Scaling Language Features for Program Verification

Formal verification of real-world software systems remains challenging for a number of reasons, including lack of automation, friction in specifying properties, and limited support for the diverse programming paradigms used in industry. In this thesis we m ...

Concurrent Search Data Structures Can Be Blocking and Practically Wait-Free

Rachid Guerraoui, Tudor Alexandru David

We argue that there is virtually no practical situation in which one should seek a "theoretically wait-free" algorithm at the expense of a state-of-the-art blocking algorithm in the case of search data structures: blocking algorithms are simple, fast, and ...

RRB Vector: A Practical General Purpose Immutable Sequence

Martin Odersky, Tiark Rompf, Nicolas Alexander Stucki, Vlad Ureche

State-of-the-art immutable collections have wildly differing performance characteristics across their operations, often forcing programmers to choose different collection implementations for each task. Thus, changes to the program can invalidate the choice ...

Distributed Programming via Safe Closure Passing

Heather Christine Klug, Philipp Haller

Programming systems incorporating aspects of functional programming, e.g., higher-order func- tions, are becoming increasingly popular for large-scale distributed programming. New frameworks such as Apache Spark leverage functional techniques to provide hi ...

Surgical Precision JIT Compilers

Tiark Rompf, Hassan Chafi

Just-in-time (JIT) compilation of running programs provides more optimization opportunities than offline compilation. Modern JIT compilers, such as those in virtual machines like Oracle's HotSpot for Java or Google's V8 for JavaScript, rely on dynamic prof ...

Lightweight Snapshots and System-level Backtracking

George Candea, Edouard Bugnion, Vitaly Chipounov

We propose a new system-level abstraction, the lightweight immutable execution snapshot, which combines the immutable characteristics of checkpoints with the direct integration into the virtual memory subsystem of standard mutable address spaces. The abstr ...

Composing Relaxed Transactions

Rachid Guerraoui, Vincent Gramoli, Mihai Letia

As the classic 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 improvin ...

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 ...

A Quantitative Evaluation of the Contribution of Native Code to Java Workloads

Philippe Moret

Many performance analysis tools for Java focus on tracking executed bytecodes, but provide little support in determining the specific contribution of native code libraries. This paper introduces and assesses a portable approach for characterizing the amoun ...
