WebAssembly (Wasm) is a virtual instruction set architecture designed for portability, performance, safety, and formal rigour. After its initial release, it has seen wide adoption across diverse ecosystems, such as the Web, edge computing, distributed computing, mobile, embedded systems, and others. Recently, release 2.0 of Wasm was published, which represents a step forward towards a […]

Rewriting for monoidal closed categories David Sprunger, Dan Ghica, Fabio Zanasi and Mario Alvarez-Picallo.  This paper develops a formal string diagram language for monoidal closed categories. Previous workhas shown that string diagrams for freely generated symmetric monoidal categories can be viewedas hypergraphs with interfaces, and the axioms of these categories can be realized by rewritingsystems. This work proposes […]

The Theory of Call-by-Value Solvability The denotational semantics of the untyped $\lambda$-calculus is a well developed field built around the concept of solvable terms, which are elegantly characterized in many different ways. In particular, unsolvable terms provide a consistent notion of meaningless term. The semantics of the untyped call-by-value lambda-calculus is instead still in its […]

High-Level Type-Safe Effect Handlers in C++ DAN GHICA, Huawei Research, UK SAM LINDLEY, The University of Edinburgh, UK MARCOS MAROÑAS BRAVO, Huawei Research, UK MACIEJ PIRÓG, Huawei Research, UK Effect handlers allow the programmer to implement computational effects, such as custom error handling, various forms of lightweight concurrency, and dynamic binding, inside the programming language. […]

Date Thursday 14th July @ 14:00 – 15:00 (UK time) Presenter Subarna Chatterjee Affiliation Harvard University Location [Online] Meeting link: Abstract We present a self-designing key-value storage engine, Cosine, which can take the shape of the close to “perfect” engine architecture given an input workload, a cloud budget, a target performance, and required cloud […]

Date Thursday 16th June @ 11:30 – 12:30 (UK time) Presenter Marios Kogias Affiliation Imperial Location [Physical] TBA [Online] Meeting link: Abstract Online services play a major role in our everyday life for communication, entertainment, socializing, e-commerce, etc. These services run inside datacenters under strict tail-latency service level objectives.
