# [Research IT Documentation](#research-it-documentation)

Research IT (previously The Trinity Centre for High Performance Computing, TCHPC) provides High Performance Computing (HPC) and other computationally intensive resources to Trinity College Dublin researchers.

[HPC Clusters](https://www.tchpc.tcd.ie/hpc-clusters) Research IT maintain.

## [Get access to HPC resources](#get-access-to-hpc-resources)

To access any of the HPC Clusters we maintain you will require:

1. A Research IT **account**. This account is separate from your Trinity College network login account you use to access email, etc.
2. A **resource allocation** on each HPC Cluster. Access is not automatically granted to any of the HPC Clusters we maintain.

### 1. Accounts

To request a Research IT account please email [rit-support@tcd.ie](mailto:rit-support@tcd.ie) and include the following information:

1. Your **full name** and **email address**. We will use your Trinity College network login username.
2. The name and email address of the **Principal Investigator you are working with** in Trinity.
3. Your **status in College**, e.g. are you an Undergraduate or Postgraduate Student, or a member of Staff, etc.
   - If you are an Undergraduate Student we will require confirmation from your academic supervisor.
4. If you are **not a Trinity student or staff member** you must fill out and return a [third party access form](https://www.tchpc.tcd.ie/docs/assets/Third_Party_Access_Form.pdf) to us before your account request can be considered. If you are not a Trinity student or staff member please also include your requested username.

### 2. Resource Allocations

[Callan](https://www.tchpc.tcd.ie/docs/callan/) is the HPC Cluster that is generally **available to all Trinity researchers**. Most of the other HPC Clusters we maintain are only accessible to members of certain research groups who purchased the cluster.

To request a resource allocation on one of the [HPC Clusters](https://www.tchpc.tcd.ie/hpc-clusters) we maintain, including Callan, please email us on [rit-support@tcd.ie](mailto:rit-support@tcd.ie) with the following information:

1. Your Research IT **username**.
2. The **name of the HPC Cluster** you are requesting access to.
3. The name and email address of the **Principal Investigator** you are working with in Trinity.
4. A statement on the **nature of the data** you will need to store on the HPC Cluster. Please clarify if the data is subject to the GDPR. Or subject to any other sensitivity classification such as sensitive or identifiable as per these [data classifications](https://www.tcd.ie/itservices/keeping-it-secure/data-classification/).

Please note that sensitive data coming under the GDPR cannot be stored or analysed on the Callan HPC Cluster.

## [Passwords](#passwords)

Research IT Account [password change service](https://password.tchpc.tcd.ie/). **You must know your password** to be able to change it from that site.

To request a password reset please email [rit-support@tcd.ie](mailto:rit-support@tcd.ie).

## [SSH Keys](#ssh-keys)

**Both** your Research IT *password* **and** an *SSH key* pair are required to log into `rsync.tchpc.tcd.ie` **from the internet**. From the **College network** you will only need 1 of your *password* **or** *SSH key* pair.

### [Instructions](#instructions)

- [Using an SSH key pair on Windows to login](https://www.tchpc.tcd.ie/docs/cluster-usage/#ssh-key-pairs-windows-clients)
- [Using an SSH key pair on Linux to login](https://www.tchpc.tcd.ie/docs/cluster-usage/#ssh-key-pairs-linux-macos-os-x-clients)

### [Locked out](#locked-out)

You can add a ssh key to your `rsync` account as per the relevant instructions above from a computer connected to the College network, including VPN. If you are connected to the College network you do not need Research IT to add an ssh key for you.

If you cannot access the College network but need to add a ssh key to your `rsync` account please send your **public ssh key** to [rit-support@tcd.ie](mailto:rit-support@tcd.ie), (**do not send your private key**),
from the `@tcd.ie` email address registered with your Research IT account, and we will add it for you.

Users who don't have an `@tcd.ie` email address and need us to add an SSH key should email [rit-support@tcd.ie](mailto:rit-support@tcd.ie), we will have to liaise with your collaborator in Trinity to confirm your identity.
