Does anyone know where I can find a PowerPC CPU stress test? I have came across many Linux CPU stress test but none of them seem to support PowerPC.

You can just open a terminal and enter:
That will run your CPU at 100% until you ctrl-c to kill it. It's a good way to check that temperature monitoring works and fans turn on, for example.

Great! Thanks I'll give that a try. I'm trying to test CPU power consumption under full load.

If you would like to stress your CPU with a heavy load , my below script would do more than you want.

excute the below script on your power pc system:

# cat cpu-online-offline.sh
#!/bin/bash
LIMIT=7
RANGE=7
randnum=0 #initialize random number

function cpuhotplug {
N=$1
result=`cat /sys/devices/system/cpu/cpu${N}/online`
if [ $result -eq 0 ]; then
echo 1 > /sys/devices/system/cpu/cpu$N/online
fi

while : #do cpu online offline infinitely
do
echo 0 > /sys/devices/system/cpu/cpu$N/online # online cpu
sleep 5
echo 1 > /sys/devices/system/cpu/cpu$N/online # offline cpu
done
}

while [ $randnum -le $LIMIT ]
do
randnum=$RANDOM # Generate random number
let "randnum %= $RANGE" # Scales $randnum down within $RANGE.
x=1

cpuhotplug $randnum &

done


NOTE: This script will generate heavy load on cpu and memory too ...script is a fork bomb so oom is expected.
But it can hit real kernel issue.With my script cpusets (and sched domains) are updated asynchronously during hotplug via worker threads.
And it does by asynchronously , where you have plenty of pending hotplug operations on each cpu, at almost any given point in time.


Thanks...

This may compile on PPC, possibly:

I don't have PPC, so I don't know.

Some info here. Dunno if this would compile on PPC also.
