Subject: Using a dual processor system

Author: Gordon Rattray

I'm considering buying a dual processor system (dual PIIIs).  What sort of
things should I be aware of?  Here's my thoughts...

- I presume that at the moment I can only run Deep Junior in order to use both
CPUs for the one engine simultaneously.  Does DJ achieve 1.8 efficiency while
using a dual system?  Are there other distributed engines available?

- within the Fritz interface, I expect to be able to use multiple kibitzers and
benefit from the dual CPUs.  Assuming there is enough memory, is this equivalent
to having two separate machines each with one of the CPUs?

- for the "compare analysis" functionality, and selecting Fritz, Junior, Nimzo,
etc., will I benefit?  Or do I need to run two instances of the interface?

- I should be able to support engine matches/tournaments with pondering on.


These are some of the things I've been thinking about while considering a dual
processor system.  Although I have other motives, e.g. running a multi-threaded
compiler, I'd like to know more about using it for chess programs.  I'd
appreciate any comments/advice on this.
