Amazon AWS machines are not connecting
I have an Amazon AWS account, I have created 4 machines, but in security groups there is no option for outbound, therefore, when I send a ping request it is not forwarding. Any help will be appreciated, how can I connect my machines, I am implementing an MPICH2 cluster.
Solution
