Hypervisor-based management of local and remote virtual memory pages
A system and method is illustrated for comparing a target memory address and a local memory size using a hypervisor module that resides upon a compute blade, the comparison based upon a unit of digital information for the target memory address and an additional unit of digital information for the local memory size. Additionally, the system and method utilizes swapping of a local virtual memory page with a remote virtual memory page using a swapping module that resides on the hypervisor module, the swapping based upon the comparing of the target memory address and the local memory size. Further, the system and method is implemented to transmit the local virtual memory page to a memory blade using a transmission module that resides upon the compute blade.
1. A non-transitory computer-readable storage medium having computer-executable instructions stored thereon and executable by a processor to:
compare a target memory size and a local memory size using a hypervisor module that resides upon a compute blade, the comparison based upon a unit of digital information for the target memory size and an additional unit of digital information for the local memory size;
swap a local virtual memory page with a remote virtual memory page via a communication channel passing through a backplane using a swapping module that resides on the hypervisor module, the swapping based upon the comparing of the target memory size and the local memory size;
overwrite a victim page of the compute blade with the swapped remote virtual memory page, wherein the victim page is selected by the hypervisor module;
store data of the victim page of the compute blade via a temporary page on the compute blade; and
transmit the local virtual memory page to a memory blade via the communication channel passing through the backplane using a transmission module that resides upon the compute blade.
2. The non-transitory computer-readable storage medium of claim 1 , further comprising computer-executable instructions stored thereon and executable by a processor to receive the remote virtual memory page from the memory blade, using a receiving module that resides on the compute blade.
3. The non-transitory computer-readable storage medium of claim 1 , wherein the local memory size is defined by an operating system managed by the hypervisor module, the operating system residing on the compute blade.
4. The non-transitory computer-readable storage medium of claim 1 , further comprising computer-executable instructions stored thereon and executable by a processor to swap the remote virtual memory page with a temporary local virtual memory page using the swapping module that resides on the hypervisor module, the swapping based upon the comparing of the target memory size and the local memory size.
5. The non-transitory computer-readable storage medium of claim 1 , further comprising computer-executable instructions stored thereon and executable by a processor to:
identify the remote virtual memory page as a super page using a page identification module residing on the hypervisor module;
process a portion of the super page using an optimization module residing on the hypervisor module; and
execute an application managed by an operating system managed by the hypervisor module, the execution including processing the portion of the super page as an instruction set for the application.
6. The non-transitory computer-readable storage medium of claim 1 , wherein the memory blade includes a logical architecture with at least one of a protocol agent, a memory controller, address mapping, and accelerators.
7. The non-transitory computer-readable storage medium of claim 6 , wherein the address mapping is based upon considerations including at least one of electrical power consumption, and thermal generation.
