An adaptive methodology for multi-GPU programming in OpenCL

Abstract

Purpose

The purpose of this work is to present a methodology that harnesses the computational power of multiple graphics processing units (GPUs) and hides the complexities of tuning GPU parameters from the users.

Design/methodology/approach

A methodology for auto-tuning OpenCL configuration parameters has been developed.

Findings

This described process helps simplify coding and generates a significant gain in time for each method execution.

Originality/value

Most authors develop their GPU applications for specific hardware configurations. In this work, a solution is offered to make the developed code portable to any GPU hardware.
