Abstract
A computer system on a network uses IP multicast to recruit other computer stems to share in the processing of a job. If a computer system on the network wants to be available to process shared jobs, it first registers for job sharing by invoking an IP multicast router at a particular IP address. All messages sent to the IP multicast router are broadcast to all computer systems that are registered with the router. When a computer system has ajob to share, it recruits other computer systems to help process the job by sending a message to the IP multicast router that corresponds to a request to share the job. The candidate computer systems that receive the recruiter's broadcast determine if they can share the job according to one or more job sharing parameters. These parameters may relate to the job itself, network performance, security, or other criteria for sharing. If a computer system meets the parameters for taking on the particular job, it responds to the recruiter. If the recruiter still needs help (e.g., if not enough candidate systems have responded yet), the recruiter grants the response and delivers the job to the computer system. The computer system then performs the job (or task) and returns the results to the recruiter.
