IFD runs

localRun

Workflows By default all the workflows started from a leaf node are by default started in IFD mode (i.e. local run). The results of an IFD-run are only temporary available in FEWS (until the next restart) and are only available and visible at the operator client which started the run. IFD runs are typically used to evaluate the effect of modifiers on the results of a forecast.

Server run

A workflow which is Workflows started from a group node will (nodes) are by default be started as a server run. A server run will run at a FSS when it is started from an operator client. When it is started from a stand alone it will run locally but the results of the run will be available after a restart of the system.

It is possible to You can change these default settings by using with the element localRun<localRun>.In  In the example below the runs from leaf nodes A (localRun=false) and B (defaults to false) will run in server mode and the runs started from the group node C will run in IFD mode (localRun=true).

previousNodeId

It is possible to connect nodes in the topology. In the example below the node STKA2 is connected to two previous nodes (SBFQ2 and ISKQ2). The way nodes are connected plays an important role when running workflows in IFD mode. 

<node id="STKA2" name="STKA2 Stikine R Wrangell">
		<previousNodeId>SBFQ2</previousNodeId>
		<previousNodeId>ISKQ2</previousNodeId>
		<workflowId>STKA2_Forecast</workflowId>
</node>

Example previousNodeId

The example below shows the situation before the forecaster starts an IFD run for the node STKA2. The topology tree shows that this node has not run yet (icon is a black dot)  and that it is connected to two previous nodes SBFQ2 and ISKQ2.

Image ModifiedImage Added

When the forecaster starts an IFD run for node STKA2 (see arrow) Delft-FEWS will detect that node STKA2 is connected to two other nodes which have to run before the run for STKA2 can be started.One  One of these nodes (SBFQ2) also has a previous node which has to run prior to running this node. Before running node STKA2 the IFD system will make sure that first all the necessary previous nodes are run in the correct order before node STKA2 will be run. The example below
The screenshot on the right shows the forecast tree after the run for STKA2 was finished. It shows that not only an IFD run was started for STKA2 but also for all its previous nodes.Image Removed

enableAutoRun

By default the workflow on a leaf node is started automatically after selecting the node. This can be disabled by setting the option <enableAutoRun> to false.The  The option will apply to all nodes.

enableRunUpstreamServerNodes

For IFD (local) runs the connected previous nodes are always started before the IFD run for the selected node can be run. 

For server runs the connected previous nodes are by default not taken into account. If the option <enableRunUpstreamServerNodes> is set to true the previous nodes will also be started prior to running the workflow of the selected node.

checkStatusPreviousServerRun

The option <checkStatusPreviousServerRun> can be used to force that a server run can only be started if the status of all of its previous nodes is fully successful. 

enableCrossGroupNodeReferencing

Previous nodes which are connected to a node but belong to a different group in the topology tree are ignored by default when starting previous nodes for a selected node. By setting the option <enableCrossGroupNodeReferencing> to true previous nodes in a different group will also be taken into account.

Please noteNote,  if if the same workflow node is selected more than once, and a description is specified, then a notification dialog pops up after the OK button is clicked. If the user chooses to change the description, then the edit run options dialog comes back, and the description text would be selected (which indicates the description text is ready to be edited).

Secondary workflow

It is possible to define a secondary workflow for a node. This secondary workflow can be run by clicking the button  in the button bar.
