[mpich-discuss] an error in install mpich( HYDU_sock_is_local (/home/mpi/mpich-3.2/src/pm/hydra/utils/sock/sock.c:532): gethostbyname error on mpi1: Host name lookup failure)

Yes i had got that problem during execution
What you are using rsh or ssh?
As i was using rsh and using it i execute as
mpiexec -launcher rsh -f machinefile -n 3 ./a.out
a.out is executable file or object file after compilation
