METHOD AND MEANS FOR CO-SCHEDULING JOB ASSIGNMENTS AND DATA REPLICATION IN WIDE-AREA DISTRIBUTED SYSTEMS

摘要

The embodiments of the invention provide a method, service, computer program product, etc. of co-scheduling job assignments and data replication in wide-area systems using a genetic method. A method begins by co-scheduling assignment of jobs and replication of data objects based on job ordering within a scheduler queue, job-to-compute node assignments, and object-to-local data store assignments. More specifically, the job ordering is determined according to an order in which the jobs are assigned from the scheduler to the compute nodes. Further, the job-to-compute node assignments are determined according to which of the jobs are assigned to which of the compute nodes; and, the object-to-local data store assignments are determined according to which of the data objects are replicated to which of the local data stores.
