How to access GRACE and General Overview
To access the HPC simply type portal.hpc.uams.edu into your browser (Google Chrome preferred as interactive shell has issues on Safari, Firefox not tested).
You will be prompted with a login box where you will type your HPC username and temporary password.
Once you have been authenticated you will see the portal home screen:
There are several tabs at the top of the portal that are used to access various functions.
To interactively upload and browser the files in your /home/ directory go to 'Files'
To view your submitted jobs or use the job creation tool go to 'Jobs'
To get an interactive shell session within GRACE go to 'Clusters'
To run interactive apps such as Jupyter Notebook go to 'Interactive Apps'
Logging into the HPC for the first time
When you login to the portal for the first time it is essential that you use your temporary password to set a new password in order to prevent access issues.
To do this you need to use the 'Clusters' tab to open an interactive shell session within GRACE.
When you click on 'Grace Shell Access' you will be prompted to enter your password. Normally this would be the password you set, but as this is the first time you're logging in you will use the temporary password supplied to you. 
Once you have typed in your temporary password it will tell you that your password is expired and that you need to set a new password. Note password prompt asks for your current password. This would be the temporary password NOT the new password you want to set.
After you type the temporary password it will prompt you to give a new password. You will have to type it twice in order to set the password successfully. 
Once you have changed your password a success message will be displayed and you will be redirected to an interactive shell session.
Launching a Jupyter Notebook
Go to the 'Interactive Apps' tab and choose Jupyter Notebook
You will then be prompted by a window asking you what resources you want to use. These should be set on a per task basis as typically no two notebooks require the same amount of resources.
Once you have set your resources and click launch, the scheduler will reserve your requested resources. 
Notice the status of this Notebook is Queued. This means that it is not running but is waiting for resources to become available. Once the resources are available you should get an updated status like:
This is notebook session is still starting, once it has started the session will update to
Click 'Connect to Jupyter' to access your notebook.
Here you can see your files and notebooks. Click on the one you want to run and the notebook will launch.
When you are done using the notebook click 'Quit' to close the session and release the resources on the HPC.
