Allocating tasks by sending task-available messages requesting assistance with an image processing task from a server with a heavy task load to all other servers connected to the computer network
A plurality of server computers connected to computer network processes tasks that are unequally distributed among the server computers. A server sends a task-available message over the computer network to the remaining server computers to request assistance. The received task-available message is processed by some of the servers while others of the servers do not process the message because they are too busy. The servers that process the message respond by requesting a task from the message sending server.
1. A computer system for allocating computing tasks in a computer network, the computer system comprising:
a plurality of server computers, each including at least one hardware element and each connected to the computer network, wherein the plurality of server computers receives variable loads of computing tasks from a plurality of different sources connected to the computer network;
software on each server computer adapted to send task-available messages over the computer network to all other server computers connected to the computer network, wherein a task available message requests assistance with processing a computing task and wherein a server computer sends a task-available message when it has a heavy task load;
software on each server computer adapted to receive task-available messages;
software on each server computer adapted to process task-available messages, wherein for each task-available message, a first group of receiving server computers processes the task-available message and a second group of receiving server computers fails to process the task-available message; and
software on each server computer adapted to respond to processed task-available messages by requesting a task from a server computer that sends a task-available message.
2. The computer system of claim 1 , wherein the second group of receiving server computers fails to process the task-available message because the second group of receiving server computers have a heavy task load.
3. The computer system of claim 1 , wherein the first group of receiving server computers processes the task-available message because the first group of receiving server computers have a light task load.
4. The computer system of claim 1 , wherein the computing tasks are image-rendering tasks.
5. The computer system of claim 1 , wherein a first server computer sends a first task-available message and a second task-available message consecutively to all other server computers.
6. The computer system of claim 5 , wherein a first group of the other server computers processes the first task-available message, wherein a second group of the other server computers processes the second task-available message, and wherein the first group of the other server computers is not the same as the second group of the other server computers.
7. The computer system of claim 1 , wherein a first server computer sends a first task-available message to a first set of remaining server computers, wherein a second server computer sends a second task-available message to a second set of remaining server computers, wherein the first set of remaining server computers comprises all server computers connected to the computer network except the first server computer, and wherein the second set of remaining server computers comprises all server computers connected to the computer network except the second server computer.
8. The computer system of claim 7 , wherein at least one of the first set of remaining server computers processes and responds to the first task-available message, and wherein at least one of the second set of remaining server computers processes and responds to the second task-available message.
9. The computer system of claim 8 , wherein the at least one of the first set of remaining server computers that processes and responds to the first task-available message is not the same as the at least one of the second set of remaining server computers that processes and responds to the second task-available message.
10. The computer system of claim 1 , wherein each of the plurality of different sources provides work to one of the plurality of server computers independently.
11. The computer system of claim 10 , wherein the one or more different sources are remote client computers on the computer network.
12. The computer system of claim 1 , wherein the server computers have similar computing attributes.
13. The computer system of claim 1 , wherein the server computers have dissimilar computing attributes.
14. The computer system of claim 1 , wherein the computer network is the internet.
15. The computer system of claim 1 , further comprising software on each server computer adapted to allocate a computing task to any other server computer that responds to a task-available message.
16. A computer system for allocating computing tasks in a computer network, the computer system comprising:
a first server computer connected to the computer network, comprising at least one hardware component, wherein the server computer is adapted to receive a task-available message sent over the computer network from a second server computer, and wherein the task-available message requests assistance with processing a computing task; and
a program on the first server computer adapted to process the task-available message and respond to the task-available message by sending a request for a computing task over the computer network to the second server computer, wherein the program is further adapted not to respond to the task-available message if the first server computer includes a stored queue of pending tasks.
