How do I get 100% cpu utilization on single program

[Guest]

I'm running XP Pro (Pentium 4 3.8Ghz) and have only one application running.
I would like to maximize clock cycles on this program so I have the
performance option set to favor "programs". However, I only get ~50%
utilization as seen from the task manager. (Same for all the other PCs I've
had). Is there some way to tell the o/s to apply more cycles (e.g., 100%) to
this one production program.

This processor should have HT, meaning it acts like it has two CPUs.
Unless the program you are running is compiled to run with multiple CPUs
it will only utilize one of them. If you open Task Manager and select
One graph per CPU it should show one of them running at 100% and the
other just idling along. I like the HT as it allows me to run one task
at full speed while still having access to my computer.

Thanks for the help. I see that you can see the the CPU usage of each always
sums to about 100%. I wasn't aware of that even though I've used the task
manager extensively.

You can start your program with a command like:

cmd.exe /c start /high Nero.exe

For extra CPU cycles

or

cmd.exe /c start /Realtime Nero.exe

To maximize cycles.


These commands can be saved as a batch file and used to start the program.

You could also go to Task Manager | Processes and right-click the programs
process and click on "Set Priority" from the menu that appears.
