looks like you didn't put enough load on the GPU :-)

Argh - the thought crossed my mind a couple of times but I din't act on it - it makes a lot of sense.

Thanks for this and the rest of the advice: I will swap float3 in and see what happens. As for the blocking, I do need to get the stuff out for now ... but I am thinking to follow @notzed (to whom I will reply shortly in more detail) advice and move the loop in the kernel since at the moment I am plotting stuff just to make sure that the logic is correct, so in that case I could use .finish() I guess.

Once again thanks for all the help!
