# Name:        LoadScript.ksh
#
# Description: Generates CPU Load on a Unix Machine.  This will load a CPU for a given number of loop cycles
#              as defined by the variable "num" before sleeping for a given number of seconds as determined
#              by the sleep value.  The script will continue this load, sleep loop until killed.
#              Alternatively, if the sleep parameter is hashed out the script will stress a CPU to the max
#              continuously until killed. This script can be very useful in a testing environment to
#              see how a machine/application behaves under load.
#
# Usage:       Called by RunLoadScript.ksh
#
#
#
# Create an infinite outer Loop
#

while :
do

#
# Set the number of loop cycles
#

integer num=200000

#
# Create an inner loop and stress the CPU for the defined number of loop cycles.
#

while (( num ))
do
   (( num = num -1 ))
:
done

#
# Set a sleep value to give the CPU a rest or hash out to stress the CPU to the max.
#

sleep 5

#
# End Outer Loop

# Name:        RunLoadScript.ksh
#
# Description: Submits X number of LoadScripts.kah as defined by variable num. Variable num should be set to the number of CPUs/Cores you wish to
#              load.  Note:  The script will swap from CPU to CPU.
#
# Usage:       Used to submit LoadScript.ksh.  Terminate all submitted processes using pkill <procid>
#
#
#
# Set num to the number of CPUs/Cores.
#

integer num=64

#
# Submit a LoadScript for each CPU/Core.
