# Directory Structure¶

We organize the unstructured data corresponding to simulation files under a certain hierarchic directory structure, as explained in the present page. The storage quotas which pertain to the folders presented herein are explained in the corresponding documentation page.

## Permissions¶

We organize our directories under a Linux/Unix filesystem 1, where standard permissions apply 2. We refer the Reader to the original sources of explanation about the Unix permissions.

We associate Users with operating system users, and Accounts with operating system groups. This way the data generated within an account is not accessible to anyone else, but the members of this account, unless explicitly shared. Shared access for the members of the same organizational account is explained further here.

When first accessing the platform via any of the remote connection methods, users initially enter the login node. The directory where user lands upon login is referred to as the Login Home. This directory is at the head of a hierarchical directory structure further described in this dedicated section .

## Cluster Homes¶

Each computing cluster has its own distinct home folder, referred to as the Cluster Home, which is "mapped" under the aforementioned Login Home. The contents of cluster homes are further documented in this page.

## Dropbox¶

As explained in this dedicated section, Dropbox is a universally available storage, allowing data and files to be shared across the platform. The absolute path to the Dropbox folder is /dropbox/<username>/. A link to it is present under both the Login and Cluster home directories.

## Job Script Templates¶

A shortcut to a folder containing some quick examples (templates) for command line jobs is also present under both the login and cluster home directories. It contains specific examples of batch scripts for running Jobs via the Command Line Interface. This folder is stored under the absolute path /export/compute/job_script_templates.
