I am working on a 8-node network. For convenience, I setup the user
account(says testmpi) and something necessary by telnet(for example, ssh).
When everything is all right, I try ssh every nodes and succeed. However,
it's very weird that I cannot boot LAM up. The error message is about
"LAM cannot write/create file in /tmp ..." After check, I found that a
folder (called lam-testmpi_at_node1.mpi) do not belongs to user/group testmpi
but belongs to something like "505 505". I have modified the ownership
manually but no help!
