Thank you very much. After that I try with the mpirun: [guser1@ioitg2 examples]$ /opt/openmpi/bin/mpirun -np 10 --hostfile myhosts ring_cxx gus...@node1.ioit-grid.ac.vn's password:gus...@node2.ioit-grid.ac.vn<password%3agus...@node2.ioit-grid.ac.vn>'s password:
This request passwd to login to nodes, but 2 massages in the line, I can only success with one node, the 2sd. refussed. So, how I can do as you advise, to login to each node without being prompted for a password. ? What I need to do. Help me. I run openmpi 1.2.9 supporting SGE (when I buil with --with-sge). I had tested to buil with 1.3. or 1.4. with this option I saw the error no recognize --with-sge. Why ? bug or ? While docs README shows that this is supported. I need this because I run SUN gridengine on may cluster. You have some ideals ? Thank you very much. Sincerely.
