I have installed openpbs-20.0.0 on one server and two execution nodes. (total 3 nodes)
I also checked that nodes are communicated well when creating vnodes via qmgr.
My question is
- Should I enable passwordless ssh?
I want to avoid that a new user access to the execution node.
As I use NFS, I add two lines in ‘var/spool/pbs/mom_priv/config’:
$usecp *:/home /home
$usecp *:/data /data
(I found this in http://docs.adaptivecomputing.com/torque/3-0-5/6.2filesystems.php)
- With the setting I have done, openmpi does not work when I submit two-node jobs.
The output log shows that
‘ORTE was unable to reliably start one or more daemons. …’
I have checked that one-node job works well.
Is this due to the ssh authentication?
I set the zone to trusted with eno2 (internal network).
