[palladio-dev] [sdq-dev] SimuCom/PCM: Multiple resources of the same ActiveResourceType in the same resource container

Hi Christian,

I think this is just implementation specific. Nonetheless, there are some problems due to the fact that ResourceDemands are usually only specified resource type wise, so adding another resource of the same type might implicate some kind of (advanced) resource dispatching.
If you just want to model a dual core processor or alike, I remember there was some kind of replication attribute?!

best regards
Joerg

This causes issues when it is expanded multiple times in the same ResourceContainer for the same ActiveResourceType.
