    摘要: Described are techniques for processing a request to access global memory. For a first processor included on a first of a plurality of boards connected by a fabric, a logical address is determined for a global memory location in a system global memory. A first physical address for the logical address is determined. It is determined whether the first physical address is included in a first global partition of the first board. If so, first processing is performed including updating a memory map to map a window of the first processor's logical address space to a physical memory segment located within the first global partition. Otherwise, if the first physical address is included in a second of the plurality of global partitions physically located on one of the plurality of boards other than said first board, second processing is performed to issue the request over the fabric.

    摘要: Described are techniques for partitioning memory. A plurality of boards is provided. Each of the plurality of boards includes a physical memory portion and a set of one or more processor. The physical memory portion in each of said plurality of boards is partitioned into a plurality of logical partitions including a global memory partition accessible by any processor on any of the plurality of boards and one or more other memory partitions configured for use by one or more processors of said each board. Each of the one or more other memory partitions not being accessible to a processor on a board other than said each board.
