Abstract: Hierarchical resource tree memory operations can include receiving, at a memory scheduler, an indication of a proposed modification to a value of a memory parameter of an object represented by a node of a hierarchical resource tree, wherein the proposed modification is made by a modifying entity, locking the node of the hierarchical resource tree by the memory scheduler, performing the proposed modification by the memory scheduler, wherein performing the proposed modification includes creating a working value of the memory parameter according to the proposed modification, determining whether the proposed modification violates a structural consistency of the hierarchical resource tree based on the working value, and replacing the value of the memory parameter with the working value of the memory parameter in response to determining that the proposed modification does not violate a structural consistency of the hierarchical resource tree based on the working value, and unlocking the node of the hierarchical res

Abstract: Techniques for using non-volatile random access memory (NVM) as volatile random access memory (RAM) are provided. In one set of embodiments, a computer system can detect that an amount of free space in a volatile RAM of the computer system has become low and, in response, can add one or more memory pages from an unused portion of an NVM of the computer system to the system's volatile RAM pool. Conversely, the computer system can detect that an amount of free space in the NVM has become low and, in response, can return the one or more memory pages from the volatile RAM pool back to the NVM.
