Hi Patrick,

please excuse me not responding to your e-mail yet. All in all your approach is viable and one we had already pursued as part of CACTOS. I will write up a response with a couple of pointers later tonight.

Best regards
Christian

Subject: [I43-doktoranden] [palladio-dev] Simulate load balancing strategies using SimuLizar

Hi,

I want to simulate different load balancing strategies using SimuLizar.
This strategies depend on the  runtime state of the model, such as the already running jobs on a resource container.
However, I'm not entirely sure how this could be implemented, because I'm not that familiar with SimuLizar's internals yet.

My approach would be to use the reconfiguration feature of Simulizar.
The reconfiguration transformations
are triggered by measuring points, right? So I would have to create measuring points for component start/end, can this be done?

When the transformation is triggered it has to retrieve all running components, find the best fitting resource container, and start the component on this resource container. Is this possible?
If there is no suitable resource container available, I want to put the component into a queue, and submit it to a resource container later.

Do you think that this is realisable or is it the wrong approach?

Thank you for your help,
Patrick
