Program Transformation to Identify List-Based Parallel Skeletons

Program Transformation to Identify List-Based Parallel Skeletons

Blog Article

Algorithmic skeletons are used as building-blocks to ease the task of parallel programming by abstracting the details of parallel implementation from the developer.Most existing libraries provide implementations of skeletons that are defined over flat data types such as lists or arrays.However, skeleton-based parallel nacrack.com programming is still very challenging as it requires intricate analysis of the underlying algorithm and often uses inefficient intermediate data structures.

Further, the algorithmic structure of a given program may not match those of list-based skeletons.In this paper, we present a method to automatically transform any given program to one that is defined over a list and is more likely to contain instances of list-based skeletons.This facilitates the parallel execution of a transformed program opi the color that keeps on giving using existing implementations of list-based parallel skeletons.

Further, by using an existing transformation called distillation in conjunction with our method, we produce transformed programs that contain fewer inefficient intermediate data structures.
