Simple example for running on multiple nodes on Ostrava Cluster?

[maarzt]

There should be an example on how to run a command on the Ostrava cluster on multiple nodes. It should be very simple, maybe something like this (Consider the code example as a draft):

@Parameter ParallelService parallelService;
@Parameter UIService ui;

List<Map<String, Object>> paramters = initParameters();
ParallizationParadigm paradigm = parallelService.getParadigm(OstravaParadigm.class, "username", "password", 8);
paradigm.runAll(RotateImageXY.class, parameters);
for(Map<String, Object> map : parameters)
    ui.show(map.get("image"));
