I respect that you have other priorities, i can relate on a different level.

>Why should I spend time on a task that I estimate is mostly a waste of time?

You shouldn't if that's what you really think priorities aside, but i wonder how
you can call it a waste of time when 3 of the absolute top programs have SMP
implimented; Junior, Fritz and Shredder. Not to mention the other strong engines
out there which are SMP too...

More strenght (however minute that might be)

This is not the point at all, we simply don't have, Diep running on a single
processor, results from serious competition (not that i know of) therefore there
is no precedence indicating what Diep/Vincent have gained from SMP.

I disagree with Vincent on a lot of issues, but where i agree with him is: a
program that can run single, dual, quad or even 500 processors is more a program
of the future than one that only runs single.

The only thing stopping me from buying Diep is the lack of WB/UCI support!

>How can you justify that it has not been an almost complete waste of time?

How can you justify that compchess in general is not a complete waste of time,
well i am sure that what ignited a spark in you to write a chess program as
great as CT is not far away from the spark igniting Diep as we know it today,
the things we do as humans to create, is a fine line between waste of time and
fulfillment.
