Write your scripts
ecf script will correspond with the task in the suite definition. The script defines the main work that is to be carried out. The script includes child command s and special comments and manual sections that provides information for operators.
The child command s are a restricted set of ecflow_client commands that communicate with the ecflow_server. They inform the server when the job has started, completed or set some event.
Start a server
After ecflow_server is started, the suite definition, can then be loaded into it.
- The user then initiates scheduling in the ecflow_server
- scheduling will check dependencies in the suite definition every minute. If these dependencies are free, the server will submit the task. This process is called job creation. The running process corresponding to the task is referred to as a job.
The running jobs will communicate back to the server using child command s. These cause:
Use the GUI
ecFlow has a specialised GUI client, called ecflowview. This is used to visualise and monitor:
- The hierarchical structure of the suite definition. (suite, family, task)
- state changes in the nodes and server.
- Attributes of the nodes and any dependencies.
- ecf script file and the expanded job file.
In addition ecflowview provides a rich set of ecflow_client commands that can interact with the server.
