Hello, My problem: How can i make gridengine not to use ssh?
Installed: openmpi-2.0.0 - configured with sge support. gridengine (son of gridengine) 8.1.9-1 I have a simple openmpi program 'teste' which only gives "hello world" output. I start it with: qsub -pe orte 160 -V -j yes -cwd -S /bin/bash <<< "mpiexec -n 160 teste >> /home/ljohndoe/out.dat" on the master node. I get back the error: Host key verification failed. Host key verification failed. Permission denied, please try again. Permission denied, please try again. Received disconnect from 192.168.117.6: 2: Too many authentication failures for johndoe Permission denied, please try again. Permission denied, please try again. Received disconnect from 192.168.117.5: 2: Too many authentication failures for johndoe [...] When i configure a passwordless ssh login to the execute nodes (exchanging the ssh key from master with 'ssh-copy-id), it works like charm. So it obviuously uses ssh connection to the execute nodes. the output of 'qconf -sconf' contains: login_shells sh,bash,ksh,csh,tcsh qlogin_command builtin qlogin_daemon builtin rlogin_command builtin rlogin_daemon builtin rsh_command builtin rsh_daemon builtin (as far as i read this was the problem of a thread some time ago in this list. But i seem to have the correct values) So everything should be fine- or not? Also with qlogin -l 'h=exec01' and qrsh -l 'h=exec01' i can go without problems to the first node.(called exec01), and i can also login to all other execute nodes as well. Is there anywhere another 'switch' where i can let qsub run _not_ over ssh? If is is of interest, the output of 'qconf -sp orte' is: pe_name orte slots 9999999 user_lists NONE xuser_lists NONE start_proc_args NONE stop_proc_args NONE allocation_rule $round_robin control_slaves FALSE job_is_first_task TRUE urgency_slots min accounting_summary FALSE qsort_args NONE Also, i do not have any ssh lines in ~/.profile or ~/.bashrc Kind regards, ulrich _______________________________________________ users mailing list users@gridengine.org https://gridengine.org/mailman/listinfo/users
