A query operation is performed to obtain information for a select entity of a computing environment. The information includes boost information of one or more boost features currently available for the select entity. The one or more boost features are to be used to temporarily adjust one or more processing attributes of the select entity. The boost information obtained from performing the query operation is provided in an accessible location to be used to perform one or more actions to facilitate processing in the computing environment.

Query and update of processor boost information

Logical processor distribution across physical processors is provided. A set of logical processors of a number of logical processors defined for a particular logical partition of a plurality of active logical partitions is assigned to a physical processor chip having a greatest logical processor entitlement for the particular logical partition until no more logical processors can be assigned to that physical processor chip based on a logical processor entitlement of that physical processor chip being exhausted. Remaining logical processors of the number of logical processors defined for the particular logical partition are assigned to other physical processor chips of a plurality of physical processor chips assigned to the particular logical partition until all of the remaining logical processors have been assigned to a physical processor chip.

Distribution of over-configured logical processors

In an approach for managing physical processor usage of a shared memory buffer, a processor receives a request for memory. A processor receives a request for memory from a process running on a physical processor. A processor determines whether the request for memory is less than or equal to a pre-determined threshold, wherein the pre-determined threshold is based on characteristics of a server on which the physical processor resides, needs of the server, and a frequency of requests of each memory size. Responsive to determining the request for memory is greater than the pre-determined threshold, a processor identifies a node on which the physical processor resides. A processor identifies a memory buffer of a set of memory buffers allocated to the node on which the physical processor resides. A processor allocates the memory buffer.

Managing memory buffer allocation in multi-processor system

Embodiments of the present invention are directed to a computer-implemented method for process management. The method includes assigning a drawer and a physical processor to each element of a first ready queue pointer array, wherein each element of the first ready queue pointer array is configured to point to a memory address of a ready queue header. The method further includes assigning the drawer and the physical processor to each element of a second ready queue pointer array, wherein each element of the second ready queue pointer array is configured to point to the same ready queue header as a respective element of the first ready queue pointer array. The method further includes detecting that either a physical processor has become unavailable to process executable instructions or that a ready queue is empty. The method further includes allocating an available physical processor and a ready queue with executable instructions.
