# Login to our cluster

### Slrum

To log in to the frontend, the ssh client program can be used, and the user types Command Line Interface (CLI) commands to tell the computer what to do. The ssh client program is available on Linux, MacOS (with Terminal) and MS Windows 10 machines (with PowerShell). For older Microsoft Windows machines, the [PuTTY![](https://twiki.cern.ch/twiki/pub/TWiki/TWikiDocGraphics/external-link.gif)](https://www.putty.org/) ssh client is recommended.

```
ssh your_user_name@escience0.sc.chula.ac.th
```

Note that **`escience0`** is the load-balancing IP address. It should be fine to use for any job submissions. However, if you would like to compile your code with specific hardware, i.e. GPU, you should log in to a specific machine. We don't recommend using the login machines to run your code if not necessary, jobs will be killed if it consumes a lot of resources of the frontend nodes. 

* `escience1.sc.chula.ac.th`: small frontend machine, for job submission, monitoring only. 
* `escience2.sc.chula.ac.th`: small frontend machine, for job submission, monitoring only. 
* `escience3.sc.chula.ac.th`: frontend with Tesla G4 CPU.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://esciencecu-twiki.sc.chula.ac.th/introduction-to-our-cluster/login-to-our-cluster.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
