Standard? I can only think of 3 commercial programs that support SMP: Deep
Fritz, Deep Junior, and Deep Shredder. Unless they represent the majority of
commercial programs they do not constitute a standard IMO. DF is a special case
as it is not simply an SMP version of Fritz 6, but an upgrade of it. As to the
other two, I somehow doubt their SMP versions outsold their single-cpu versions.
Multi-cpu machines are very far from being the standard, and while they may
certainly be accessible (pricewise) in some countries nowadays, they are a very
very small minority. Most people think in terms of more MHz or GHz as opposed to
more cpus.
