Run CPUBurn-in

It may be necessary to chmod the extracted binary to run (or execute the binary with sh):

[root@raldisk ~]# chmod +x cpuburn-in

Note: cpuburn-in should have one running instance per core/virtual core. To achieve this, create a script to calculate the number of available core and run cpuburn-in a sufficient number of times to fully stress the cpus:

START=1
END=`cat /proc/cpuinfo | grep processor | wc -l`

for (( c=$START; c<=$END; c++ ))
do
        nohup ./cpuburn-in 3600 &
done
top

NB - the "3600" above is the number of seconds for the stress test to run.

Ending CPUBurn-in

To kill cpuburn-in manually before the stated completion time, use killall:

[root@raldisk ~]# killall cpuburn-in
