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 ...
Amodernmanycore architecture can be viewed as a distributed system with explicit message passing to communicate between cores. Ensuring the consistency of shared state replicated over several cores is the key to the well functioning of such a system. Yet, ...
ERLANG is an industrially successful functional language that uses the Actor model for concurrency. It supports the message-passing paradigm by providing pattern-matching over received messages. Unfortunately coding synchronisation between multiple process ...

Transactional memory (TM) is a promising paradigm for concurrent programming, in which threads of an application communicate, and synchronize their actions, via inmemory transactions. Each transaction can perform any number of operations on shared data, an ...
Message-based concurrency using actors has the potential to scale from multicore processors to distributed systems. However, several challenges remain until actor-based programming can be applied on a large scale. First, actor implementations must be effic ...
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 ...
This paper presents software implementation speed records for modular multiplication arithmetic on the synergistic processing elements of the Cell broadband engine (Cell) architecture. The focus is on moduli which are of special interest in elliptic curve ...

An important application of unique object references is safe and efficient message passing in concurrent object-oriented programming. However, to prevent the ill effects of aliasing, practical systems often severely restrict the shape of messages passed by ...
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 ...
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 ...
