Self-organizing Systems Based on Bio-inspired Properties

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 ...

Dynamic feature selection for hardware prediction

Babak Falsafi

Most hardware predictors are table based (e.g. two-level branch predictors) and have exponential size growth in the number of input bits or features (e.g. previous branch outcomes). This growth severely limits the amount of predictive information that such ...

Simulation sampling with live-points

Babak Falsafi

Current simulation-sampling techniques construct accurate model state for each measurement by continuously warming large microarchitectural structures (e.g., caches and the branch predictor) while functionally simulating the billions of instructions betwee ...

TurboSMARTS: Accurate microarchitecture simulation sampling in minutes

Babak Falsafi

Recent research proposes accelerating processor microarchitecture simulation through statistical sampling. Prior simulation sampling approaches construct accurate model state for each measurement by continuously warming large microarchitectural structures ...

Dynamically Trading Frequency for Complexity in a GALS Microprocessor

Microprocessors are traditionally designed to provide “best overall” performance across a wide range of applications and operating environments. Several groups have proposed hardware techniques that save energy by “downsizing” hardware resources that are u ...

Dynamic Data Dependence Tracking and Its Application to Branch Prediction

Lei Chen

To continue to improve processor performance, microarchitects seek to increase the effective instruction level parallelism (ILP) that can be exploited in applications. A fundamental limit to improving ILP is data dependences among instructions. If data dep ...

Using Cohort-Scheduling to Enhance Server Performance

James Richard Larus

A server application is commonly organized as a collection of concurrent threads, each of which executes the code necessary to process a request. This software architecture, which causes frequent control transfers between unrelated pieces of code, decrease ...

Affine Short Rate Models

Damir Filipovic

We give a complete characterization of affine term structure (ATS) models based on a general non-negative Markov short rate process. This applies to the classical Cox—Ingersoll—Ross (CIR) model but includes as well short rate processes with jumps. We provi ...

Analytical approximations for real values of the Lambert W- function

David Andrew Barry

The Lambert W is a transcendental function defined by solutions of the equation W exp(W) = x. For real values of the argument, x, the W-function has two branches, W-0 (the principal branch) and W-1 (the negative branch). A survey of the literature reveals ...

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.
