This report describes how to use the provided script to profile NFD performance
|
|
on ONL (https://onl.wustl.edu/) using Callgrind.
|
|
|
|
Assumptions
|
|
===========
|
|
|
|
This report assumes that users have an ONL account. If you don't have an account
|
|
yet, please refer to the ONL official website to apply.
|
|
|
|
|
|
Experiment Steps
|
|
================
|
|
|
|
1. Login on the onlusr machine:
|
|
ssh -L 7070:onlsrv:7070 <your_account>@onl.arl.wustl.edu
|
|
|
|
2. Run RLI
|
|
Open the topology file, and make reservation; if it is not successful,
|
|
change the reservation time, and try again
|
|
|
|
When your reservation is ready, commit.
|
|
|
|
3. Experiment Environment setup
|
|
ONL does not allow us to install programs, this section describes the process
|
|
to compile NFD code on your experiment nodes.
|
|
|
|
(1) clone script on onlusr
|
|
|
|
git clone https://github.com/WU-ARL/NFD_Performance_Testing_on_ONL.git
|
|
|
|
(2) Log on to one of the pc2core experiment nodes
|
|
|
|
In RLI, you can see the nodes name. Just choose one, and ssh to it.
|
|
|
|
(3) Compile and install ndn-cxx in your home directory. And then the NFD code.
|
|
|
|
The scripts make it pretty easy to do so. The README in scripts explained it clearly.
|
|
Here we just point out the main steps:
|
|
|
|
A. in NFD_current_git fold, run “./git_initial.sh”.
|
|
This script would download the latest code repository to your current directory.
|
|
|
|
B. run “./build_all.sh —profile”
|
|
build_all.sh compiles with “-pg” and installs the ndn-cxx and NFD in the usr folder
|
|
of your current directory.
|
|
|
|
(4) script modification
|
|
|
|
|
|
|
|
NFD Testing
|
|
===========
|
|
|
|
1. logout the pc2core node. cd to the Variable_Length_Names folder.
|
|
|
|
2. run mkAll.sh to configure the experiment
|
|
|
|
Usage: ./mkAll.sh [options] <count> <proto> <interval> <num name components> <component length>
|
|
Options:
|
|
[--local] - use start scripts to run local (../NFD_current_git_optimized/usr/local/bin/) versions of nfd and nrd
|
|
[--installed] - use start scripts to run the installed (based on PATH) versions of nfd and nrd
|
|
|
|
e.g. ./mkAll.sh --local 64 udp4 8 5 5
|
|
|
|
3. start the experiment: ./runAll.sh
|
|
|
|
4. stop the experiment: ./killAll.sh
|
|
|
|
Another script is provided to simplify the experiment: “seriesTest.sh”. You can modify it
|
|
to make your work easier by changing the parameters.
|
|

|
|
Check Result
|
|
============
|
|
|
|
Since we use gprof to generate the results, you need to save the report gmon.out to another place
|
|
and rename it.
|
|
|
|
Please refer to the gprof manual to generate the result
|
