The current trend towards multi-core/manycore and accelerated architectures presents challenges, both in portability, and also in the choices that developers must make on how to use the resources that these architectures provide. This paper explores some of the possibilities that are enabled by the Open Computing Language (OpenCL), and proposes a programming model that will allow developers and scientists to more fully subscribe hybrid compute nodes, while, at the same time, reducing the impact of system failure.
