Multicore architectures require parallel computation and explicit management of the memory hierarchy, both of which add programming complexity and are unfamiliar to most programmers. While MPI and OpenMP still have a place in the multicore world, the learning curves are simply too steep for most programmers. New technologies are needed to make multicore processors accessible to a larger community. The signal and image processing community stands to benefit immensely from such technologies. This article provides a survey of new software technologies that hide the complexity of multicore architectures, allowing programmers to focus on algorithms instead of architectures.
