Detailed Description

template<class System = ParallelServer>
class samchon::templates::parallel::ParallelServerArray< System >

Master of Parallel Processing System, a client connecting to slave servers.

The ParallelServerArray is an abstract class, derived from the ParallelSystemArray class, connecting to parallel servers.

Extends this ParallelServerArray and overrides createChild() method creating child IParallelServer object. After the extending and overriding, construct children IParallelServer objects and call the connect() method.

[Inherited] ParallelSystemArray}

Master of Parallel Processing System.

The ParallelSystemArray is an abstract class containing and managing remote parallel slave system drivers, ParallelSystem objects. Within framework of network, ParallelSystemArray represents your system, a Master of Parallel Processing System that requesting parallel process to slave systems and the children ParallelSystem objects represent the remote slave systems, who is being requested the parallel processes.

You can specify this ParallelSystemArray class to be a server accepting parallel clients or a client connecting to parallel servers. Even both of them is possible. Extends one of them below and overrides abstract factory method(s) creating the child ParallelSystem object.

When you need the parallel process, then call one of them: sendSegmentData or sendPieceData. When the parallel process has completed, ParallelSystemArray estimates each ParallelSystem's performance index basis on their execution time. Those performance indices will be reflected to the next parallel process, how much pieces to allocate to each ParallelSystem.

Class Diagram

Proxy Pattern

This class ParallelSystemArray is derived from the ExternalSystemArray class. Thus, you can take advantage of the Proxy Pattern in the ParallelSystemArray class. If a process to request is not the parallel process (to be distrubted to all slaves), but the exclusive process handled in a system, then it may better to utilizing the Proxy Pattern:

The ExternalSystemArray class can use Proxy Pattern. In framework within user, which external system is connected with this system, it's not important. Only interested in user's perspective is which can be done.

By using the logical proxy, user dont't need to know which role is belonged to which system. Just access to a role directly from ExternalSystemArray.getRole. Sends and receives Invoke message via the role.
