摘要:
A method of assigning web service requests to service providers includes searching for an optimal assignment from all possible assignments using a genetic algorithm (GA) that represents possible assignments as chromosomes, and converging towards an assignment of web service request to service providers that maximizes overall business value for all workflows to the service providers. An adaptive mutation scheme is used to introduce mutation into populations of chromosomes. The mutation scheme includes a mutation rate that increases when chromosomes under evaluation fail to improve its workload against the metric over a certain number of generations.
摘要:
A distributed job-processing environment including a server, or servers, capable of receiving and processing user-submitted job queries for data sets on backend storage servers. The server identifies computational tasks to be completed on the job as well as a time frame to complete some of the computational tasks. Computational tasks may include, without limitation, preprocessing, parsing, importing, verifying dependencies, retrieving relevant metadata, checking syntax and semantics, optimizing, compiling, and running. The server performs the computational tasks, and once the time frame expires, a message is transmitted to the user indicating which tasks have been completed. The rest of the computational tasks are subsequently performed, and eventually, job results are transmitted to the user.
