Patent number: 9354870Abstract: A processor-implemented method, system, and/or computer program product maintain integrity of output of a code generator. One or more processors determine a generated output that has been generated by a specific code generation application based on an original model, where the original model is a structured model used to construct a software program. The generated output is analyzed to infer contents of an inferred version of the original model. The inferred version of the original model is compared with a current version of the original model to detect differences in source elements. Detected differences are thus used to identify redundant elements in the generated output.Type: GrantFiled: September 20, 2013Date of Patent: May 31, 2016Assignee: International Business Machines CorporationInventors: John A. Beaven, Rajasinghe S. Gunaratne, Robert J. Maddison

Patent number: 8281315Abstract: Exemplary embodiments include a system and storage medium for managing computer processing functions in a multi-processor computer environment. The system includes a physical processor, a standard logical processor, an assist logical processor sharing a same logical partition as the standard logical processor, and a single operating system instance associated with the logical partition, the single operating system instance including a switch-to service and a switch-from service. The system also includes a dispatch component managed by the single operating system instance. Upon invoking the switch-to service by standard code, the switch-to service checks to see if an assist logical processor is online and, if so, it updates an integrated assist field of a work element block associated with the task for indicating the task is eligible to be executed on the assist logical processor. The switch-to service also assigns a work queue to the work element block.Type: GrantFiled: April 3, 2008Date of Patent: October 2, 2012Assignee: International Business Machines CorporationInventors: Donald F. Ault, Jose R. Castano, Jeffrey P. Kubala, Robert J. Maddison, Bernard R. Pierce, Gary S. Puchkoff, Peter J. Relson, Robert R. Rogers, Donald W. Schmidt, Leslie W. Wyman

Patent number: 7392524Abstract: Exemplary embodiments include a method, system, and storage medium for managing computer processing functions in a multi-processor computer environment that includes a standard logical processor and an assist logical processor, each of which share the same operating system instance within a logical partition. The method includes invoking a switch-to service by standard code. The standard code is running on a standard logical processor and is executing a task. The switch-to service checks to see if an assist logical processor is online, and it if finds one, the switch-to service updates an integrated assist field of a work element block associated with the task and assigns a queue to the work element block. The task is dispatched, in accordance with business rules identified in a system control block, on either of said assist logical processor or said standard logical processor.Type: GrantFiled: April 6, 2004Date of Patent: June 24, 2008Assignee: International Business Machines CorporationInventors: Donald F.
