High Performance Linux Clusters with OSCAR, Rocks, OpenMosix, and MPI [Electronic resources] نسخه متنی

10.3 Notes for OSCAR and Rocks Users

C3 is a
core OSCAR package that is installed in
/opt/c3-4 and can be used as shown in this
chapter. Both Ganglia and Clumon (which uses Performance Co-Pilot)
may be available as additional packages for
OSCAR. As add-ons, these may not always be
available immediately when new versions of OSCAR are released. For
example, there was a delay with both when OSCAR 3.0 was released.
When installing Ganglia using the package add option with OSCAR, you
may want to tweak the configuration files, etc.

Although not as versatile as the C3
command set,
Rocks supplies the command
cluster-fork for executing commands across a
cluster.

For OSCAR, the web-accessible reports for Clumon and Ganglia are
installed in /var/www/html/clumon and
/var/www/html/ganglia, respectively. Thus, to
access the Ganglia web report on
amy.wofford.int, the URL is http://amy.wofford.int/ganglia/. The page
format used by OSCAR is a little different, but you would use Ganglia
in much the same way.

Ganglia is fully integrated into Rocks and
is available as a link from the administrative home for the
frontend.
