Abstract: A system and method for web-based grid computing are disclosed herein. A method for web-based grid computing includes receiving a data component request from a node computer of a grid computing system. The request indicates that the node computer is configured to process the data component as a part of the grid computing system. A data component is sent to the node computer in response to the request. The data component is configured to be processed by a grid computing system web-based processing program executing in a web browser of the node computer. A grid computing client program is provided that is included on a web page accessed by the node computer. The client program is configured to be executed in the web browser of the node computer, and when executed causes the node computer to operate as a part of the grid computing system.
