Cluster users need passwordless ssh so that batch scripts can execution
programs on other nodes (multi-node jobs only), and so that output files can be
delivered back to the submit hosts.

From the usage my Torque should hasve "--with-scp" enabled. But my log files in /var/spool/torque/*_log do not contain words such as scp.

If you didn't specify, then the default of scp is used.  Scp is used when
copying output files back to submit hosts.
