Abstract: Techniques are disclosed for allocating a global memory space defined within physical memory devices into strided memory space(s) (SMS) and partition memory space(s) (PMS). In an embodiment, a SMS is mapped across all of the devices, and a PMS is mapped to a subset of the devices to ensure resource isolation between separate PMSs. Typically, a memory space is allocated in unit sizes. When the locations mapped to most of the SMS align to an integer number of the unit size, a common boundary can be formed between the SMS and the one or more PMSs in each of the devices. Such a boundary can advantageously minimize a region of locations that are not available for allocation in the global memory spaces. In an embodiment, when a strided allocation is not an integer number of the unit size, a remainder is mapped to locations for one or more PMSs.
