Settings and software

Our cluster is based on this tutorial: https://help.ubuntu.com/community/MpichCluster

However, we have the following additions/exceptions:

1) To find IP addresses for nodes, log onto the node and type the following command: ifconfig

Then look for the inet addr in the eth0 section.

1) When prompted to give an SSH-passphrase, leave this field blank.

2) In all nodes change etc/ssh/ssh_config to have the following line:

   Port 41122

3) In all nodes change etc/ssh/sshd_config, add the following line:

   Port 41122
   PermitRootLogin no (NOTE: this should replace the line which previously said "PermitRootLogin yes")

4) Before installing MPICH2, run the following commands:

   sudo apt-get install build-essentials gfortran gfortran-multilib autoconf
