+# User Requests
+
+Sometimes, users may request access to additional software packages, more disk quota, or longer SLURM job time limits.
+This document outlines the process of handling such requests.
+
+Prior to performing changes for the request, WATcloud admins should understand the request fully and consider the implications of the change.
+The following questions are examples of what the admins should consider:
+
+**Does the request make use of cluster resources in a fair and efficient manner?**
+
+For example, if a user requests more disk quota, the WATcloud admin should consider whether the type of data
+the user is storing is appropriate for the storage location.
+For instance, long-term storage of large datasets on SSD-backed storage may not be the most efficient use of resources.
+
+**Can the request be fulfilled without the help of WATcloud admins?**
+
+Sometimes, the requested work can be done by the users themselves.
+The WATcloud admin should point the user to the relevant documentation or resources, and improve the documentation if necessary.
+For example, if a user requests a software package that can be installed in user-space (e.g. Conda),
+the WATcloud admin should point the user to some options (e.g. [miniconda](https://docs.anaconda.com/miniconda/)).
+
+In subsequent sections, we will discuss specific user requests and how to handle them.
+
+## SLURM Job Time Limit Extension
+
+Users may request an extension to the time limit of their SLURM[^slurm-docs] jobs.
+The time limits are in place to ensure that the cluster remains maintainable.
+For example, if the maximum time limit jobs is 7 days, then in the worst case scenario,
+we need to wait 7 days for a node to be drained before performing maintenance[^slurm-maintenance] on it.
+
+If a user requests an extension to the time limit and the request does not conflict with upcoming maintenance,
+then the WATcloud admin can extend the time limit as follows:
+
+```bash copy
+scontrol update job=<job_id> TimeLimit=<new_time_limit>
+```
+
+[^slurm-docs]: See the [SLURM documentation](/docs/compute-cluster/slurm) for more information on the use of SLURM in the WATcloud cluster.
+[^slurm-maintenance]: See the [Maintenance Manual](./maintenance-manual#slurm) for information on performing maintenance on SLURM nodes.
+
+## Software Package Installation
+
+Users may request the installation of software packages that are not already available on the cluster.
+If the software package is required to be installed system-wide and the demand for the software outweighs
+the cost (in terms of storage space and maintenance complexity) of installing the software,
+then the WATcloud admin can add the software package to the cluster Ansible configuration[^ansible-config].
+
+[^ansible-config]: At the time of writing, the Ansible configuration can be found [here](https://github.com/WATonomous/infra-config/blob/7d59786e61ce779f20e7cdb8c29b4864fe1b6c31/ansible/roles/ubuntu_dev_vm/tasks/main.yml#L94-L144).
+    Note that removing software packages is a separate step [here](https://github.com/WATonomous/infra-config/blob/7d59786e61ce779f20e7cdb8c29b4864fe1b6c31/ansible/roles/ubuntu_dev_vm/tasks/main.yml#L27-L65).
