Efficient System-Enforced Deterministic Parallelism

Bryan Alexander Ford

Deterministic execution offers many benefits for debugging, fault tolerance, and security. Current methods of executing parallel programs deterministically, however, often incur high costs, allow misbehaved software to defeat repeatability, and transform t ...

Deprecating the Observer Pattern

Martin Odersky, Tiark Rompf, Ingo Maier

Programming interactive systems by means of the observer pattern is hard and error-prone yet is still the implementation standard in many production environments. We present an approach to gradually deprecate observers in favor of reactive programming abst ...

Concurrent Programming Paradigms, A Comparison in Scala

Rachid Guerraoui, Martin Odersky, Mohsen Lesani

There is a rapid rise of multi-cores in recent hardware architectures. To exploit computational power of multi-core architectures, software should shift to be as concurrent as possible; and therefore should have concurrency control mechanisms. There are di ...

TMunit: Testing Transactional Memories

Vincent Gramoli, Pascal Felber

Transactional memory (TM) is expected to become a widely used parallel programming paradigm for multi-core architectures. To reach this goal, we need tools that do not only help develop TMs, but also test them and evaluate them on a wide range of workloads ...

Performance prediction and race detection in message-passing parallel applications

Basile Schäli

The combination of low cost clusters and multicore processors lowers the barrier for accessing massive amounts of computing power. As computational sciences advance, the use of in silico simulations to complement in vivo experiments promises parallel progr ...

Why STM can be more than a Research Toy

Rachid Guerraoui, Vincent Gramoli, Aleksandar Dragojevic, Pascal Felber

Software Transactional Memory (STM) promises to simplify concurrent programming without requiring speciﬁc hardware support. Yet, STM’s credibility lies on the extent to which it can leverage multi-cores to outperform sequential code. A recent CACM paper [8 ...

High-Performance Transactional Event Processing

Rachid Guerraoui, Jesper Honig Spring, Antonio Cunei

This paper presents a transactional framework for low-latency, high-performance, concurrent event processing in Java. At the heart of our framework lies Reﬂexes, a restricted programming model for highly responsive systems. A Reﬂex task is an event process ...

Software Transactional Memory on Relaxed Memory Models

Rachid Guerraoui, Vasu Singh

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 ...

Simplifying Distributed System Development

Viktor Kuncak, Dejan Kostic, Maysam Yabandeh, Nedeljko Vasic

Distributed systems are difficult to design and develop. The difficulties arise both in basic safety correctness properties, and in achieving high performance. As a result of this complexity, the implementation of a distributed system often contains the ba ...

How to Make Stream Processing More Mainstream

Marco Mattavelli

Stream processing has a long history as a way of describing and implementing speciﬁc kinds of computational processes. So far, however, it has largely remained an exotic ﬁeld of endeavor, with relatively small momentum compared to traditional von Neumann c ...
