Dual Processor?

Hi,
What are the benefits of dual processors? What can they help with if
used? Is there a program that will switch to the other processor when
using two, if one fails?
Thanx

Duel processor systems are for people with lots of money who have
unique processing needs. They are notoriously unstable, and certainly
not something a first time computer builder should even consider. My
friendly advice, steer clear... at least for now.

Dual processor systems are for use in high-intensity, multithreaded
applications that are specifically programmed to utilize multiple
processors. An example would be many of the high end video editing
suites, CAD/CAM programs, etc. etc. that use huge number crunching.
Also, servers profit from multiple processors - they can handle more
traffic with more processors (and the right server software).

For an individual user, dualies are a waste unless you've got a
specific application you know uses multiple processors. Most
consumer-level programs can't access a second processor; no games that
I know of, no entry-level video or photo software can. A dualie
running Word and Windows Explorer is like driving a Porche to the
corner store - it's fun, but it's really unnecessary.

Another issue is the operating system - Win2K and XP are
dual-processor aware, but the older ones are not. I've heard that if
you're running a lot of different programs simultaneously you get a
bit of a performance increase, but it seems like a lot of money for
minimal returns. The actual gain in performance is in the 15-33%
range, last time I heard (tomshardware.com, I think, 2001?).

Maybe in the future, as Intel's "hyperthreading" P4's (kind of a dual
processor processor) get more common, there'll be an increase in
programming for dual processors... but probably not soon, IMHO.

And no, the second processor is not a failsafe - if you want that,
you'll have to get into some seriously expensive equipment..... Both
processors are used at the same time in a dual system.
