What do you mean? n_expert_used views followed by n_expert_used - 1 adds

Well, it's a little awkward when n_expert_used is 1 (ie, no add, but cont instead), and I'm not sure you're catering for that?

Good point, I'll fix that once I figure out the other problems in this kernel (namely related to the lifetime to the weights buffer)

This kernel causes some weird perplexity behavior which I can't explain. I will need to fix it before adding it back again
