Basics of usage
mUQSA is a web portal that can be used from any modern web browser. Let’s briefly demonstrate how to create and run an example UQ&SA scenario with the portal.
Note
Procedure of defining and running tasks with mUQSA is described in more detail in Tutorials.
Once registered and logged-in, a user is provided with the main view of the portal, which is the list of submitted tasks. At the beginning it is empty, but it will be filled-up with the UQ&SA tasks once they are defined.
To create a new scenario, you need to click on a Submit a job button. Then you will need to find the mUQSA template and click Submit a job on it.
You will be provided with the welcome-page of the mUQSA wizard that will guide you step by step through different stages of UQ&SA task preparation. In this first screen, you may decide if you want to define a new scenario from scratch or to load a previously prepared configuration.
Once decided, you will be asked to give a name for the task, and then forwarded to the actual 6-step wizard.
The progress indicator at the top of the view displays the information about the current stage as well as it allows you to move between stages. Once all necessary data is defined, you can push the Submit button to schedule a task for the execution on an HPC cluster. At any step, you can also Save your configuration for the later usage.
When creating a new configuration, the first steps will be to define the parameters of the model whose uncertainty needs to be studied, and to select the appropriate method for the required analysis. Then you will move on to configure some more technical aspects, including Encoder and Decoder, model selection and finally how the analysis should be run. Once all the necessary information is set up, the analysis can be submitted for the execution on an HPC resource.
Upon completion of a task, when you select the Results tab in task’s details window, you will be presented with a screen displaying the analysis results. This screen includes a collection of statistics and plots. For a detailed guide on interpreting these results, please refer to the Analysis section.
