## Cluster specification

### Compute nodes

Santis consists of around ??? [Grace-Hopper nodes][ref-alps-gh200-node].
Santis consists of around 600 [Grace-Hopper nodes][ref-alps-gh200-node].

!!! note
In late March 2025 Santis was temporarily expanded to 1233 nodes for [Gordon Bell and HPL runs][ref-gb2025].

The number of nodes can change when nodes are added or removed from other clusters on Alps.

There are four login nodes, labelled `santis-ln00[1-4]`.
You will be assigned to one of the four login nodes when you ssh onto the system, from where you can edit files, compile applications and start simulation jobs.

### Getting access

Project administrators (PIs and deputy PIs) of projects on the MLp can to invite users to join their project, before they can use the project's resources on Alps.
Project administrators (PIs and deputy PIs) of projects on the MLP can to invite users to join their project, before they can use the project's resources on Alps.
This is performed using the [project management tool][ref-account-waldur]

Once invited to a project, you will receive an email, which you can need to create an account and configure [multi-factor authentication][ref-mfa] (MFA).

## Systems
