[mpich-discuss] error in ssh

[Eugene N]

Hello

Building a cluster consists of two main steps
1) set up the network
2) set up mpi-related stuff

During the 1 stage you must edit /etc/hosts to include hostname resolutions
for all your nodes, dont forget to check etc/host.allow! and you should set
up an ssh server on each node (passwordless)
with authentication using public keys(quite a procedure). Oh, and you should
have one user account (same name) on all machines.

Then, before moving to stage 2, you should check whether you can ssh to
every machine. If you can, and its ok, then write down mpd.hosts (in ~/ on
each node)
the file should include all hostnames except the current one.

Use mpdcheck, mpdtrace to troubleshoot, as written in mpich2 manual.

Good luck
Eugene
