Transactions in the Jungle

Rachid Guerraoui, Michal Kapalka, Vasu Singh

Transactional memory (TM) has shown potential to simplify the task of writing concurrent programs. However, the semantics of interactions between transactions managed by a TM and non-transactional operations, while widely studied, lacks a clear formal spec ...

Preventing versus Curing: Avoiding Conflicts in Transactional Memories

Rachid Guerraoui, Aleksandar Dragojevic, Vasu Singh

Transactional memories are typically speculative and rely on contention managers to cure conflicts. This paper explores a complementary approach that prevents conflicts by scheduling transactions according to predictions on their access sets. We first expl ...

Cooperative Update Exchange in the Youtopia System

Christoph Koch

Youtopia is a platform for collaborative management and integration of relational data. At the heart of Youtopia is an update exchange abstraction: changes to the data propagate through the system to satisfy user-specified mappings. We present a novel chan ...

On the Correctness of Transactional Memory

Rachid Guerraoui, Michal Kapalka

Transactional memory (TM) is perceived as an appealing alternative to critical sections for general purpose concurrent programming. Despite the large amount of recent work on TM implementations, however, very little effort has been devoted to precisely def ...

Completeness and Nondeterminism in Model Checking Transactional Memories

Rachid Guerraoui, Vasu Singh

Software transactional memory (STM) offers a disciplined concurrent programming model for exploiting the parallelism of modern processor architectures. This paper presents the first \emph{deterministic} specification automata for strict serializability and ...

Dynamic Prediction based Scheduling for TM

Anmol Tomar

Transactional memory (TM) provides an intuitive and simple way of writing parallel programs. TMs execute parallel programs speculatively and deliver better performance than conventional lock based parallel programs. However, in certain scenarios when an ap ...

STMBench7: A Benchmark for Software Transactional Memory

Rachid Guerraoui, Michal Kapalka

Software transactional memory (STM) is a promising technique for controlling concurrency in modern multi-processor architectures. STM aims to be more scalable than explicit coarse-grained locking and easier to use than fine-grained locking. However, STM im ...

Transactional Memory

James Richard Larus

The advent of multicore processors has renewed interest in the idea of incorporating transactions into the programming model used to write parallel programs. This approach, known as transactional memory, offers an alternative, and hopefully better, way to ...

Comparison of Database Replication Techniques Based on Total Order Broadcast

André Schiper, Matthias Wiesmann

In this paper, we present a performance comparison of database replication techniques based on total order broadcast. While the performance of total order broadcast-based replication techniques has been studied in previous papers, this paper presents many ...
