File Structure

The file structure on a Talapas login node or compute node follows the typical directory structure found on a standard Linux server. As a user, there are several locations to store your data:

Home directory

/home/<username> - your home directory has a 250GB quota and is only accessible by you. Store your personal work related data here.

Projects directory

/projects/<pirg> - your PIRG project directory has its own quota, the standard is 2TB. Store lab work related data here and data used in collaborations with other members of the lab.

A symbolic link is created by default in each users home directory to provide a direct link to each PIRG that you are a member of. For example, members of racs each have the following link in their home directories,

The project directory is owned by the lab PI and all members of the PIRG have read/write access to files and directories created here to enable collaboration.

Navigate to the PIRG projects directory through the symbolic link racs:

Or through the explicit directory direct path:

Projects - Legacy

This directory is where I can store my PIRG related files. For each PIRG you’re a part of, you have a /home/<pirg> symlink in your home directory which goes to /projects/<pirg>/<username>. The PIRG directory /projects/<pirg> is owned by the PI. Your user directory /projects/<pirg>/<username> is owned by you. Members of the PIRG have read/write access to the PIRG shared /projects/<pirg>/shareddirectory. Files and directories created in shared inherit the PIRG group ownership to help with collaboration. You must explicitly grant write access for every file you wish other members of your PIRG to have write access. By default, the project has a 2TB quota and can be increased by purchasing additional storage.

For example, here is my home directory. Notice the symlink from racs to /projects/racs/marka.
