The theory of cut-free sequent proofs has been used to motivate and justify the design of a number of logic programming languages. Two such languages, λProlog and its linear logic refinement, Lolli [12], provide for various forms of abstraction (modules, abstract data types, higher-order programming) but lack primitives for concurrency. The logic programming language, LO (Linear Objects) [2] pr...

In addition to locality, data access concurrency has emerged as a pillar factor of memory performance. In this research, we introduce a concurrency-aware solution, the memory Sluice Gate Theory, for solving the outstanding memory wall problem. Sluice gates are designed to control data transfer at each memory layer dynamically, and a global control algorithm, named layered performance matching, ...

Abstract Models for concurrency can be classified with respect to three relevant parameters: behaviour/system, interleaving/noninterleaving, linear/branching time. When modelling a process, a choice concerning such parameters corresponds to choosing the level of abstraction of the resulting semantics. In this paper, we move a step towards a classification of models for concurrency based on the ...

An automaton with concurrency relations A is a labeled transition system with a collection of binary relations indicating when two actions in a given state of the automaton can occur independently of each other. The concurrency relations induce a natural equivalence relation for nite computation sequences. We investigate two graph-theoretic representations of the equivalence classes of computat...
