Abstract
Modern architectures are becoming more heterogeneous. OpenMP currently has no mechanism for assigning work to specific parts of these heterogeneous architectures. We propose a combination of thread mapping and subteams as a means to give programmers control over how work is allocated on these architectures. Experiments with a prototype implementation on the Cell Broadband Engine show the benefit of allowing OpenMP teams to be created across the different elements of a heterogeneous architecture.
