The effective usages of computational resources are a primary concern of
up-to-date distributed applications. In this paper, we present a methodology to
reason about resource usages (acquisition, release, revision, ...), and
therefore the proposed approach enables to predict bad usages of resources.
Keeping in mind the interplay between local and global information occurring in
the application-resource interactions, we model resources as entities with
local policies and global properties governing the overall interactions.
Formally, our model takes the shape of an extension of pi-calculus with
primitives to manage resources. We develop a Control Flow Analysis computing a
static approximation of process behaviour and therefore of the resource usages.Comment: In Proceedings FOCLASA 2011, arXiv:1107.584
