I need two computers.

[Dave_L]

My productivity would go way up on large assemblies if I had two computers.

You can tell by the frequency of my posts as to how large my assembly is. The bigger the assembly, the more time to educate myself in this forum.

Been there, done that. I had 2 at my old job. They were hooked together
with an iogear KVM switch, both networked and shared. It worked extremely
well - especially with the 10+ minute tweaks in ipn files...

Reminds me back back in the early days on a 386-16MHz I used to have 3 or 4 going at once in the lab.

I've been using 2 monitors for one computer and it works great. I'm just
wondering how IV runs on 2 computers? Do you mind to explain?
Thanks, Chris

it does ok if files are stored over a network. I have two PCs at my desk (one new and one old). I'll do most work on the new, but if it is cranking away on something, I'll fire up IV on the other and keep working (not on the same file of course).

I don't know about distributed computing with IV (1 app, multiple processors).

Before convincing my boss to have 2nd computer on my desk, I need to
understand how it works. Anyone here please?
Thanks

You need 2 computers, 2 seats of IV. When 1 machine is busy (100% CPU), you
use the other machine to work on something else.

Would that work with a dual CPU system, like the Athelon 64/2 units now being shipped?

AFAIK, a user cannot selectively use one processor or another on a dual processor motherboard. However, Inventor may or may not use the two processors, depending on the software libraries and operating system. Most likely you would see a performance increase by having a two CPU motherboard, although the increase will not be linear (2x CPU does not mean 2x as fast, maybe 1.5x as fast or even 1.2). The user (or even programmer) shouldn't have to worry about the two CPU's though, cause the load balancing is taken care of by the low level OS.


Cory is referring to having two seperate machines side by side and using Inventor on both. Each computer is running a seperate instance of the Inventor application.

Actually, in W2K, M$ has an applet that allows you to assign an "affinity" to an application to run on a particular processor. The question is can you run inventor more than once at the same time on a machine? I think I remember some people claiming that they do that regularly.

Anybody certain about this?

Sure you can. I used to do it occasionally, generally when I need to check
something in a different project. If I remember correctly, when you change
the project file, and then close both sessions (no matter which order) the
next time you start it will be set to the one you changed to. It might work
slightly different than that, but .....

Josh,

I once did a time study to prove the speed difference of IV on a dual machine. Attached is an excel file of the data zipped up with an image of the assembly I used to time the machines. The increases you stated are not far off, my data shows about:

Opening an assembly - 1.6x faster
Placing a an assembly into a presentation file - 1.5x faster
Placing a drawing view of the assembly - 1.4x faster

It should also be noted that this was done in an early release that I believe was supposed to have been multi threading (maybe IV7?).

[TGPE]

So, a new motherboard with a 64/2 processor, a BUNCH of RAM, and you're all set to go, with only one license of IV. Of course with that rig, you might not be waiting as long for the process to clear, but still........................

But for current releases Autodesk says IV is not multi threaded. So,
I would not expect much of a performance increase from a second CPU.

You could benefit if you run another demanding application like ACAD
or a second IV session. I just don't know how smart Windows' load
balancer is in distributing those over the processors available or
whether you can influence that. And I don't know whether Windows can
move a process from one CPU to the other while it is running.

You are probably right, if I were to run the test today my results would be different. However, this proved my point when I needed it to and made our IT dept set my workstation standards to be dual processors.
Even without IV using this extra power, all my others task benefit from it.

Anyways, two processors are (almost) always better than one. And even
if they are not they make you feel better.

And with the new dualcores it is getting cheaper than it used to be.
