becoming a popular data acquisition means for interesting emerging applications. However, as data queries from these applications increase, the sustainability of this platform for multiple concurrent applications is at stake. ...

Particle Manifold Method (PMM) for Multiscale Continuous-Discontinuous Analysis

Liang Sun

It is important to consider the microstructure of a material when studying the macroscopic mechanical properties. Although special equipments have been used for micromechanics study through experimental tests, it is limited by instruments and reproducibili ...

Multiscale Hemodynamics Using GPU Clusters

Efthimios Kaxiras

The parallel implementation of MUPHY, a concurrent multiscale code for large-scale hemodynamic simulations in anatomically realistic geometries, for multi-GPU platforms is presented. Performance tests show excellent results, with a nearly linear parallel s ...

DSPE: Domain Specific Language for Parallel Real-Time Stream Processing

Tiziano Leidi

Today, the evolution of software solutions for parallel processing is strong, as a consequence of the mainstream introduction of chip-level multiprocessors. These types of parallel processors, which include general-purpose multi-cores and graphical process ...

Approximation Algorithms for Modern Multi-Processor Scheduling Problems

Martin Niemeier

This thesis is devoted to the design and analysis of algorithms for scheduling problems. These problems are ubiquitous in the modern world. Examples include the optimization of local transportation, managing access to concurrent resources like runways at a ...

Multi-Lane FlowPools: A Detailed Look

Martin Odersky, Philipp Haller, Aleksandar Prokopec, Tobias Schlatter

FlowPools, proposed by are a powerful way to express dataflow logic in highly parallelized applications. The original paper proposes two ways of implementing a FlowPool: Single-Lane FlowPools (SLFP) and Multi-Lane FlowPools (MLFP). While SLFPs showed decen ...

Fine-grained Parallel Traversals of Irregular Data Structures

James Richard Larus

Fine-grain data parallelism is increasingly common in mainstream processors in the form of long vectors and on-chip GPUs. This paper develops compiler and runtime support to exploit such data parallelism for non-numeric, non-graphic, irregular parallel tas ...

On the Performance of Software Transactional Memory

Aleksandar Dragojevic

The recent proliferation of multi-core processors has moved concurrent programming into mainstream by forcing increasingly more programmers to write parallel code. Using traditional concurrency techniques, such as locking, is notoriously difficult and has ...

Shortening design time through multiplatform simulations with a portable OpenCL golden-model: the LDPC decoder case

Andreas Peter Burg, Paolo Ienne, Georgios Karakonstantis, David Novo Bruna, Madhura Purnaprajna

Hardware designers and engineers typically need to explore a multi-parametric design space in order to ﬁnd the best conﬁguration for their designs using simulations that can take weeks to months to complete. For example, designers of special purpose chips ...
