SSH ,Hostname,MPI,clustering

I am trying to build small cluster from two laptops,and I was following some tutorial for that purpose, in which they have asked to comment:
" jayesh"(from etc/hosts --jayesh is my username),
but after commenting this statement my MPI executable files are unable to run.
compiled with:"mpicc hello.c"
run :mpirun -np 4 ./a.out
so whenever I removes the comment It runs but on localhost only ,means I cant run the process on cluster.
If anyone have some idea please advice me to get out of the stuk.

What are you trying to cluster? The filesystems? I'm not sure I follow what you are attempting here. Can you post a link to the tutorial you were following?

The link which I followed :ubuntu mpich installation

Also can you suggest me some simple way to run jobs on different nodes of MPI.
(will LAM-MPI help?)
