Tom,

I'm getting a lot of brouhaha about the new dual system I
have...let's go to the source...IP is multi-threaded...is it also
multi-processor enabled, or am I in one of those "vague areas" again?
Mike's reply has the answer:

Being multi-treaded allows "Windows to decide which processor" to use
meaning it can utilize multiple processors. So
you are going to get some bang from your multiprocessors! I'm jealous!

IP was initially designed to be multi-threaded. The IP code issues a
BeginThread() function and Windows decides which processor will run
the thread. Currently compute intense commands such as all of the
iterative restoration methods, adaptive histogram modification,
region growing, dilation, and erosion are multithreaded. Operators
that are multi-threaded diaplay a yellow frame around an image while
the operation is executing and also have a Cancel button to stop the
execution. If the Cancel button is used the current iteration is
finished before control is returned to the operator dialog box.

I'll do it on 2 conditions:
1) Send me boxes of Oreos™ and cases of Bass Ale®
2) Get me Cindy Crawfords address.

TD :)

p.s. Oh...and throw in a few does dozen Titleist Tour Balatas.

Tom,

One thing you can do is do a CNTL-ALT-DEL and open up task manager. It will
show you the load on your two processors. Then do something in different
applications and see what happens. At least this worked in NT and 2000. If
you are running XP I am not sure.

Bob

Thanks, Ken...I remember that response, but I'm currently in a "chat"
where the thinking is multi-threaded does not necessarily mean multi-
processor enabled.....

To me, in my mainframe mentality, if its a single-threaded app on a
multi-processor, you get single threaded service. If its a multi-
threaded/processor app running on a single processor, you get single
threaded service. If its a multi-threaded app running on a multi-
processor, Hello Dolly!

Not sure if I'm getting caught up in the nomenclature, or its my real
slow leak, but it gets a tad frustrating when you get 17 different
answers to the same question where, in theory, I'm expecting maybe 2
or 3 that may be diverse, but not by much.

Thanks :)

That's a thought. Right now, the box is sitting idle with just the
OS loaded until I can get a new vid card. No sense of
tailoring/migrating until I'm comfortable with the config.

The g/f is a client/server/network tech and I'm sure we'll be doing a
lot of benchmarking. Hmm...just brought up task manager and it looks
like its showing 2 distinct CPU usage graphs.

I haven't touched 2k or XP and just ever so slightly played around
with NT, so its a learning curve. Its an OS, so there's *some* hope
for moi!

Thanks to all for the input, and by all means keep it coming!
