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.

STREX: Boosting Instruction Cache Reuse in OLTP Workloads Through Stratified Transaction Execution

Anastasia Ailamaki, Pinar Tözün, Xin Tong

Online transaction processing (OLTP) workload performance suffers from instruction stalls; the instruction footprint of a typical transaction exceeds by far the capacity of an L1 cache, leading to ongoing cache thrashing. Several proposed techniques remove ...

Alternating Control Flow Reconstruction

Johannes Kinder

Unresolved indirect branch instructions are a major obstacle for statically reconstructing a control flow graph (CFG) from machine code. If static analysis cannot compute a precise set of possible targets for a branch, the necessary conservative over-appro ...

Functional Modeling and Energetic Macroscopic Representation of Modular Multilevel Converters

Alfred Rufer, Michail Vasiladiotis, Nicolas Cherix

A key feature of Modular Multilevel Converters (MMC) is the continuous and independent nature of the branch currents. Therefore, a decoupled control of the line and partial bus currents is possible, unlike for classical topologies. To this end, several con ...

NOC-Out: Microarchitecting a Scale-Out Processor

Babak Falsafi, Boris Robert Grot, Pejman Lotfi Kamran

Scale-out server workloads benefit from many-core processor organizations that enable high throughput thanks to abundant request-level parallelism. A key characteristic of these workloads is the large instruction footprint that exceeds the capacity of priv ...

Querypoint Debugging

Claude Petitpierre, Salman Mirghasemi

To fix a bug, software developers have to examine the bug-gy execution to locate defects. They employ different ap-proaches (e.g., setting breakpoints, inserting printing statements in the code) to navigate over buggy execution and inspect program state at ...

An Abstract Interpretation-Based Framework for Control Flow Reconstruction from Binaries

Johannes Kinder

Due to indirect branch instructions, analyses on executables commonly suffer from the problem that a complete control flow graph of the program is not available. Data flow analysis has been proposed before to statically determine branch targets in many cas ...

Interpretation of neuronal response properties with simplified neuron models

Laurent Badel

Computational neuroscience is a branch of the neurosciences that attempts to elucidate the principles underlying the operation of neurons with the help of mathematical modeling. In contrast with a number of fields pursuing a tightly related goal, such as m ...

Temporal instruction fetch streaming

Anastasia Ailamaki, Babak Falsafi, Michael Ferdman

L1 instruction-cache misses pose a critical performance bottleneck in commercial server workloads. Cache access latency constraints preclude L1 instruction caches large enough to capture the application, library, and OS instruction working sets of these wo ...

Bio-inspired self-organizing cellular systems

Daniel Mange, Joël Rossier, Fabien Vannel

Bio-inspiration borrows three properties characteristic of living organisms: multicellular architecture, cellular division, and cellular differentiation. Implemented in silicon according to these properties, our self-organizing systems are able to grow, to ...

Design of Self-organizing Bio-inspired Systems

Daniel Mange, Joël Rossier

Self-organizing bio-inspired systems borrow three structural principles characteristic of living organisms: multicellular architecture, cellular division, and cellular differentiation. Implemented in silicon according to these principles, our cellular syst ...
