Thank you, i m reading up on de tools u suggested. I am facing another problem, my cluster is working fine with 2 hosts (1 master + 1 compute node) but when i tried 2 add another node (1 master + 2 compute node) its not working. it works fine when i give de command mpirun -host <hostname> /work/Pi
but when i try to run mpirun /work/Pi it gives following error: root@192.168.45.65's password: root@192.168.67.241's password: Permission denied, please try again. <The password i provide is correct> root@192.168.45.65's password: Permission denied, please try again. root@192.168.45.65's password: Permission denied (publickey,gssapi-with-mic,password).
