Compositional Reasoning for Explicit Resource Management in Channel-Based Concurrency

Adrian Francalanza ; Edsko DeVries ; Matthew Hennessy.

We define a pi-calculus variant with a costed semantics where channels are treated as resources that must explicitly be allocated before they are used and can be deallocated when no longer required. We use a substructural type system tracking permission transfer to construct coinductive proof&nbsp;[&hellip;]

A calculus for costed computations

We develop a version of the pi-calculus, picost, where channels are interpreted as resources which have costs associated with them. Code runs under the financial responsibility of owners; they must pay to use resources, but may profit by providing them. We provide a proof methodology for processes&nbsp;[&hellip;]
