What is warping in the context of OpenCL?

I am sure that deformation is defined only in CUDA. But maybe I'm wrong. What is a warp from an OpenCL perspective?

This is not the same as a working group, is it? Any relevant feedback is much appreciated. Thank!

It is not defined in the OpenCL standard. Warp is a hardware-executed thread (CUDA threads are not actually threads and are displayed on warp as separate SIMD elements with some smart hardware / software mapping). This is a set of work items, and there may be several biases in the work group.
