An array of ParallelServer(s).
ParallelServerArray is an ParallelSystemArray specialized in servers' driver.
DistributedSystemArray class is an ExternalSystemArray and an abstract class containing and managing distributed system drivers within framework of master. The DistributedSystemArray class allocates DistributedSystemRole objects to DistributedSystem objects for optimization.
Unlike the ExternalSystemRole class which is dependent on an ExternalSystem, DistributedSystemRole is not dependent on a DistributedSystem and even can be allocated to multiple DistributedSystem objects. Allocation of DistributedSystemRole(s) to DistributedSystem(s) is determined by estimation of performance index pursuing best distribution. If number of DistributedSystem and DistributedSystemRole objects is not a lot, optimize by combined permuation algorithm. Else the objects are a lot, the allocation will be optimized by genetic algorithm.
ExternalSystemArray is an abstract class containing and managing external system drivers.
Also, ExternalSystemArray can access to ExternalSystemRole(s) directly. With the method, you can use an ExternalSystemRole as "logical proxy" of an ExternalSystem. Of course, the ExternalSystemRole is belonged to an ExternalSystem. However, if you access an ExternalSystemRole from an ExternalSystemArray directly, not passing by a belonged ExternalSystem, and send an Invoke message even you're not knowing which ExternalSystem is related in, the ExternalSystemRole acted a role of proxy.
It's called as "Proxy pattern". With the pattern, you can only concentrate on ExternalSystemRole itself, what to do with Invoke message, irrespective of the ExternalSystemRole is belonged to which ExternalSystem.
