Detailed Description

A driver for parallel slave server.

The ParallelServer is an abstract class, derived from the ParallelSystem class, connecting to remote, parallel slave server. Extends this ParallelServer class and overrides the createServerConnector() method following which protocol the slave server uses.

[Inherited] ParallelSystem}

A driver for a parallel slave system.

The ParallelSystem is an abstract class represents a slave system in Parallel Processing System, connected with this master system. This ParallelSystem takes full charge of network communication with the remote, parallel slave system has connected.

When a parallel process is requested (by ParallelSystemArray.sendSegementData or ParallelSystemArray.sendPieceData), the number of pieces to be allocated to a ParallelSystem is turn on its performance index. Higher performance index, then more pieces are requested. The performance index is revaluated whenever a parallel process has completed, basic on the execution time and number of pieces. You can sugguest or enforce the performance index with setPerformance or enforcePerformance.

Bridge & Proxy Pattern

This class ParallelSystem is derived from the ExternalSystem class. Thus, you can take advantage of the Bridge & Proxy Pattern in this ParallelSystem 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 Bridge & Proxy Pattern:

The ExternalSystem class can be a bridge for logical proxy. 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.
