Alain, Erik -

Nice work indeed!

This might also be 20% of your CPU, without the GPU involved.  Notice
how the real c/s rate is roughly 19% of the virtual one, which confirms
this guess.  Real is what you actually get; virtual is what you would
presumably get at 100% load of one CPU core (and, from your non-OpenCL
benchmark, you know that you could get even more than that).

Yet it is nice to see that we have "something" working, even if it
performs so poorly at this early stage.

Thanks,

Alexander
