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.

Laws of Order: Expensive Synchronization in Concurrent Algorithms Cannot be Eliminated

Rachid Guerraoui, Hagit Albo Attiya

Building correct and efﬁcient concurrent algorithms is known to be a difﬁcult problem of fundamental importance. To achieve ef- ﬁciency, designers try to remove unnecessary and costly synchro- nization. However, not only is this manual trial-and-error proc ...

Orleans: Cloud Computing for Everyone

James Richard Larus

Cloud computing is a new computing paradigm, combining diverse client devices -- PCs, smartphones, sensors, single-function, and embedded -- with computation and data storage in the cloud. As with every advance in computing, programming is a fundamental ch ...

Atomic boxes: coordinated exception handling with transactional memory

Vincent Gramoli, Pascal Felber

In concurrent programs raising an exception in one thread does not prevent others from operating on an inconsistent shared state. Instead, exceptions should ideally be handled in coordination by all the threads that are affected by their cause. In this pap ...

Democratizing Transactional Programming

Rachid Guerraoui, Vincent Gramoli

The Transaction abstraction is arguably one of the most appealing middleware paradigms. It lies typically between the programmer of a concurrent or distributed application on the one hand, and the operating system with the underlying network on the other h ...

Cache-Aware Lock-Free Concurrent Hash Tries

Martin Odersky, Aleksandar Prokopec

This report describes an implementation of a non-blocking concurrent shared-memory hash trie based on single-word compare-and-swap instructions. Insert, lookup and remove operations modifying different parts of the hash trie can be run independent of each ...

Speculative Linearizability

Rachid Guerraoui, Viktor Kuncak, Giuliano Losa

Linearizability is a key design methodology for reasoning about implementations of concurrent abstract data types in both shared memory and message passing systems. It provides the illusion that operations execute sequentially and fault-free, despite the a ...

Student mini-kernel project based on an FPGA board

André Schiper, Zarko Milosevic, Omid Shahmirzadi

The paper describes a mini-kernel project in the context of a Concurrent Programming course. The goal of the project is to implement Java monitors and interrupt handling. The platform for the project is an FPGA board developed initially at EPFL for Compute ...

D-finder 2: Towards efficient correctness of incremental design

Joseph Sifakis

D-Finder 2 is a new tool for deadlock detection in concurrent systems based on effective invariant computation to approximate the effects of interactions among modules. It is part of the BIP framework, which provides various tools centered on a component-b ...

Programming the Cloud

James Richard Larus

Client + cloud computing is a disruptive, new computing platform, combining diverse client devices -- PCs, smartphones, sensors, and single-function and embedded devices -- with the unlimited, on-demand computation and data storage offered by cloud computi ...
