DISABLING A PROCESSOR FACILITY ON A NEW PROCESSOR GENERATION WITHOUT BREAKING BINARY COMPATIBILITY - A simplified explanation of the abstract
This abstract first appeared for US patent application 17821832 titled 'DISABLING A PROCESSOR FACILITY ON A NEW PROCESSOR GENERATION WITHOUT BREAKING BINARY COMPATIBILITY
Simplified Explanation
The abstract describes a method, computer program product, and computer system for migrating a running logical partition (LPAR) between first-generation and second-generation computers, with different facilities available on each. The operating system detects the availability of required facilities and takes action to ensure orderly execution of the LPAR and its applications during migration.
- Migration of a running LPAR from a first-generation computer to a second-generation computer is performed.
- Operating system checks for availability of required facilities on the second-generation computer.
- Operating system takes action based on availability of required facilities to ensure orderly execution of the LPAR and its applications.
- Second migration of the LPAR from the second-generation computer back to the first-generation computer is performed.
- Operating system restores access to required facilities for the LPAR and its applications.
Potential Applications
- Data center management
- Cloud computing
- Virtualization technology
Problems Solved
- Seamless migration of running applications between different generations of computers
- Ensuring availability of required facilities during migration
Benefits
- Improved flexibility in managing computing resources
- Minimized downtime during migration
- Enhanced performance and efficiency in resource allocation
Original Abstract Submitted
Method, computer program product, and computer system are provided. A first migration of a running logical partition (LPAR) is performed from a first-generation computer to a second-generation computer. Availability of a facility differs between the first- and second-generation computers. Upon completion of the first migration, an operating system of the running LPAR detects whether a required facility in use on the first-generation computer is available on the second-generation computer. Operating system takes an action to continue an orderly execution of the LPAR, the operating system, and threads of an application in the LPAR depending on the availability of the required facility. A second migration is performed of the running LPAR from the second-generation computer back to the first-generation computer. The required facility is available on the first-generation computer. The operating system restores access to threads of the application to the required facility.
