Patent number: 10013264Abstract: In an embodiment, a request is received for a first partition to execute on a first virtual processor. If the first physical processor is available at a first node, the first virtual processor is dispatched to execute at the first physical processor at the first node that is the home node of the first virtual processor. If the first physical processor is not available, a determination is made whether the first physical processor is assigned to a second virtual processor and a home node of the second virtual processor is not the first node. If the first physical processor is assigned to a second virtual processor and the home node of the second virtual processor is not the first node, execution of the second virtual processor is stopped on the first physical processor and the first virtual processor is dispatched to the first physical processor.Type: GrantFiled: September 9, 2015Date of Patent: July 3, 2018Assignee: International Business Machines CorporationInventors: Stuart Z.
