Need Script to Use CPUs on a HPUX server to simulate Workload Manager on HPUX.

I am running HPUX and using WLM (workload manager). I want to write a script to fork CPUs to basically take CPUs from other servers to show that the communication is working and CPU licensing is working. Basically, I want to build a script that will use up CPU on a server. Any ideas?

The mpctl() system call (in C) lets you specify what cpu a process runs on.
Is that what you meant?

or something like this?
Code:
i=0
while true
do
    while [[ $i -lt  100000000 ]]
    do
         i=$(( $i + 1))
    done
    i=0
done

This is BAD idea on a production system with other users, especially if you start a bunch of these running.

Hi Jim - I ended up using something similar.

Code:
#!/sbin/sh
for i in 1 2 3 4 5 6 7 8 9 10
do
        while `true`
        do
        false
        done
done

I agree not the best idea but I needed to test.

Thank you.
