I believe Diep is Deep (pun intended).  I did not know about Patzer being smp
(never tried it).

I suspect  very few know that the (Non Deep) Junior 8 is SMP !!   I have
confirmed 100% CPU untilization on a dual using Junior 8 (via the task manager)
and by nps in DJ in single thread mode vs Junior 8 (J8 nps is nearly double
single threaded D8) .   The difference between Deep Junior and Junior is that
Junior does NOT have a "number of threads" option - it ALWAYS runs in mt=2 mode
on a dual.

Naurally, Junior will get excellent results in all dual machines with pondering
on!.  So for engeine matches on duals, you should use the Deep verson and select
1 thread and NEVER use Junior to be fair!


The $1,000,000 question of course is why does Deep Junior sell for $50 more
Junior when that are both SMP engines - the only difference appears to be the
number of thread options setting.  I have my opinion of course, but if I express
it here, I cound be banned for life from CCC ;>).
