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.

A method and apparatus for saving and restoring architectural states utilizing hardware is described. A first portion of an architectural state of a processing element, such as a core, is concurrently saved upon being updated. A remaining portion of the architectural state is saved to memory in response to a save state triggering event, which may include a hardware event or a software event. Once saved, the state is potentially transferred to another processing element, such as a second core. As a result, hardware, software, or combination thereof may transfer architectural states between multiple processing elements, such as threads or cores, of a processor utilizing hardware support.

Provided are a method, system, and program for sharing data in a user virtual address range with a kernel virtual address range. A user address in a user address space and length defining a user address range referencing physical locations in a memory are received. A determination is made of determining at least one page in the memory including the physical locations referenced by the user address range. For each determined page, one kernel address in a kernel address space is generated to reference the determined page, wherein at least one user address and at least one kernel address reference one page in the memory.

A method and system for routing data across heterogeneous networks. In one embodiment, a heterogeneous network comprises a specialized in-band network that is privately accessible within the heterogeneous network, as well as an out-of-band network that is coupled to the in-band network by a switching platform. A client on the out-of-band network is configured to transmit a request for server data to the switching platform. The request is formatted according to the protocol of the out-of-band network and may take the form of a uniform resource locator (URL). The switching platform is configured to recognize the request as one which is directed to a server on the in-band network. The switching platform parses the request to determine the requested data and reformats this information as a new request that is transmitted to the server according to the protocol of the in-band network. The server provides data responsive to the new request, which is transmitted back to the switching platform according to the protocol of the in-band network. The switching platform then reformats the responsive data according to the protocol of the out-of-band network and transmits it to the client. The switching platform is separate from the default gateway and proxy servers.
