Overview

Reference Overview

The AllScale API provides two important concepts for achieving large-scale parallel performance:

• data structures that are distributed-memory-enabled
• parallel operators that offer efficient means of performing common operations in parallel

Data Structures

Name	Description
Grid	Regular n-dimensional array, size defined dynamically at creation
Bag	Unordered container (also known as a multiset)
Mesh	Multi-layered representation of a graph structure with multiple node and edge types

Parallel Operators

Name	Description
Pfor	Iterates over a given range of elements and applies a given function in parallel
Stencil	Iteratively applies a given update function to an n-dimensional array of elements in parallel
VCycle	Iteratively applies a given update function on a mesh in a multi-grid fashion
