TubeTK/Code Optimization in Linux

The following script demonstrates profiling on linux using oprofile

• OProfile Web Page: http://oprofile.sourceforge.net/about/
• You can download the following script from this link: File:TubeTK OProfileExampleScript.txt

#! /bin/bash

# notes:
# opcontrol: controls data collection
# opreport: retrieves profile data
# opannotate: produce notated source code

# configure
opcontrol --no-vmlinux
opcontrol --callgraph=6
#opcontrol --event=CPU_CLK_UNHALTED:100000:0:1:1
#opcontrol --event=CPU_CLK_UNHALTED:1000:0:1:1
opcontrol --event=default

# TODO: could potentially increase count = number of samples to take

# start opcontrol
opcontrol --reset
opcontrol --start

# run the test
