The Holland Computing Center (HCC) provides high-performance computing resources for Universities and Colleges in the state of Nebraska. HCC supports both research and creative, and class activity.
This guide provides a list of useful links for classes utilizing HCC resources.
## Useful Links for Instructors
- Class group creation [form](https://hcc.unl.edu/new-group-request).
- Class group renewal [form](https://hcc.unl.edu/class-renewal-request).
- Link to HCC class [policy page](https://hcc.unl.edu/hcc-policies#class-groups)
- Some class may utilize custom conda environments. Some conda environments, especially the GPU-based ones, can be very large and can easily exceed the available $HOME quotas of 20GBs. To avoid this, we recommend creating group-level custom conda environment. If you are interested in this, please email hcc-support@unl.edu for further information.
- If data needs to be shared among all group members, please see https://hcc.unl.edu/docs/handling_data/swan_data_sharing/#using-group-level-shared-directory for best practices.
- You can request HCC training/presentation [in-class](https://hcc.unl.edu/docs/faq/#can-hcc-provide-training-for-my-group).
### Tips
- Add some assignment at the beginning of the class so students can create class accounts and setup Duo before the beginning of the class
## Share Data

## Support
- When to email HCC and when to email the class TA
- For issues related to classwork or assignment please contact your TA. For issues with HCC resources (e.g., unavailable resources, sudden errors and job failures), contact [HCC support](mailto:hcc-support@unl.edu.)

- Creating and setting HCC accounts takes some time. To motivate students to create HCC accounts before the training/assignments are due, some professors make this process a graded assignment.

### Account creation and setup

- If you already have existing HCC account, use the Supplementary Group request [form](https://hcc.unl.edu/group-addchange-request) instead.

### Application links
- HCC Open OnDemand (OOD) [web access to Swan](https://swan-ood.unl.edu/).
- Detailed HCC Open OnDemand [guide](https://hcc.unl.edu/docs/open_ondemand/).
- If the OOD resources are not enough, you can run JupyterLab Notebooks within [SLURM job](https://hcc.unl.edu/docs/applications/submitting_jupyter_code/running_jupyter_lab_code).
- Custom conda environments are created in $HOME by default. You can change the location of the [conda environment](https://hcc.unl.edu/docs/applications/user_software/using_anaconda_package_manager/#using-common-for-environments/).
- Custom conda environments can easily fill the 20GBs quota on $HOME. To clean space, you can [remove unused Anaconda packages and caches](https://hcc.unl.edu/docs/applications/user_software/using_anaconda_package_manager/#remove-unused-anaconda-packages-and-caches).
