摘要： An information handling system (IHS) loads an application that may include startup code and steady state operation code. The IHS allocates one region of system memory to the startup code and another region of system memory to the steady state operation code. A programmer inserts a memory release call command at a location that marks the end of execution of the startup code. After executing the startup code, the operation system receives the memory release call command. In response to the memory release call command, the operating system releases or de-allocates the region of memory to which the IHS previously assigned to the startup code. This enables the released memory for use by code other than the startup code, such as other code pages, library pages and other code.

摘要： A method, system, and computer usable program product for selective memory compression for multi-threaded applications are provided in the illustrative embodiments. An identification of a memory region that is shared by a plurality of threads in an application is received at a first entity in a data processing system. A request for a second entity in the data processing system to keep the memory region uncompressed when compressing at least one of a plurality of memory regions that comprise the memory region is provided from the first entity to the second entity.

摘要： Distributing a thread for running on a physical processor and enabling the physical processor to be switched into a low power snooze state when said running thread is IDLE. However, this switching into said low power state is enabled to be delayed by a delay time from an IDLE dispatch from said running thread; such delay is determined by tracking the rate of the number of said IDLE dispatches per processor clock interval and dynamically varying said delay time wherein the delay time is decreased when said rate of IDLE dispatches increases and the delay time is increased when said rate of IDLE dispatches decreases.

摘要： An operating system or virtual machine of an information handling system (IHS) initializes a resource manager to provide processor resource utilization management during workload or application execution. The resource manager captures short term interval (STI) and long term interval (LTI) processor resource utilization data and stores that utilization data within an information store of the virtual machine. If a capacity on demand mechanism is enabled, the resource manager modifies a reserved capacity value. The resource manager selects previous STI and LTI values for comparison with current resource utilization and may apply a safety margin to generate a reserved capacity or target resource utilization value for the next short term interval (STI). The hypervisor may modify existing virtual processor allocation to match the target resource utilization.
