Introduction

Francois Bodin, CAPS Enterprise

The GPU Club welcomed Francois Bodin, CTO of CAPS, talking on Programming Heterogeneous Many-Cores using Directives

Fran├žois discussed a directives approach to programming GPUs and their HMPP Workbench product. HMPP is a GPU and many-core programming environment. HMPP enables portable programming across GPUs and multi-core CPUs using directives similar to OpenMP, removing a lot of the complexity associated with programming GPUs.

Abstract

Directive based programming is a very promising technology for dealing with many-core architectures. Emerging standard such as OpenACC are providing a solid ground for users to invest in such paradigm.

In this presentation we present this technology using OpenACC and HMPP directives as well as companion tools (e.g. for tracing and tuning, for debugging): HMPP Wizard(1), CULA(2), ArrayFire(3), Vampir(4), Paraver(5), Allinea DDT(6), CodeletFinder(7) etc.

We show how code migration and tuning can be performed and how machine specific features such as NVIDIA UVA can be used. We describe how accelerated libraries can be integrated seamlessly into applications. Finally, we address advanced issues such the integration of auto-tuning techniques into applications as well as inter-operability to parallel runtime libraries such as StarPU(8).
