Embodiments described herein provide an apparatus comprising a processor to reserve a block of physical memory communicatively coupled to a processor, allocate a first portion of the block of physical memory for use with one or more processes executing on the processor, the first portion configured as a single memory page having a first page size, and in response to a determination that an amount of physical memory required by the one or more processes executing on the processor exceeds a first threshold allocate additional memory to the first portion of the block of physical memory, and increase the single memory page from a first page size to a second page size. Other embodiments may be described and claimed.

Translation lookaside buffer to implement adapative page size

In an embodiment, a first portion of a cache memory is associated with a first core. This first cache memory portion is of a distributed cache memory, and may be dynamically controlled to be one of a private cache memory for the first core and a shared cache memory shared by a plurality of cores (including the first core) according to an addressing mode, which itself is dynamically controllable. Other embodiments are described and claimed.

Method, apparatus and system for dynamically controlling an addressing mode for a cache memory

Systems and methods for managing shared cache by multi-core processor. An example processing system comprises: a plurality of processing cores, each processing core communicatively coupled to a last level cache (LLC) slice; and a cache control logic coupled to the plurality of processing cores, the cache control logic configured to perform one of: making an LLC slice of an inactive processing core available to an active processing core or power gating the LLC slice, based on estimating cache requirements by active processing cores.

Managing shared cache by multi-core processor

A method of an aspect includes running a plurality of threads on a plurality of thread processors. Memory accesses, of a thread of the plurality that is running on a first thread processor of the plurality, are monitored to both a first memory through a first memory controller and a second memory through a second memory controller. A second thread processor of the plurality is selected for a thread based on the monitoring of the memory accesses of the thread to both the first memory and the second memory. Installation of the thread, for which the second thread processor was selected, is initiated on the second thread processor. Other methods, apparatus, and systems are also disclosed.
