Abstract
A system and corresponding method isolate work within a virtualized scheduler using tag-spaces. The system comprises a tag-space resource configured to store at least one respective assignment of at least one scheduling group to a given tag-space. The given tag-space defines a given ordering-atomicity domain that isolates, within the virtualized scheduler, (i) work belonging to the at least one scheduling group from (ii) work belonging to at least one other scheduling group, assigned, in the tag-space resource, to a respective tag-space different from the given tag-space. The system further comprises a work scheduler that schedules, for processing, work belonging to the at least one scheduling group and work belonging to the at least one other scheduling group. Such scheduling may have independent ordering and atomicity effectuated therebetween by the given ordering-atomicity domain. Such independency of ordering and atomicity improves quality-of-service of the virtualized scheduler.
