On Demeter and Loren when you compile new packages for all users or reboot a node you will have to copy the module files to the node/s.
1) ssh into the node
2) copy the file using:
cp -ru /share/apps/modulefiles/compilers/ /usr/share/Modules/modulefiles/
1) in root type:
rocks iterate host compute "scp -r /share/apps/modulefiles/compilers/ %:/usr/share/Modules/modulefiles/"
1) ssh into the node
2) copy the folder using
cp -ru /share/apps/modulefiles/apps /usr/share/Modules/modulefiles/
1) in root type:
rocks iterate host compute "scp -r /share/apps/modulefiles/apps %:/usr/share/Modules/modulefiles/"
