Out of order job processing method and apparatus

摘要

A computer system executes steps to provide results in an order different from an intended order. Instructions are concatenated into a plurality of jobs. Different invocations of a variable within the computer instruction stream may be assigned respectively different storage locations and each storage location may correspond to a different job. When all the storage locations associated with a particular job indicate available resources (e.g. valid variable input), the job may be executed. A mechanism allows for job re-execution, if needed, due to interrupt or error.
