Error while running MPI cluster program in LAN

Getting error while running MPI cluster program in a LAN environment. I have created a master and other clients in a local LAN environment. I follow this tutorial to create a cluster and runs it, Running an MPI Cluster with in LAN

mpiuser@507-12:~/cloud/mpich-3.0.4/examples$ mpirun -np 4 -hosts 192.168.100.77, 192.168.100.78 ./icpi 

mpirun: Error: unknown option "-o" Type 'mpirun --help' for usage.

It's saying that we should use proper tags while writing the command and then it will work. But, I tried many ways to run it by changing or altering the tags. Still getting the same error. Couldn't figure out whats going wrong. Kindly, help me in due respect. Thanks.

The option -hosts should be -host (alias -H, --host)
