Distributed processing system and client node, server node and distributed processing method

In a distributed processing system including at least one client node and at least one server node for communicating with said at least one client node, each of said at least one client node comprising:

• task request means for generating a task request to said at least one server node to process a predetermined task;
• task program executing means for receiving a program for client execution of said requested predetermined task from said server node and executing said task in accordance with the content of a response signal returned from said at least one server node in response to said task request;
• and
• task result acquiring means for receiving one of the result of client execution of said program received from said server node and the result of said predetermined task executed by said server node.

In a distributed processing system including at least one server node and at least one requesting client node for communicating at least one task request for a predetermined task to said at least one server node, each of said at least one server node comprising:

• processing load measuring means for measuring the processing load of the server node;
• response means responsive to the measured processing load of the server node for returning to each requesting one of said at least one client node at least one response signal pertaining to said predetermined task;
• program sending means for sending the program for client execution of said predetermined task to each requesting one of said at least one client node when each requesting client node is to execute said predetermined task;
• and
• task executing means for executing said predetermined task and sending the result of server execution to each requesting one of said at least one client node.

In a distributed processing system comprising at least one client node and at least one server node, a dynamic distributed processing method comprising:

• the steps performed by each of said client nodes of;
• generating a task request to at least one server node to do a predetermined task;
• receiving a response signal from said server in response to said task request;
• receiving a program for client execution of said requested predetermined task from said server node when said task is to be executed at said client node in accordance with the content of said response signal;
• and
• receiving one of the result of client execution of said program received from said server node and the result of said predetermined task executed by said server node;
• and
• steps performed by said at least one server node of:
• measuring the processing load of said at least one server node;
• and
• generating at least one response signal to each requesting one of said at least one client node based on said measuring.

In a distributed processing system comprising at least one client node and at least one server node, a dynamic distributed processing method comprising at each client node the steps of:

• generating a task request to at least one server node to do a predetermined task;
• receiving a response signal from said server in response to said task request;
• receiving a program for executing said requested predetermined task from said server node when said task is to be for executed at said client node in accordance with the content of said response signal;
• and
• providing one of the result of execution at said client node of said program received from said server node and the result of said predetermined task as executed by said server node.

In a distributed processing system consisting of at least one client node and at least one server node, a computer readable recording medium recording a computer program for executing the steps of:

• generating a task request to at least one server node to do a predetermined task;
• receiving a response signal from said server in response to said task request;
• receiving a program for client execution of said requested predetermined task from said server node when said task is to be for executed at said client node in accordance with the content of said response signal;
• and
• providing one of the result of execution at said client node of said program received from said server node and the result of said predetermined task as executed by said server node.
