Project Map

All projects managed in the HPC Project Portal have a special directory under /projects containing symlinks to all the project’s data stores and a subdirectory for each sub-project. Specifically, the whole project tree (projects and their sub-projects) is represented as sub-directories under /projects matching the Project Structure.

In the HOME directory of every project-specific username in a project, there is the symlink ~/.project to the map directory for the project. In this directory, the symlinks to the project’s directories in each data store take the form dir.DATASTORENAME while the directories for sub-projects match the HPC Project IDs of the sub-projects. The project map directories are read-only and thus cannot be used to store data. They are provided as a convenience for accessing project data stores quickly with paths like ~/.project/dir.lustre-emmy-hdd.

For example, the project map directory for the intern/gwdg_training project is

[foo@glogin11 ~]$ ls -l /projects/intern/gwdg_training/ \
> | sed -e 's/  */ /g' | cut -d ' ' -f 1,9-

This shows the directories for the sub-projects for each course and the dir.DATASTORENAME symlinks for each of its data store directories.
