Patent number: 11662934Abstract: A data processing system includes a system fabric, a system memory, a memory controller, and a link controller communicatively coupled to the system fabric and configured to be communicatively coupled, via a communication link to a destination host with which the source host is non-coherent. A plurality of processing units is configured to execute a logical partition and to migrate the logical partition to the destination host via the communication link. Migration of the logical partition includes migrating, via a communication link, the dataset of the logical partition executing on the source host from the system memory of the source host to a system memory of the destination host. After migrating at least a portion of the dataset, a state of the logical partition is migrated, via the communication link, from the source host to the destination host, such that the logical partition thereafter executes on the destination host.Type: GrantFiled: December 15, 2020Date of Patent: May 30, 2023Assignee: International Business Machines CorporationInventors: Steven Leonard Roberts, David A. Larson Stanton, Peter J. Heyrman, Stuart Zachary Jacobs, Christian Pinto

Patent number: 11347410Abstract: A computing device, a non-transitory computer readable storage medium, and a method are provided for automatically recreating lost storage volumes. A volume command including volume metadata associated with a storage volume of an SCM storage device is received. The volume metadata is stored at another storage device that is less volatile than the SCM storage device. The storage volume is configured in accordance with the volume command including forwarding the volume command to an SCM device driver. A notification of a persistence loss at the SCM storage device is received subsequent to forwarding the volume command. The volume metadata is retrieved from the other storage device subsequent to receiving notification of the persistence loss. The storage volume is automatically re-configured in accordance with the volume command including submitting the retrieved volume metadata to the SCM device driver.Type: GrantFiled: February 13, 2021Date of Patent: May 31, 2022Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: James Long, Michael James Vance, Justin King, David A.

Patent number: 10776281Abstract: An apparatus for bypassing an invalidate search of a lookaside buffer includes a filter circuit that directs an invalidate command to a LPID/PID filter of an MMU of a processor and searches for an identifier targeted by the invalidate command. The MMU is external to cores of the processor. The apparatus includes an LPID/PID miss circuit that bypasses searching the lookaside buffer for addresses targeted by the invalidate command and returns a notification that the invalidate command did not identify the identifier targeted by the invalidate command in response to the filter circuit determining that the identifier targeted by the invalidate command is not stored in the LPID/PID filter.Type: GrantFiled: October 4, 2018Date of Patent: September 15, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Jake Truelove, Ronald Kalla, Jody Joyner, Benjamin Herrenschmidt, David A.

Patent number: 10216599Abstract: A program operating to test a computer has a limit to the number of certain components that it can utilize, less than the number of those components included in the computer. A resource allocator program receives a signal to modify allocation of resources to the programs executing in the computer. The resource allocator detects that the computer is operating in a mode for testing and selects a subset of the components not allocated to the program to swap for those presently allocated. The resource allocator can receive the signal repeatedly to complete testing the computer.Type: GrantFiled: May 26, 2016Date of Patent: February 26, 2019Assignee: International Business Machines CorporationInventors: Salim A. Agha, Peter J. Heyrman, David A. Larson Stanton, Fraser A. Syme

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.
