Authors: Cheng-Yueh Liu, Po-Yao Huang, Yuan-Di Li

Prerequisite

Ubuntu 16.04

sudo apt-get install docker.io

CentOS 7

wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-18.03.1.ce-1.el7.centos.x86_64.rpm sudo yum install docker-ce-18.03.1.ce-1.el7.centos.x86_64.rpm

How To Execute a Simple MPI Application on Virtual Container Cluster

1. Setup Docker

sudo systemctl enable docker
sudo systemctl start docker

2. Empower Linux Users with tcpdump Tracing on Docker Network Interface

cd clusim
./tools/empower-tcpdump.sh username
tcpdump -i docker0 -w justForTest.pcap

3. Lauch a Docker-based Virtual Cluster and Run a MPI-application

cd clusim/vcluster
docker build -t vcluster .
./start-vcluster.sh 4 0

Then, we will log in to master node (node0)

cd ~ && ./demo-npb.sh bt A 4

Snapshot of Demo

4. Build NS-3

cd clusim/ns3
./build.py 

5. Using Clusim to Simulate and Analyze Network Performance

Modify the path to the logged pcap file in simple.cfg

cd clusim  
make 
cp config/default.cfg .
./clusim default.cfg
