Overview
How to use the CXFEL Ansys installation with Open on demand, on Agave.
Getting started
Open on demand is a web based graphical user interface which allows for easy access to HPC resources. You can access this interface by connecting to login.rc.asu.edu. You will need to have duo 2factor enabled on your ASURITE account.
Connecting to OOD
Once you have logged in to Open on demand, you will be greeted with the following page
...
From here you will see the bar at the top, which gives you access to different parts of the HPC cluster. You will be able up upload and download files using the “Files” drop down, the command line on the hpc cluster using the “Clusters” drop down, and then In the Interactive sessions tab, you will get access to the different applications available on the system, as well as the interactive desktop.
The interactive desktop app is the one we will be using here. Once selected, you will be brought to this screen
...
You will then click “Agave Virtual Desktop” which will give you the following
...
The main pieces you will want to focus on with this form are, Session wall time and Cores.
The wall time will be how long this session will remain active, by default you can see it is set for 1 hour. You can set this up to 7 days, but the longer the job the longer it will take to get scheduled. The “cores” follow the same principle, the more cores, the longer the job will take to schedule. The default is 4 cores and you could, depending on the system, schedule up to 128 cores.
Once you have your configuration options determined, you can hit “Launch” which will start a session. You will see “Queued” until the job has started, again this could take a while depending on which options are selected, but for the defaults, it should start right away.
...
Once this has started, you will hit the “connect” button to open the instance and begin working.
