Software Support for Non-Volatile Memory (NVM) Programming

Non-Volatile Memory (NVM) is an emerging type of memory device that provides fast, byte-addressable, and high-capacity durable storage. NVM sits on the memory bus and allows durable data structures designs similar to the in-memory equivalent ones. Expensiv ...

A Hybrid Cache HW/SW Stack for Optimizing Neural Network Runtime, Power and Endurance

David Atienza Alonso, Marina Zapater Sancho, Alexandre Sébastien Julien Levisse, William Andrew Simon

Hybrid caches consisting of both SRAM and emerging Non-Volatile Random Access Memory (eNVRAM) bitcells increase cache capacity and reduce power consumption by taking advantage of eNVRAM's small area footprint and low leakage energy. However, they also inhe ...

Exploring the Extent in the Visual Field of the Honeycomb and Extinction Illusions

Michael Herzog, Aline Françoise Cretenoud

There are situations in which what is perceived in central vision is different to what is perceived in the periphery, even though the stimulus display is uniform. Here, we studied two cases, known as the Extinction illusion and the Honeycomb illusion, invo ...

Fine-Grain Checkpointing with In-Cache-Line Logging

James Richard Larus, David Teksen Aksun, Nachshon Cohen

Non-Volatile Memory offers the possibility of implementing high-performance, durable data structures. However, achieving performance comparable to well-designed data structures in non-persistent (transient) memory is difficult, primarily because of the cos ...

RRAM Crossbar Arrays for Storage Class Memory Applications : Throughput and Density Considerations

Alexandre Sébastien Julien Levisse

As more and more high density memories are required to satisfy the Internet of Things ecosystem, academics and industrials are looking for an intermediate solution to fill the gap between DRAM and Flash NAND in the memory hierarchy. The emergence of Resist ...

Practical erasure codes for storage systems: The study of entanglement codes, an approach that propagates redundancy to increase reliability and performance

Verónica del Carmen Estrada Galiñanes

This dissertation deals with the design of practical erasure codes for storage systems. Hardware and logical disk failures are a common source of system failures that may lead to data loss. Nevertheless, it is predicted that spinning disks would remain the ...

Reducing circuit design complexity for neuromorphic machine learning systems based on Non-Volatile Memory arrays

Yusuf Leblebici, Alessandro Fumarola

Machine Learning (ML) is an attractive application of Non-Volatile Memory (NVM) arrays [1,2]. However, achieving speedup over GPUs will require minimal neuron circuit sharing and thus highly area-efficient peripheral circuitry, so that ML reads and writes ...

Querying Persistent Graphs using Solid State Storage

Manoussos Gavriil Athanassoulis

Recent advances in solid state technology have led to the introduction of Solid State Drives (SSDs). Todays SSDs store data persistently using NAND flash memory. While SSDs are more expensive than hard disks when measured in dollars per gigabyte, they are ...

Approximate Probabilistic Tree Indexing for Partitionable Data

Anastasia Ailamaki, Manoussos Gavriil Athanassoulis

Today we experience a shift both in storage technologies and in workloads characteristics. Firstly, solid state disks (SSD) (using flash, PCM or other low-level technologies) emerge as viable competitors of hard disk drives (HDD). Secondly, the increasing ...

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.
