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 ?
You will have to set up some kind of passwordless access, either by a passphraseless SSH-key (if you are the only user), or hostbased authentication (to make the setup one time for all users). https://www.open-mpi.org/faq/?category=rsh#ssh-keys (although this page is from the Open MPI site, the constraints are the same as in MPICH) or: https://arc.liv.ac.uk/SGE/howto/hostbased-ssh.html -- Reuti PS: You could also use an SSH-agent http://www.unixwiz.net/techtips/ssh-agent-forwarding.html which will answer all further requests for the passphrase after you entered it one time. _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
