Executing the examples

You need to have a running DIET platform with a MA agent and the needed services registered - You can for example launch a single SeD that includes all the needed services (e.g., scalar_server if the workflow only performs operations on scalar). You can find details on how to develop a SeD in Chapter 5.

The directory src/examples/workflow includes several code examples of workflows. For example,

• you can find a simple DAG workflow (see Figure 15.1) in the file xml/scalar.xml. You can test it with a command such as the following, where local_client.cfg is the DIET configuration file (etc/client_wf.cfg is provided as an example);

  ./generic_client local_client.cfg -dag scalar.xml

• you can also find some examples of functional workflows written in the Gwendia language (see file xml/func_string.xml). You can perform some tests with commands such as:

  ./generic_client local_client.cfg -wf func_string.xml data.xml
