This is absurd. Did you just coin the term "SMP search" to win this argument?
Please give the URL of some paper with this term in it. SMP is a type of
computer. You might as well say that you also invented "486 search." Either a
search is distributed over multiple processors or it isn't. Granted, some
implementations fit particular hardware better than others, but to disqualify a
program for that is crazy. Imagine this conversation:

Tom: Is Zugzwang SMP?
Feldmann: No, it just searches using all the processors in an SMP machine.
