To program parallel systems efficiently and easily, a wide range of programming models
have been proposed, each with different choices concerning synchronization and …

Parallelism is often required for performance. In these situations an excess of non-
determinism is harmful as it means the program can have several different behaviours or …

This paper introduces ctrees, a monad for modeling nondeterministic, recursive, and impure
programs in Coq. Inspired by Xia et al.'s itrees, this novel data structure embeds …

Software-intensive systems in most domains, from autonomous vehicles to health, are
becoming predominantly parallel to efficiently manage large amount of data in short (even …

ORCA is a concurrent and parallel garbage collector for actor programs, which does not
require any STW steps, or synchronization mechanisms, and that has been designed to …

Mutable value semantics is a programming discipline that upholds the independence of
values to support local reasoning. In the discipline's strictest form, references become …

Non-determinism in a concurrent or distributed setting may lead to many different runs or
executions of a program. This paper presents a method to reproduce a specific run for non …

The actor paradigm supports the natural expression of concurrency. It has inspired the
development of several actor-based languages, whose adoption depends, to a large extent …

The ubiquity of multicore computers has forced programming language designers to rethink
how languages express parallelism and concurrency. This has resulted in new language …

Concurrent programs often make use of futures, handles to the results of asynchronous
operations. Futures provide means to communicate not yet computed results, and simplify …
