You could for instance watch the video that is on the starpu website,
which provides some insight into the structure of StarPU.

It's in between: it uses low-level drivers (OpenCL, CUDA) and manages
tasks submitted by higher level (e.g. OpenMP tasks).

Basically the Inria Storm team (www.inria.fr/equipes/storm) nowadays,
and previously the runtime team (https://runtime.bordeaux.inria.fr/)

The starpu website shows a list of projects using it.
