No my viewpoint is that tiger is a too buggy engine to get SMP easily, but we
will never find out, as he's too lazy to even try that. No doubts that you can
work forever at forward pruning and such stuff. With or without SMP.

But if you first get a near to factor 2 faster with SMP with some effort then
you have your hands free too, to toy there. You do not make up for a factor 2
simply with the same engine.

Nowadays new chips have SMT too. Within a few years that will work better on
coming cpu's than it does now. perhaps amd even will get it one day. that would
be awesome.

But Tiger will be still single cpu then most likely, which is a shame for such a
good engine.
