Anybody running LabVIEW 7.0 on a Pentium II?

last year i runned it on a pII computer, but i didn't use it for acquisition, it runned just a simple motor.

Hi Ed,

LabVIEW has supported Multithreading on Multithreaded OSs since LabVIEW 5. At the same time support for Multiprocessing was added.

Please refer to the following link for much more information on Multithreading, Multitasking, Multiprocessing and Hyperthreading:

Here is a link to the Matrox G400 Spec.. It seems that they do hardware support for OpenGL. I don't know if the OpenGL library NI uses will make use of it. But if you like and know C you can look at it. The sources are located on your LV installation CD as it is required by GNU public license.

Philip,

So the development evvironment is dual processor aware and can take advantage it? The question I was trying to figure out is, "Does a dual processor machine help during development, or only when your applicaiton is running(if it's written correctly)".

Thanks
Ed

Hi Ed,

You got me! All the documentation I can find on multithreading refers to the running VIs and not the actual Development System. I will have to get an answer from our R&D department regarding this question.

I'll get back with an answer ASAP.

I think I'm gonna start a new thread about this.

I'm back with an answer from R&D:

In the LabVIEW Development System everything at edit-time is single threaded and runs in the UI thread. This is chosen because you generally wouldn't get much gain from the editor running in multiple threads, even on a multi-processor machine.

I will create a KnowledgeBase that describes this behavior, in case the question should arise again later.

Thanks.

And it's really interesting.

Thanks Phillip,

Another useful bit to file away.
