The prioritization of large memory page mapping is a function of the access bits in the L1 page table. In a first phase of operation, the number of set access bits in each of the L1 page tables is counted periodically and a current count value is calculated therefrom. During the first phase, no pages are mapped large even if identified as such. After the first phase, the current count value is used to prioritize among potential large memory pages to determine which pages to map large. The system continues to calculate the current count value even after the first phase ends. When using hardware assist, the access bits in the nested page tables are used and when using software MMU, the access bits in the shadow page tables are used for large page prioritization.

System and method to prioritize large memory page allocation in virtualized systems

A system and related method of operation for migrating the memory of a virtual machine from one NUMA node to another. Once the VM is migrated to a new node, migration of memory pages is performed while giving priority to the most utilized pages, so that access to these pages becomes local as soon as possible. Various heuristics are described to enable different implementations for different situations or scenarios.

System and method for improving memory locality of virtual machines

A method and system for executing a software application having a binary size that is larger than an available memory space in an embedded system from which the software application will execute. The software application is split into one or more initialization sequences and a main code sequence. The method includes loading () each initialization sequence of the one or more initialization sequences in the memory space prior to its execution, and executing () each initialization sequence of the one or more initialization sequences out of the memory space. Further, the method includes loading () the main code sequence in the memory space after the execution of the one or more initialization codes and then executing () the main code sequence out of the memory space.
