    摘要: A method and apparatus for enabling usage of an accelerator device in a processor socket is herein described. A set of inter-processor messages is utilized to initialize a configuration/memory space of the accelerator device. As an example, a first set of inter-processor interrupts (IPIs) is sent to indicate a base address of a memory space and a second set of IPIs is sent to indicate a size of the memory space. Furthermore, similar methods and apparatus' are herein described for dynamic reconfiguration of an accelerator device in a processor socket.

    摘要: In one embodiment, a method is provided. The method of this embodiment provides detecting by a network controller a flush occurring on a host bus of a DM (“direct messaging”) packet to a memory from a first cache line associated with a first processor; obtaining and storing the DM packet at a second cache line associated with the network controller; and sending the DM packet over a network to a third cache line associated with a second processor.

    摘要: A multiprocessor system comprises at least one processing module, at least one I/O module, and an interconnect network to connect the at least one processing module with the at least one input/output module. In an example embodiment, the interconnect network comprises at least two bridges to send and receive transactions between the input/output modules and the processing module The interconnect network further comprises at least two crossbar switches to route the transactions over a high bandwidth switch connection. Using embodiments of the interconnect network allows high bandwidth communication between processing modules and I/O modules Standard processing module hardware can be used with the interconnect network without modifying the BIOS or the operating system. Furthermore, using the interconnect network of embodiments of the present invention is non-invasive to the processor motherboard. The processor memory bus, clock, and reset logic all remain intact.
