11.2 Notes for OSCAR and Rocks Users


As
previously noted, both OpenPBS and Maui are installed as part of the
OSCAR setup. The installation directory for OpenPBS is
/opt/pbs. You'll find the
various commands in subdirectories under this directory. The working
directory for OpenPBS is /var/spool/pbs, where
you'll find the configuration and log files. The
default queue, as you may have noticed from previous examples, is
workq. Under OSCAR, Maui is installed in the
directory /opt/maui. By default, the OpenPBS
FIFO scheduler is disabled.

OpenPBS and Maui are available for Rocks as a separate roll. If you
need OpenPBS, be sure you include the roll when you build your
cluster as it is not currently possible to add the roll once the
cluster has been installed. Once installed, the system is ready to
use. The default queue is default.

Rocks also provides a web-based interface for viewing the job queue
that is available from the frontend's home page.
Using the web interface, you can view both the job queue and the
physical job assignments. PBS configuration files are located in
/opt/torque. Manpages are in
/opt/torque/man. Maui is installed under
/opt/maui.
