Shell Programming and Scripting

Hi all
I was wondering if its possible to write a script to keep CPU usage at 90%-95%? for a single cpu linux server?

I have a perl script I run on servers with multple cpu's and all I do is max all but one cpu to get into the 90'% utilised area. I now need a script that raises the CPU to 90-95% for 15mins on a server with a single cpu.

Sorry, I should add it needs to be at that level for 10-15mins

Run one instance for each CPU.

You could also try something like mprime

I've updated my original post to provide further clarity

download the stress utility

Use this as a reference.

Linux Stress Test - memory, disk, and cpu testing with StressLinux

well thanks for your advice all but I ended up using

Code:

perl -e 'while (--$ARGV[0] and fork) {}; while () {}' $NUMBER_OF_CPU &

but i re-niced the process until cpu was at 90-95%
