A method for operating a host layer of a distributed computing system on a wide area network includes attaching an autonomous agent to a client-requested carrier, such as web content. The method includes the steps of receiving a request for specified content from a client node via the wide area network, and sending the content and an embedded agent to the client via the wide area network. The agent has program instructions configured to execute autonomously on the client node to perform a processing function. The processing function is configured to operate on raw data to produce process data, according to instructions determined by a solution algorithm of the distributed computing system. The method further includes sending the raw data to the client node and receiving the process data from the client node as it is processed by the agent. The host layer may comprise a web server hosting a web site containing consumer-oriented web pages, and the carrier may comprise an HTML page containing user content. The agent may comprise a web page-enabled application embedded in the HTML page, such as a Java™ applet.
