Thanks for the swift reply! But the ratings difference of three times the speed
is probably (almost certainly) not even in the neighbourhood to a hundred
points. And another complicating factor is that parallel search can in many
cases be less speedy than a single cpu for example a 1GHz processor running the
same program as a say 4*1GHz processor might finish first to the same depth as
the supposedly faster parallel search (faster but way less efficient). True
there is a hardware advantage in SMP, but it's debatable if it is enough to
guarantee hardware/software supremacy. Now that I think about it, there is a
hidden advantage in parallel programs: they are non-deterministic and therefore
less prone to repeat any home preparations. A small advantage but still:) I
think the planned matches will be fun in any case.
