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.

DejaVu: Accelerating Resource Allocation in Virtualized Environments

Dejan Novakovic, Dejan Kostic, Nedeljko Vasic, Ricardo Bianchini

Effective resource management of virtualized environments is a challenging task. State-of-the-art management systems either rely on analytical models or evaluate resource allocations by running actual experiments. However, both approaches incur a significa ...

System and method for in-vivo multi-path analysis of binary software

George Candea, Vitaly Chipounov, Volodymyr Kuznetsov

A system and method for in-vivo multi-path analysis and testing of binary software including binary device drivers is disclosed. The system and method may be used to test a binary software system and may comprise a virtual machine, a symbolic execution eng ...

Performance Profiling of Virtual Machines

Willy Zwaenepoel, Jiaqing Du

Profilers based on hardware performance counters are indispensable for performance debugging of complex software systems. All modern processors feature hardware performance counters, but current virtual machine monitors (VMMs) do not properly expose them t ...

SenGuard: Passive User Identification on Smartphones Using Multiple Sensors

Jiangyan Yang, Feng Yang

User identification and access control have become a high demand feature on mobile devices because those devices are wildly used by employees in corporations and government agencies for business and store increasing amount of sensitive data. This paper des ...

Why Nothing Matters: The Impact of Zeroing

Jennifer Bedke Sartor, Xi Yang

Memory safety defends against inadvertent and malicious misuse of memory that may compromise program correctness and security. A critical element of memory safety is zero initialization. The direct cost of zero initialization is surprisingly high: up to 12 ...

Performance Profiling in a Virtualized Environment

Willy Zwaenepoel, Jiaqing Du

Virtualization is a key enabling technology for cloud computing. Many applications deployed in a cloud run in virtual machines. However, profilers based on CPU performance counters do not work well in a virtualized environment. In this paper, we explore th ...

Language Virtualization for Heterogeneous Parallel Computing

Martin Odersky, Tiark Rompf, Hassan Chafi

As heterogeneous parallel systems become dominant, application developers are being forced to turn to an incompatible mix of low level programming models (e.g. OpenMP, MPI, CUDA, OpenCL). However, these models do little to shield developers from the diffic ...

Precise static analysis of untrusted driver binaries

Johannes Kinder

Most closed source drivers installed on desktop systems today have never been exposed to formal analysis. Without vendor support, the only way to make these often hastily written, yet critical programs accessible to static analysis is to directly work at t ...

A Realistic Simulator for the Design and Evaluation of Intelligent Vehicles

Alcherio Martinoli, Sven Adrian Gowal

The number of vehicles hitting the road each day is rapidly increasing, and several problems, such as traffic conges- tion or driver safety, can no longer be solved in the same fashion as before. Intelligent transportation systems could potentially solve p ...
