[Beowulf] Software installation across cluster

[Douglas Eadline]

There are a couple of ways. If you are talking system
files and OS images, check out Warewulf, http://warewulf.lbl.gov/trac

I have found placing packages in /opt/ and sharing via NFS
works well for small to medium systems. I make a directory
called /opt/etc/ld.so.conf.d/ and place the package library
conf files in this directory.

I then add "include /opt/etc/ld.so.conf.d/*.conf" to the node
/etc/ld.so.conf file. That way, I don't need to reboot or change
anything on the nodes when I add a new package. It is installed in
NFS and then I issue a "pdsh ldconfig"

Actually I package everything in rpms, so all this gets done
automatically when things are installed. I use Modules and install a
Modules file for each package that sets paths etc., it can
override the ld.so.conf files if needed by using a LD_LIBRARY_PATH.
I also do some sshd_conf twiddling so user Module state is preserved
across logins to cluster nodes.
