How do I increase CPU usage for a specific process in Win 2K?

Hi,

I've got a weird situation here. I'm running a program on one of the office machines that is very heavy on mathematical calculations. I also have it on my onw computer. When I run this program on my computer it will use up any available CPU so that in the task manager my CPU is always being used 100%. On the other computer (which is faster better than the one I'm on now) It will only use 50% of the CPU. The other 50% is shown as system idle process. Both computers run the exact same installation of Win 2K.

How can I make it so that it uses all the available CPU? The calculation I ran a few days ago took over 30 hours to complete, so I was hoping if I could get it to use all the CPU it would speed things up.

Answers to questions you'll probably ask:

I have over 300MB of free RAM.
The software is called Luxicon, it does lighting calculations.
I set the priority of the process to real-time (the highest it has)

Any help/suggestions would be greatly appreciated.

If the second computer is Hyperthreaded or a Dual Processor machine, it will show 50% because the program is only using 1 cpu

This is normal. Sounds like you have an HT machine. As such Windows is 'seeing' it as two cpu's. Since your app is single threaded it can, at most, only hit 50% cpu usage. On a HT machine (since you really don't have 200% capacity, more like 115%) you really are maxing that proc out (just taskman isn't really showing it as such)

Ok, I guess that makes sense. i don't know if it is HT, but that would make sense since the TM has two windows for the CPU usage. It isn't a Dual CPU machine.

Thanks for the help!

Having Hyper Threading enabled in Win2K is a little bit hit and miss.

Some applications will get a nice performance boost from it, but others might actually take a perfomance hit, as Win2K isn't optimized for HT like XP is.
