Abstract: Entanglement of pages and threads is disclosed. An indication is received of a stalling event caused by a requested portion of memory being inaccessible. It is determined that the requested portion of memory is an entangled portion of memory that is entangled with a physical node in a plurality of physical nodes. A type of the entangled portion of memory is determined. The stalling event is handled based at least in part on the determined type of the entangled portion of memory.

Abstract: Dynamic adaptive reconfiguration of a computing system includes receiving a request to remove a first node in a plurality of physical nodes. An operating system is executing collectively across the plurality of physical nodes, and an application is running on the operating system. It further includes in response to the request, and while the application is running, evacuating virtualized resources associated with the first node to one or more other nodes in the plurality of physical nodes. It further includes subsequent to the evacuation of the virtualized resources, removing the first node from the plurality of physical nodes.

Abstract: Utilizing a storage replica data structure includes receiving, at a hyper-kernel running on a computing node in a plurality of interconnected computing nodes, an indication of an operation pertaining to at least one of a guest physical memory address or a stable storage address. A guest operating system is run on a virtual environment that is defined by a set of hyper-kernels running on the plurality of interconnected computing nodes. It further includes updating a storage replica data structure. The storage replica data structure comprises a set of entries. The set of entries in the storage replica data structure comprises associations among guest physical memory addresses, physical memory addresses, and stable storage addresses
