Looks very interesting :) but I can't quite find out what is going on on the GPU. What GPU operations are executed for a sample program which contains various (scalar, vector, applying to different sizes and shapes etc.) operators?

Any array combinator (most importantly map, scan, reduce, and filter) are executed on the GPU (or whatever parallel execution platform is used).

What is the minimum OpenCL version? I'm evaluatimg if this could be a viable experimentation for parallelizing task which uses amazon GPU compute which are mostly nvidia GPU.

Somewhere around OpenCL 1.1 and 1.2. It works fine on NVIDIA GPUs - they are our main test platform.
