We have mostly tested the NVIDIA implementation, but plan to test the
AMD one too.

Did you set STARPU_NCUDA to e.g. 0 and STARPU_NOPENCL to 1, to prevent
CUDA from stealing all the GPUs for itself? (OpenCL and CUDA can not run
at the same time on the same GPU).
Nathalie, I guess that should be documented in starpu.texi, maybe we
should add CUDA- and OpenCL-specific sections.
