This framework allows users to run time-critical work at ECMWF. Some general background information can be found in a document from the ECMWF Technical Advisory Committee.
This service is available in three options:
Option 1: A mechanism to submit "Simple time-critical jobs" linked to the ECMWF operational activity.
Options 2 & 3: To run more complex time-critical work at ECMWF. These options are described in more detail in Options 2 and 3.
Users can also use the infrastructure used for the option 1 above (events, notifications, subscriptions) to manage their own activities. This can be done with the "ecevent" command.
