The OpenQuake Engine Server provides an HTTP RESTful API and a web GUI, the WebUI. It's built on top of Django, jQuery and BACKBONE.js.
The OpenQuake Engine Server is used to submit new jobs, watch calculation progress, retrieve results and more.
The API document provides the full list of available endpoints. Several authentication mechanisms are supported and can be enabled with a custom configuration.
The OpenQuake Engine WebUI does not require any special software on the client side except for a browser. Supported browsers are:
- Mozilla Firefox >= 38
- Google Chrome
- Microsoft Internet Explorer >= 10
- Microsoft Edge
- Apple Safari >= 6
Double click on the "OpenQuake Engine (webui)" icon located on the desktop, or use the link in the 'Start' menu.
In a terminal type:
$ oq webui startA systemd service will take care of the OpenQuake Engine server, starting it at boot.
Please refer to Configure the systemd services page.
Open the browser and load the http://localhost:8800/engine page
Before starting a new calculation you need to prepare inputs. All the inputs file and the job.ini must be placed in a compressed zip file.
To start a calculation, having the input zip file, select the Run a Calculation button in the header menu. A dialog window will appear: select the zip file to be uploaded and press Open to confirm
Each running calculation can be stopped with the Abort button; this will interrupt the calculation immediately and revoke any pending task for that specific job.
Note: only a calculation started from the WebUI can be stopped via the Abort button; to stop a calculation started by the command line interface the oq abort command must be used instead.
It is possible to watch the log from a running calculation
The log from a previous run can be also inspected.
If a calculation has run successfully an Outputs button is provided. Click the Outputs button to see the list of outputs available for the specific calculation type.
Output availability depends on the type of artifacts generated by the calculation. The possible formats are xml, csv, npz, zip. Click on the desired output/format to download the corresponding file
To run a postprocessing or risk calculation on top of a previous hazard one you have to click the Continue button on the corresponding hazard calculation and select the zip file containing the job.ini and the related inputs
To hide a calculation from the list press the Remove button
The calculation is removed from the calculations list, but it is not actually removed from the database nor from the datastore.
A calculation can be in one of the following statuses: created, executing, complete, failed
The reason behind a failed calculation can be inspected by using the Traceback button.
Please refer to the OpenQuake IRMT QGIS plugin documentation.
