Periscop suite aggregates a set of tools and libraries for using the polyhedral model (or polytope model) in an optimizing compiler.

Polyhedral model uses an algebraic representation of imperative program statements and control constructs to provide deep analysis and enable agressive restructuring. From the very high-level point of view, iterative executions of program statements are represented as points in a multi-dimensional space that form a polyhedron, hence the name of the model. This representation was initially available only for static control flow regions, commonly referred to as SCoP, Static Cotrol Parts. Thus “periscop” stands for tools “around static control flow parts”.

The suite currently contains the following projects:
