If you have code you'd like to share among the compute nodes, but your code isn't in an RPM (or in a roll), then this procedure describes how you can share it with NFS.
On the frontend, go to the directory /share/apps.
# cd /share/apps
Then add the files you'd like to share within this directory.
All files will also be available on the compute nodes under: /share/apps. For example:
# cd /share/apps # touch myapp # ssh compute-0-0 # cd /share/apps # ls myapp
