For Coordination, State Component Transitions

Simon Bliudze, Anastasia Mavridou, Radoslaw Szymanek, Alina Zolotukhina

Coordinating component behaviour and, in particular, concurrent access to resources is among the key difficulties of building large concurrent systems. To address this, developers must be able to manipulate high-level concepts, such as Finite State Machine ...

State Machine Replication

Nuno Filipe de Sousa Santos

Since their invention more than half a century ago, computers have gone from being just an handful of expensive machines each filling an entire room, to being an integral part of almost every aspect of modern life. Nowadays computers are everywhere: in our ...

Hardness Of Precedence Constrained Scheduling On Identical Machines

Ola Nils Anders Svensson

In 1966, Graham showed that a simple procedure called list scheduling yields a 2-approximation algorithm for the central problem of scheduling precedence constrained jobs on identical machines to minimize makespan. To date this has remained the best algori ...

Conditional hardness of precedence constrained scheduling on identical machines

Ola Nils Anders Svensson

Already in 1966, Graham showed that a simple procedure called list scheduling yields a 2-approximation algorithm for the central problem of scheduling precedence constrained jobs on identical machines to minimize makespan. Till this date it has remained th ...

An Optimal Linear-Time Algorithm for Interprocedural Register Allocation in High Level Synthesis Using SSA Form

Paolo Ienne, Philip Brisk, Ajay Kumar Verma

An optimal linear-time algorithm for interprocedural register allocation in high level synthesis is presented. Historically, register allocation has been modeled as a graph coloring problem, which is nondeterministic polynomial time-complete in general; ho ...

Model checking transactional memories

Rachid Guerraoui, Vasu Singh

Model checking transactional memories (TMs) is difficult because of the unbounded number, length, and delay of concurrent transactions, as well as the unbounded size of the memory. We show that, under certain conditions satisfied by most TMs we know of, th ...

2D-TUCKER Is PPAD-Complete

Tucker's lemma states that if we triangulate the unit disc centered at the origin and color the vertices with {1, 1,2, 2} in an antipodal way (if vertical bar z vertical bar = 1, then the sum of the colors of z and -z is zero), then there must be an edge F ...

Probabilistic Weighted Automata

Laurent Doyen

Nondeterministic weighted automata are finite automata with numerical weights on transitions. They define quantitative languages

L

that assign to each word

w

a real number

L(w)

. The value of an infinite word

w

is computed as the maximal value of al ...

A Notion of Glue Expressiveness for Component-Based Systems

Joseph Sifakis, Simon Bliudze

Comparison between different formalisms and models is often by flattening structure and reducing them to behaviourally equivalent models e.g. automaton and Turing machine. This leads to a notion of expressiveness which is not adequate for component-based s ...

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.
