What do you mean by optimized?

Are you saying that you want the reference implementations to be straight

That is a defensible position.  I am just asking.

Can you explain your reasons for this?  Do you think the community would be
less likely to accept HPGMG if they saw a lot of optimized code in the repo?

Do you agree with my statement in my last email that the reference
implementation should be pretty good for a least one platform?  I thought
we were on the same page on this but if not we should do that now.
