Abstract: Dynamically provisionable and allocatable memory external to a requesting apparatus may be provided. A method includes: receiving a memory allocation request for allocating primary memory from a component of the client device; in response to the memory allocation request, selecting a subset of a region of memory in a memory device to be a portion of primary memory allocated for the client device, wherein the region of memory in the memory device is allocated for the client device before the memory allocation request is received; mapping at least the portion of primary memory to an address space; and accessing, by a hardware-accessible interface of the client device, data in the portion of primary memory via a client-side memory access, wherein a communication interface of the memory device is configured to access the subset of the region of memory in the memory device as part of the client-side memory access.

Abstract: Dynamically provisionable and allocatable memory external to a requesting apparatus may be provided. A request for primary memory may be made by an application executing on a client. An allocation logic unit may determine an allocation strategy in response to the request. As part of the allocation strategy, the allocation logic unit may identify memory appliances on which memory regions are to be allocated. The allocated memory regions may form the primary memory that is allocated to the requesting application. The allocation logic unit may send region allocation requests to region access unit of the respective memory appliances. The memory appliances on which the memory regions are allocated may be external to the client. The application may access the allocated memory regions via client-side access in which one or more processors in the client and/or the memory appliances are bypassed.

An example method includes: allocating, for an application logic, a region of external primary memory included in a memory appliance; selecting, by a client device in response to a first request to reclaim a first portion of local primary memory in the client device, a portion of external primary memory from the region of external primary memory; copying data from the first portion of local primary memory to the portion of external primary memory; and converting a portion of a first virtual address space at the client device by remapping at least one virtual address in the first virtual address space at the client device from the first portion of local primary memory to the portion of external primary memory.

Abstract: Methods and systems are provided for allocating memory. A portion of memory may be allocated by: selecting a type of memory to allocate in a client device from a group of memory types in response to a memory allocation request and/or in response to a request to access a portion of an address space, wherein the selection of the type of memory to allocate is based on an available memory determination; selecting a portion of the local primary memory, a portion of the external primary memory, or a portion of the memory-mapped file for the portion of memory to allocate at the client device depending on the selected type of memory; and mapping at least the selected portion to the address space.

Abstract: A mesh networked site process management system and method that provides for enforcement of a predefined access methodology by utilizing mesh networking through all possible touchpoints within a site perimeter and compound. Certain embodiments of the present disclosure comprise various computerized components communicably connected via a highly secured mesh network, in which only approved devices are able to participate on a machine-to-machine basis. The network may allow each device to coordinate its activity state with all other devices in the network. If a user desires to interact with one or more devices in the network, then the user must follow agreed upon process steps in order to do so. The user interacts with each network authorized device via a separate communication outside of the highly secured mesh network in order to transfer data to and from each network authorized device for the purposes of electronic access control.

A memory appliance and the first client device are connected by a network. A region of memory of the memory appliance may be allocated as external memory prior to receipt of the request to allocate the portion of memory at the first client device. A subset of the region of memory for the portion of memory allocated may be selected at the first client device and in coordination with a second client device on the network, wherein the portion of memory allocated is external to the first client device and yet is primary memory to the first client device. At least the subset of the region of memory may be mapped at the first client device to a virtual address space.
