摘要： A fork system call by a first process is detected. A second process is created as a replication of the first process with a second affinity. If a replication of the replicated shared library is present in the second affinity domain, effective addresses of the replication of the replicated shared library are mapped using a mapping mechanism of the present invention to physical addresses in the second affinity domain.

摘要： An approach is provided that retrieves a time spent value corresponding to a selected partition that is selected from a group of partitions included in a virtualized environment running on a computer system. The virtualized environment is provided by a Hypervisor. The time spent value corresponds to an amount of time the selected partition has spent processing interrupts. A number of virtual CPUs have been assigned to the selected partition. The time spent value (e.g., a percentage of the time that the selected partition spends processing interrupts) is compared to one or more interrupt threshold values. If the comparison reveals that the time that the partition is spending processing interrupts exceeds a threshold, then the number of virtual CPUs assigned to the selected partition is increased.

摘要： A method of dynamically reallocating memory affinity in a virtual machine after migrating the virtual machine from a source computer system to a destination computer system migrates processor states and resources used by the virtual machine from the source computer system to the destination computer system. The method maps memory of the virtual machine to processor nodes of the destination computer system. The method deletes memory mappings in processor hardware, such as translation lookaside buffers and effective-to-real address tables, for the virtual machine on the destination computer system. The method starts the virtual machine on the destination computer system in virtual real memory mode. A hypervisor running on the destination computer system receives a page fault and virtual address of a page for said virtual machine from a processor of the destination computer system and determines if the page is in local memory of the processor. If the hypervisor determines the page to be in the local memory of the processor, the hypervisor returning a physical address mapping for the page to the processor. If the hypervisor determines the page not to be in the local memory of the processor, the hypervisor moves the page to local memory of the processor and returns a physical address mapping for said page to the processor.

摘要： A system and method for improving dynamic memory removals by reducing the file cache size prior to the dynamic memory removal operation initiating are provided. In one exemplary embodiment, the maximum amount of physical memory that can be used to cache files is reduced prior to performing a dynamic memory removal operation. Reducing the maximum amount of physical memory that can be used to cache files causes the page replacement algorithm to aggressively target file pages to bring the size of the file cache below the new maximum limit on the file cache size. This results in more file pages, rather than working storage pages, being paged-out.

摘要： A method manages memory paging operations. Responsive to a request to page out a memory page from a shared memory pool, the method identifies whether a physical space within one of a number of paging space devices has been allocated for the memory page. If physical space within the paging space device has not been allocated for the memory page, a page priority indicator for the memory page is identified. The memory page is then allocated to one of a number of memory pools within one of the number of paging space devices. The memory page is allocated one of the memory pools according to the page priority indicator of the memory page. The memory page is then written to the allocated memory pools.

摘要： In a multiprocessor system where each processor has the capacity to executing multiple hardware threads, a processor capacity monitor calculates a logical usage percentage of each of the available hardware threads. The processor capacity monitor calculates a physical usage percentage of each of the processors by each of the available threads. The processor capacity monitor calculate a percentage usage of a total capacity of the physical processors from the logical usage percentages and the physical usage percentages, such that the percentage usage reflects the actual use of the physical processors independent of which of the threads is used.

摘要： Associativity of a multi-core processor cache memory to a logical partition is managed and controlled by receiving a plurality of unique logical processing partition identifiers into registration of a multi-core processor, each identifier being associated with a logical processing partition on one or more cores of the multi-core processor; responsive to a shared cache memory miss, identifying a position in a cache directory for data associated with the address, the shared cache memory being multi-way set associative; associating a new cache line entry with the data and one of the registered unique logical processing partition identifiers; modifying the cache directory to reflect the association; and caching the data at the new cache line entry, wherein said shared cache memory is effectively shared on a line-by-line basis among said plurality of logical processing partitions of said multi-core processor.
