I believe Halide is limited to 2-dimensional (Image Processing) use cases? Either way, it's designed to make it easier to find optimal parallel implementations rather than write code that can fluidly execute across a CPU and GPU.

Well the thing is that it's targeting "x86/SSE, ARM v7/NEON, CUDA, Native Client, and OpenCL."

Anyway, as far as I know it is limited to 2D raster images so far, yes. Since it's part research language with some very interesting features I do hope that it gets extended to more general cases, and at least make it easier to work with 3D use cases (image volumes and such) too.
