Detailed Description

template<class System = ParallelSystem>
class samchon::templates::parallel::ParallelClientArrayMediator< System >

Mediator of Parallel Processing System, a server accepting slave clients.

The ParallelClientArrayMediator is an abstract class, derived from the ParallelSystemArrayMediator class, opening a server accepting parallel clients as a master.

Extends this ParallelClientArrayMediator and overrides below methods creating child ParallelSystem object. After the overridings, open server with open() method and connect to parallel servers through the connect() method. If you want this server to follow web-socket protocol, then overrides WebServer virtually.

[Inherited] ParallelSystemArrayMediator}

Mediator of Parallel Processing System.

The ParallelSystemArrayMediator class be a master for its slave systems, and be a slave to its master system at the same time. This ParallelSystemArrayMediator be a master **system, containing and managing ParallelSystem objects, which represent parallel slave systems, by extending ParallelSystemArray class. Also, be a **slave system through mediator object, which is derived from the SlavSystem class.

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

ParallelClientArrayMediator: A server accepting parallel clients.

ParallelServerArrayMediator: A client connecting to parallel servers.

ParallelServerClientArrayMediator: Both of them. Accepts parallel clients and connects to parallel servers at the same time.

As a slave, you can specify this ParallelSystemArrayMediator to be a client slave connecting to master server or a server slave accepting master client by overriding the createMediator method. Overrides the createMediator() method and return one of them:

A client slave connecting to master server:

MediatorClient

MediatorWebClient

A server slave accepting master client:

MediatorServer

MediatorWebServer

[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.

ParallelClientArray: A server accepting parallel clients.

ParallelServerArray: A client connecting to parallel servers.

ParallelServerClientArray: Both of them. Accepts parallel clients and connects to parallel servers at the same time.

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.

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.

ExternalSystemRole can be accessed from ExternalSystemArray directly, without inteferring from ExternalSystem, with ExternalSystemArray.getRole.

When you want to send an Invoke message to the belonged system, just call ExternalSystemRole.sendData(). Then, the message will be sent to the external system.

Those strategy is called Proxy Pattern.
