There are two ways to get .so files on the nodes that I know of.  The
first is to use bplib to add the files to the nodes.  This is useful
when you have a program that needs a new .so, but needs to be done
everytime the nodes are rebooted.

A more perminant solution is to use the libraires plugin in
/etc/beowulf/config.  ex:

# GM
libraries /usr/lib/libgm.so*
 
# PGI
libraries /opt/pgi/linux86/lib/


New libraries listed in beowulf/config are not picked up by the
nodes until bpmaster (I think) is restarted on the host, which is why
a combination of bplib to get the lib out the first time and adding it
to beowulf/config is how I usually push out a new library.
