Good morning, I have been struggling with getting my machines to work as one. I installed Linux mint on all machines, creating the same username and passwords. I also setup a share file through NFS. My first question is, I cannot ssh from the master node, wolf00, to a slave node, wolf01 etc., without entering a password, how can i fix that? i've been through guides, setting up keychains and it is still not working. I would like to start over setting that up. My second question is, during my Beowulf setup, i created a user in the NFS shared folder (/mirror), does it make sense to install MPICH there using the installation guide, or does if have to be installed on just the master node's machine, or all machines? Looking forward to working with you. Regards, Anthony
