Fast and Robust Memory Reclamation for Concurrent Data Structures

Rachid Guerraoui, Mihail Igor Zablotchi, Oana Maria Balmau

In concurrent systems without automatic garbage collection, it is challenging to determine when it is safe to reclaim memory, especially for lock-free data structures. Existing concurrent memory reclamation schemes are either fast but do not tolerate proce ...

On Verifying Causal Consistency

Rachid Guerraoui, Jad Hamza

Causal consistency is one of the most adopted consistency criteria for distributed implementations of data structures. It ensures that operations are executed at all sites according to their causal precedence. We address the issue of verifying automaticall ...

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 ...

Deductive Synthesis and Repair

Etienne Kneuss

In this thesis, we explore techniques for the development of recursive functional programs over unbounded domains that are proved correct according to their high-level specifications. We present algorithms for automatically synthesizing executable code, st ...

Traversal Query Language For Scala.Meta

Eugene Burmako, Eric Beguet

With the rise of metaprogramming in Scala, manipulating ASTs has become a daily job. Yet the standard API provides only low-level mechanisms to transform or to collect information on those data structures. Moreover, those mechanisms often force the program ...

Asynchronous memory access chaining

Babak Falsafi, Boris Robert Grot, Yusuf Onur Koçberber

In-memory databases rely on pointer-intensive data structures to quickly locate data in memory. A single lookup operation in such data structures often exhibits long-latency memory stalls due to dependent pointer dereferences. Hiding the memory latency by ...

Interoperation between Miniboxing and Other Generics Translations

Milos Stojanovic

Generics allow programmers to design algorithms and data structures that operate in the same way regardless of the data used by abstracting over data types. Generics are useful as they improve the programmer’s productivity by raising the level of abstracti ...

Spatial joins in main memory: implementation matters!

Darius Sidlauskas

A recent PVLDB paper reports on experimental analyses of ten spatial join techniques in main memory. We build on this comprehensive study to raise awareness of the fact that empirical running time performance findings in main-memory settings are results of ...

Achieving Efficient Work-Stealing for Data-Parallel Collections

Martin Odersky, Aleksandar Prokopec

In modern programming high-level data-structures are an important foundation for most applications. With the rise of the multi-core era, there is a growing trend of supporting data-parallel collection operations in general purpose programming languages and ...

STM in the Small: Trading Generality for Performance in Software Transactional Memory

Aleksandar Dragojevic

Data structures implemented using software transactional memory (STM) have a reputation for being much slower than data structures implemented directly from low-level primitives such as atomic compare-and-swap (CAS). In this paper we present a specialized ...
