Description: dict() v.s. class

[oleweidner]

Pilot API offers classes for various 'Descriptions':

• PilotComputeDescription
• ComputeUnitDescription
• ...

However, in most of the examples and in the documentation (even in the library reference), simple Python dictionaries are used. From 5.2.1 (ComputeUnitDescription):

compute_unit_description = {
        "executable": "/bin/cat",
        "arguments": ["test.txt"],
        "number_of_processes": 1,
        "output": "stdout.txt",
        "error": "stderr.txt",
        "input_data" : [data_unit.get_url()], # this stages the content of the data unit to the working directory of the compute unit
        "affinity_datacenter_label": "eu-de-south",
        "affinity_machine_label": "mymachine-1"
    }

I assume that pilot API can do some implicit conversion. Hopever, I think the proper, more intuitive way is using the appropriate classes:

All examples and documentation should be updated to reflect this!

We updated the examples to this new and improved variable setting. Lingering is the Library/API documentation which also needs an update. Ticket should remain open until this is fixed.
