    Abstract: PROBLEM TO BE SOLVED: To provide a method and a system for implementing logical partition of an input/output slot in a data processing system, and a computer.program product. SOLUTION: In one form of implementation, this system includes a hypervisor and at least one DMA address inspecting component. The hypervisor receives an indirect memory.access demand regarding access to an input/output slot, and prohibits a device in a certain logical section from accessing to an input/ output slot assigned to a different logical section. The DMA address inspecting component receives a direct memory.access demand, and prohibits completion of a demand regarding an address which is not in the same logical section for the device of a requester. A demand regarding an address corresponding to the same logical section for the device of the requester is placed in a primary PCI bus by the DMA address inspecting component for transmission of a system.memory.

    Abstract: A method, apparatus and program for booting a non-uniform-memory-access (NUM A) machine are provided. The invention comprises configuring a plurality of standalone, symmetrical multiprocessing (SMP) systems to operate within a NU MA system. A master processor is selected within each SMP; the other processors in the SMP are designated as NUMA slave processors. A NUMA master processor is then chosen from the SMP master processors; the other SMP master processors are designated as NUMA slave processors. A unique NUMA ID is assigned to eac h SMP that will be part of the NUMA system. The SMPs are then booted in NUMA mode in one-pass with memory coherency established right at the beginning of the execution of the system firmware.
