Intall mpich2

1. Testbed Introduction

• VMware Workstation 5.0
• Create three nodes, client-01 ~ client-03, all with 5GB HD and 128MB memory.
• The OS on these 3 nodes is Ubuntu-7.10-server
• hostname and IP are:
  • client-01 192.168.180.131
  • client-02 192.168.180.132
  • client-03 192.168.180.133

2. Getting Start to intall mpich2

• Step 1 : Modify /etc/hosts
  • Assume that we got 3 machines in our testbed, now we have to edit /etc/hosts on each node.
    Here is the example of client-01. So does the other two nodes.

    root@client-01:~# cat > /etc/hosts << "EOF"
    > 127.0.0.1 localhost
    > 192.168.180.131 client-01
    > 192.168.180.132 client-02
    > 192.168.180.133 client-03
    > EOF
    

  • Check the /etc/hosts contents, it should be like this.

    root@client-01:~# cat /etc/hosts
    127.0.0.1 localhost
    192.168.180.131 client-01
    192.168.180.132 client-02
    192.168.180.133 client-03
    

  • Notice that if there is 127.0.0.1 client-01 in /etc/hosts, it must be deleted.

• Step 2 : Download and Install mpich2
  • We use mpcich2-1.0.7rc1 for example.

    root@client-01:~# wget http://www.mcs.anl.gov/research/projects/mpich2/downloads/tarballs/mpich2-1.0.7rc1.tar.gz
    root@client-01:~# tar -zxvf mpich2-1.0.7rc1.tar.gz
    cd mpich2-1.0.7rc1/
    

  • You could choose the install location as you wish, but all the nodes must have the same install location!!
    We use /opt/mpich2 here for example.

    root@client-01:~/mpich2-1.0.7rc1# ./configure preifx=/opt/mpich2
    

    • If there are errors when configuring mpich2, you may need some packages or libraries such as c/c++ compiler.
      Try this :

      root@client-01:~/mpich2-1.0.7rc1# apt-get install build-essential
      

  • compile and install

    root@client-01:~/mpich2-1.0.7rc1# make
    root@client-01:~/mpich2-1.0.7rc1# make install
