[mpich-discuss] Passwords on small cluster

Dear all,

I am trying to run my mpi job on a small cluster with 5 nodes. When I run

mpirun -n 5  --host node01,node02,node03,node04,node05   ./hesp

the system requests a password for node01.

if I run the job only on node05 then no pasword is requested and the job
runs OK Is there some way I can include a password in the host file, or
otherwise ?
