Getting Started (Tutorial) #

Step 1. Requesting Access to Orca #

The first step is to request access to Orca. See the page on Requesting Access. After your account has been created and activated, continue on to Step 2.

Step 2. Set up SSH Authentication #

After account creation, you need to set up an SSH key pair to use with Orca. If you have an SSH key pair already, upload the public key to the Orca Registry. If not, then generate a new key pair by running ssh-keygen in the terminal, and then upload the newly generated public key. See the documentation on connecting via SSH for more information.

Step 3. Connecting to Orca #

After your Orca account has been provisioned and SSH authentication has been set up, you can connect to Orca via ssh by running

ssh username@login.orca.pdx.edu

where username is replaced with your Orca username. See the documentation on Connecting to Orca for more information.

Step 4. Requesting an Interactive Session #

Once you have logged into Orca, you can request an interactive session on a compute node. For example, the following will request an interactive session for 10 minutes with one CPU core

salloc -n 1 -t 10

Note that this will only give you access to a single core and no GPUs. For more information about requesting more resources (including GPUs) and submitting batch jobs, see the documentation on Submitting Jobs.
