Yeah, I thought it was successful and did a make install and setted the PATH. But when I ran some tests I met some problems and I thought it was due to the step make.
I copied the code from my terminal

dhcp-27-100:mpich-install holmes_conan$ ssh othermachine date
ssh: Could not resolve hostname othermachine: nodename nor servname provided, or not known
dhcp-27-100:mpich-install holmes_conan$ rsh othermachine date
rcmd: getaddrinfo: nodename nor servname provided, or not known

This *looks* like examples of testing connectivity: 'ssh othermachine date' should try to execute 'date' on the machine named 'othermachine'; you likely need to replace othermachine with the name of the other machine you're connecting to; or localhost if you're just using one machine (ie testing that sshd is running & accepting connections, likely trying to make sure it's working passwordless.)

The two commands above and their responses have nothing to do with mpich's installation state.
