Rust is a new systems programming language that promises to overcome the seemingly
fundamental tradeoff between high-level safety guarantees and low-level control over …

Iris is a framework for higher-order concurrent separation logic, which has been
implemented in the Coq proof assistant and deployed very effectively in a wide variety of …

Large-scale distributed systems often rely on replicated databases that allow a programmer
to request different data consistency guarantees for different operations, and thereby control …

Abstraction is key to understanding and reasoning about large computer systems.
Abstraction is simple to achieve if the relevant data structures are disjoint, but rather difficult …

Concurrent separation logics (CSLs) have come of age, and with age they have
accumulated a great deal of complexity. Previous work on the Iris logic attempted to reduce …

To avoid data races, concurrent operations should either be at distinct times or on distinct
data. Atomicity is the abstraction that an operation takes effect at a single, discrete instant in …

Compositional abstractions underly many reasoning principles for concurrent programs: the
concurrent environment is abstracted in order to reason about a thread in isolation; and …

Weak memory models formalize the inconsistent behaviors that one can expect to observe
in multithreaded programs running on modern hardware. In so doing, however, they …

Combining the actor-model with shared memory for performance is efficient but can
introduce data-races. Existing approaches to static data-race freedom are based on …

Fine-grained concurrent programs are difficult to get right, yet play an important role in
modern-day computers. We want to prove strong specifications of such programs, with …
