PaRiS: Causally Consistent Transactions with Non-blocking Reads and Partial Replication

Willy Zwaenepoel, Diego Didona, Kristina Spirovska

Geo-replicated data platforms are at the backbone of several large-scale online services. Transactional Causal Consistency (TCC) is an attractive consistency level for building such platforms. TCC avoids many anomalies of eventual consistency, eschews the ...

Resistive Switching Memory Architecture Based on Polarity Controllable Selectors

Alexandre Sébastien Julien Levisse, Pierre-Emmanuel Julien Marc Gaillardon

With the continuous scaling of CMOS technology, integrating an embedded high-density non-volatile memory appears to be more and more costly and technologically challenging. Beyond floating-gate memory technologies, bipolar resistive random access memories ...

A paradox of eventual linearizability in shared memory

Rachid Guerraoui

This paper compares, for the rst time, the computational power of linearizable objects with that of eventually linearizable ones. We present the following paradox. We show that, unsurprisingly, no set of eventually linearizable objects can (1) implement an ...

Tight Failure Detection Bounds on Atomic Object Implementations

Rachid Guerraoui

This article determines the weakest failure detectors to implement shared atomic objects in a distributed system with crash-prone processes. We first determine the weakest failure detector for the basic register object. We then use that to determine the we ...

Software Transactional Memory on Relaxed Memory Models

Rachid Guerraoui

Pseudo-code descriptions of STMs assume sequentially consistent program execution and atomicity of high-level STM operations like read, write, and commit. These assumptions are often violated in realistic settings, as STM implementations run on relaxed mem ...

The Semantics of Progress in Lock-Based Transactional Memory

Rachid Guerraoui

Transactional memory (TM) is a promising paradigm for concurrent programming. Whereas the number of TM implementations is growing, however, little research has been conducted to precisely define TM semantics, especially their progress guarantees. This pape ...

Reconfigurable Distributed Storage for Dynamic Networks

Vincent Gramoli, Seth Gilbert

This paper presents a new algorithm for implementing a reconfigurable distributed shared memory in an asynchronous dynamic network. The algorithm guarantees atomic consistency (linearizability) in all executions in the presence of arbitrary crash failures ...

Mechanisms for store-wait-free multiprocessors

Anastasia Ailamaki, Babak Falsafi

Store misses cause significant delays in shared-memory multiprocessors because of limited store buffering and ordering constraints required for proper synchronization. Today, programmers must choose from a spectrum of memory consistency models that reduce ...

Anonymous and fault-tolerant shared-memory computing

Rachid Guerraoui

The vast majority of papers on distributed computing assume that processes are assigned unique identifiers before computation begins. But is this assumption necessary? What if processes do not have unique identifiers or do not wish to divulge them for reas ...

How Fast Can a Very Robust Read Be?

Rachid Guerraoui

This paper studies the time complexity of reading unauthenticated data from a distributed storage made of a set of failure-prone base objects. More specifically, we consider the abstraction of a robust read/write storage that provides wait-free access to u ...
