Editing HPC High Processing Cluster in IIT DELHI (section)

=='''Preparation of slave nodes'''==

a. beowulf and wolf user were created as in master node

b. Edit file /home/wolf/.bash_pofile


export LAMRSH='ssh -x'

ssh-agent


MPICH2=/usr/local/mpich2

PATH=$HOME/bin:$MPICH2/bin


Make /shared directory

mkdir shared


c. Create entry in /etc/fstab/


master_node:/shared /shared nfs rw,hard,intr 0 0


This will mount the nfs shared drive at boot time


c. Reboot all the nodes.

d. login as wolf users and install MPI as described above in MPI installation section.


'''Note''': Firewall should be disabled in all nodes as MPI uses randoms ports each time it is started.


“mpdboot -n 5 -f mpd.hosts” command should be executed as root user from master node. This will start mpd daemon in slave nodes 


First master node must boot then slave node so that nfs share are mounted on slave machine.


2 . Finally we installed the IIT application “Fluent” on to the shared directory /shared which is shared by all nodes too. Mdp daemon has to be started on all the nodes as mentioned above and then only master node as user wolf can start the application.
