Log in to Snowy

Here we describe how to log in to Snowy

Prerequisites

• User account: visit the UPPMAX page on user accounts
• A local UPPMAX project: see project. Snowy is available as compute nodes only

Reach the Snowy compute nodes

To make Snowy do a calculation, one needs to log in to a Rackham login node, which is described here.

After logging in, one can

• Start a batch job using Snowy resources
• Start an interactive job

    graph TB

    Node1 -- interactive --> SubGraph2Flow
    Node1 -- sbatch --> SubGraph2Flow
    subgraph "Snowy"
    SubGraph2Flow(calculation nodes)
    end


    subgraph "Rackham"
    Node1[Login] -- interactive --> Node2[calculation nodes]
    Node1 -- sbatch --> Node2
    end
