I have only one cuda version installed.
However it may be that I don't have the correct nVidia module for 2.2 -
right now I'm using 180.44 - I guess I have to switch to the new version,
i.e. 185.18.08 'beta'
As 180.44 worked all right with pycuda 0.93 beta I assumed this was all right
but I was probably wrong then - I assume only the new driver libcuda.so has the
"cuMemHostAlloc" symbol. Sorry for the noise.
Thanks (for your answer and for pycuda - great tool !),
Vincent
