An adaptive methodology for multi-GPU programming in OpenCL

Abstract

PurposeThe 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/approachA methodology for auto-tuning OpenCL configuration parameters has been developed.FindingsThis described process helps simplify coding and generates a significant gain in time for each method execution.Originality/valueMost 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.
