摘要： According to the present invention, pool allocation and process assignment mechanisms create process nodal affinity in a NUMA multiprocessor system for enhanced performance. The multiprocessor system includes multiple interconnected multiprocessing nodes that each contain one or more processors and a local main memory, the system main storage being distributed among the local main memories of the multiprocessing nodes in a NUMA architecture. A pool reservation mechanism reserves pools of memory space within the logical main storage, and the pool allocation mechanism allocates those pools to real pages in the local main-memory of multiprocessing nodes. Processes to be created on the multiprocessor are given an attribute that indicates an associated pool. Upon creation, the process assignment mechanism will only assign a process to a multiprocessing node that has been allocated the pool indicated by the process' attribute. This process nodal affinity increases accesses by the assigned process to local main storage of that node, thereby enhancing system performance.

摘要： An apparatus and method provide simultaneous local and global addressing capabilities in a computer system. A global address space is defined that may be accessed by all processes. In addition, each process has a local address space that is local (and therefore available) only to that process. An address space processor is implemented in software to perform system functions that distinguish between local addresses and global addresses. In the preferred embodiments, the local address space has a size that is a multiple of the size of a segment of global address space. When the hardware indicates a page fault, the address space processor determines whether the address being translated is a local address or a global address. If the address is a local address, the address space processor uses a local directory to process the page fault. If the address is a global address, the address space processor uses a global directory to process the page fault. When the hardware indicates an addressing error because a computed address crosses a global segment boundary, the address space processor determines whether the address is a local address or a global address. If the address is a global address, the address space processor indicates an addressing error. If the address is a local address, the address space processor determines whether the address is within the process' local address space, and indicates an addressing error if the address is outside the process' local address space. Instructions are allowed to operate on both local and global addresses because the address space processor handles either type of address whenever software assistance is required, such as for servicing a page fault or checking a segment boundary crossing. In addition, the address space processor dynamically checks the addressing compatibility of called code before passing control to the called code.
