Using Ansys with Open On Demand

Overview

How to use the CXFEL Ansys installation with Open on demand, on Agave.

In order to use Ansys, you will need to supply your ASURITE to Research Computing, so they may add this to the license file.

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

Open

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

Open

You will then click “Agave Virtual Desktop” which will give you the following

Open

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.

Open

Once this has started, you will hit the “connect” button to open the instance and begin working.

Running Ansys

Once you open you virtual desktop, you will arrive at a screen like this.

From here you will want to open the “terminal” and run the following command
