Abstract: A method for transferring memory pages to a first and a second page repository identifies pages in a memory sharing operation for transfer to a first page repository and pages in a memory migration operation for transfer to a second page repository. Pages in the memory migration operation may be prepared for transfer prior to transfer of the pages in the memory sharing operation. Transferring pages in the migration operation may remove the need to transfer pages in the memory sharing operation.

Abstract: A process and apparatus for quenching a hydrocracked stream to prepare it for hydroisomerization. A fractionated hydroisomerized stream is recycled to quench a hot hydrocracked stream prior to hydroisomerization. Sufficient quenching can inactivate the hydroisomerization catalyst bed. The hydroisomerization catalyst bed can be heated back to hydroisomerization temperature and can actively hydroisomerize again.

Abstract: Techniques are described for routing service requests in a computer-implemented service environment. A received service request may be initially analyzed to determine a priority of the request. In some implementations, one or more actions may be automatically performed to provide an initial response to the requester. The text of the request may be analyzed to automatically determine a category of the request. In some implementations, a classification engine may determine the category of the request through use of a classification model that has been trained using one or more machine learning (ML) techniques and/or that employs Natural Language Processing (NLP). Based on the category, the request may be routed to agent(s) for handling. Routing may include generating a ticket that includes the request, the category, the priority, and/or other information, and the ticket may be provided to the appropriate agent(s) through a ticketing service.

Abstract: A computer-implemented method includes identifying a page. The page is associated with a request for migration. The page is associated with a current page address. The method includes determining whether the page is associated with a previous page. The previous page is associated with a previous page address. The method is responsive to the page not being associated with a previous page. The method responds by marking the page as being for migration. The method is responsive to the page being associated with a previous page. The method responds by determining whether the previous page has been written to. The method is responsive to the previous page having been written to by marking the page as being for a mapping migration. The method is responsive to the previous page having not been written to by marking the page as not being for migration.

Abstract: As disclosed herein a method, executed by a computer, for enabling live partition mobility using ordered memory migration includes receiving a request to initialize a migration of a logical partition (LPAR) to a destination system. The method further includes creating a list which includes memory page identifiers corresponding to memory pages of the LPAR. The memory page identifiers of the list are ordered according to a page transfer priority. The method further includes identifying memory pages of the LPAR that will be unmodified during an estimated duration of time of the migration. The method further includes updating the list, based on the identified memory pages of the LPAR that will be unmodified during the estimated duration of time of the migration. The method further includes migrating the LPAR based on the list. A computer system, and a computer program product corresponding to the method are also disclosed herein.

Abstract: A method for transferring pages from a memory to a page repository identifies an affinity domain that associates processors and memory pages. The method further includes determining that a processor in an affinity domain is suspended and selecting pages included in that affinity domain to transfer prior to transferring pages in an affinity domain in which no processors are suspended.

Abstract: A prosthetic heart valve includes a collapsible and expandable stent extending from an inflow end to an outflow end and a plurality of prosthetic valve leaflets coupled to the stent. The prosthetic heart valve may also include a sealing ring coupled to the inflow end of the stent, the sealing ring comprising a tube extending circumferentially around the inflow end of the stent. The tube may be formed from a wire coiled into a repeating shape, such as a rectangle or a diamond, so that the tube is collapsible. A covering may at least partially surround the tube. The sealing ring may include a first filler positioned within the tube and/or a second filler positioned between the tube and the covering.

Abstract: A rule-based method for pre-fetching “important pages” from memory paging space back into kernel memory space performs the following steps: (i) establishing a first machine logic based rule, with the machine logic based rule including a first triggering condition and a first consequential responsive action; (ii) determining that the first triggering condition has occurred; and (iii) in response to the determination that the first triggering condition has occurred, performing the first consequential responsive action. The first triggering condition includes the following sub-conditions: (i) at least one of a first set of important page(s) of a computer system has been paged out of kernel memory space and into paging memory space, and (ii) a processing status of the computer system indicates that the first set of important page(s) will be likely to be required for computer operations.

Abstract: A physical address of a page may be identified. A first process that implements copy-on-read techniques for the page may be detected. A determination may be made that the first process is not expected to write to the page. In response to that determination, a different logical address may be established for the first process for the page from the logical address of a second process for the page, but the two logical addresses may be mapped to the same physical page.

Abstract: A page type may be identified for each of a plurality of memory pages, the page type corresponding to a particular process that accesses a particular memory page of the plurality of memory pages. The plurality of memory pages may each respectively include duplicate data. The duplicate data may be a same set of data values. Each of the plurality of respective memory pages may be ranked as candidates to deduplicate the set of data values to. The ranking may be based on at least the page type. In response to identifying the first processor and identifying a first memory device, the duplicate data may be deduplicated from the plurality of memory pages to a highest ranked memory page. The deduplication may correspond to coalescing the duplicate data to the highest ranked memory page.
