Transactions in the Jungle

Rachid Guerraoui, Michal Kapalka, Vasu Singh

Transactional memory (TM) has shown potential to simplify the task of writing concurrent programs. Inspired by classical work on databases, formal definitions of the semantics of TM executions have been proposed. Many of these definitions assumed that acce ...

Aether: A scalable approach to logging

Anastasia Ailamaki, Frederick Ryan Johnson, Manoussos Gavriil Athanassoulis, Ippokratis Pandis, Radu Ioan Stoica

The shift to multi-core hardware brings new challenges to database systems, as the software parallelism determines performance. Even though database systems traditionally accommodate simultaneous requests, a multitude of synchronization barriers serialize ...

Data-Oriented Transaction Execution

Anastasia Ailamaki, Frederick Ryan Johnson, Ippokratis Pandis

While hardware technology has undergone major advancements over the past decade, transaction processing systems have remained largely unchanged. The number of cores on a chip grows exponentially, following Moore's Law, allowing for an ever-increasing numbe ...

The VELOX Transactional Memory Stack

Rachid Guerraoui, Vincent Gramoli, Michal Kapalka, Aleksandar Dragojevic, Pascal Felber

The adoption of multi- and many-core architectures for mainstream computing undoubtedly brings profound changes in the way software is developed. In particular, the use of fine grained locking as the multi-core programmer’s coordination methodology is cons ...

Leveraging Parallel Nesting in Transactional Memory

Rachid Guerraoui, Michal Kapalka, Aleksandar Dragojevic

Exploiting the emerging reality of affordable multi-core architectures goes through providing programmers with simple abstractions that would enable them to easily turn their sequential programs into concurrent ones that expose as much parallelism as possi ...

Model checking transactional memories

Rachid Guerraoui, Vasu Singh

Model checking transactional memories (TMs) is difficult because of the unbounded number, length, and delay of concurrent transactions, as well as the unbounded size of the memory. We show that, under certain conditions satisfied by most TMs we know of, th ...

Composing Relaxed Transactions

Rachid Guerraoui, Vincent Gramoli, Mihai Letia

As the classical transactional abstraction is sometimes considered too restrictive in leveraging parallelism, a lot of work has been devoted to devising relaxed transactional models with the goal of improving concurrency. Nevertheless, the quest for improv ...

Decoupling contention management from scheduling

Anastasia Ailamaki, Frederick Ryan Johnson, Radu Ioan Stoica

Many parallel applications exhibit unpredictable communication between threads, leading to contention for shared objects. The choice of contention management strategy impacts strongly the performance and scalability of these applications: spinning provides ...
