Stencil Algorithm Parallelisation

This project explores the parallelisation of Iterative Stencil Loops using different implementations in Java.

Overview

Iterative stencil algorithms are widely used in solving partial differential equations and image processing. This project focuses on parallelising these algorithms to improve performance.

Implementations

• Executor Service: Utilises Java's ExecutorService framework for parallel execution.
• Aparapi: Leverages Aparapi for GPU-accelerated computations.
• Pyjama: Uses the Pyjama research framework from the University of Auckland which utilises OpenMP-like directives to parallelise Java code.

Only the main branch explores the Pyjama implementation, which is under active development.
