The OpenQuake Engine can be run via a command line interface or a WebUI. For the WebUI have a look to its documentation.
The OpenQuake Engine command line tool is oq. To run a calculation the command oq engine must be run.
There are several demo calculations included with the package. Depending on the installation they are located in /usr/share/openquake/engine/demos. or ~/openquake/share/engine/demos/or just oq-engine/demos in the source repository.
An example of running the AreaSourceClassicalPSHA demo:
[user@centos7 ~]$ oq engine --run /usr/share/openquake/engine/demos/hazard/AreaSourceClassicalPSHA/job.iniThe output should look something like this:

To interrupt a running calculation simply press CTRL-C.
For a list of additional commands, type oq engine --help.
When the OpenQuake Engine is driven via the oq command over an SSH connection an associated terminal must exist throughout the oq calculation lifecycle.
To avoid the openquake.engine.engine.MasterKilled: The openquake master lost its controlling terminal error you must make sure that a terminal is always associated with the oq process.
For non-interactive jobs run in batch we suggest the use of nohup which is part of every Unix like OS:
[user@centos7 ~]$ nohup oq engine --run /usr/share/openquake/engine/demos/hazard/AreaSourceClassicalPSHA/job.ini &> /tmp/calc.log &More info about nohup: https://en.wikipedia.org/wiki/Nohup.
For an interactive use of oq we suggest to install byobu on the target server and use it to run oq.
More info about byobu: http://byobu.co/.
