Abstract
A system and associated methods are disclosed for allocating memory in a system providing translation of virtual memory addresses to physical memory addresses in a parallel computing system using memory striping. One method comprises: receiving a request for memory allocation, identifying an available virtually-contiguous physically-non-contiguous memory region (VCPNCMR) of at least the requested size, where the VCPNCMR is arranged such that physical memory addresses for the VCPNCMR may be derived from a corresponding virtual memory addresses by shifting a contiguous set of bits of the virtual memory address in accordance with information in a matching row of a virtual memory address matching table, and combining the shifted bits with high-order physical memory address bits also associated with the determined matching row and with low-order bits of the virtual memory address, and providing to the requesting process a starting address of the identified VCPNCMR.
