Abstract: A method and apparatus for a mechanism for handling explicit writeback in a cache coherent multi-node architecture is described. In one embodiment, the invention is a method. The method includes receiving a read request relating to a first line of data in a coherent memory system. The method further includes receiving a write request relating to the first line of data at about the same time as the read request is received. The method further includes detecting that the read request and the write request both relate to the first line. The method also includes determining which request of the read and write request should proceed first. Additionally, the method includes completing the request of the read and write request which should proceed first.

Abstract: An approach for pipelining ordered input/output transactions to coherent memory in a distributed memory, cache coherent, multi-processor system. A prefetch engine prefetches data from the distributed, coherent memory in response to a transaction from an input/output bus directed to the distributed, coherent memory. An input/output coherent cache buffer receives the prefetched data and is kept coherent with the distributed, coherent memory and with other caching agents in the system.

Abstract: A dynamic reconfiguration to include on-line addition, deletion, and replacement of individual modules of to support dynamic partitioning of a system, interconnect (link) reconfiguration, memory RAS to allow migration and mirroring without OS intervention, dynamic memory reinterleaving, CPU and socket migration, and support for global shared memory across partitions is described. To facilitate the on-line addition or deletion, the firmware is able to quiesce and de-quiesce the domain of interest so that many system resources, such as routing tables and address decoders, can be updated in what essentially appears to be an atomic operation to the software layer above the firmware.

Abstract: Multiple initialization techniques for system and component in a point-to-point architecture are discussed. Consequently, the techniques allow for flexible system/socket layer parameters to be tailored to the needs of the platform, such as, desktop, mobile, small server, large server, etc., as well as the component types such as IA32/IPF processors, memory controllers, IO Hubs, etc. Furthermore, the techniques facilitate powering up with the correct set of POC values, hence, it avoids multiple warm resets and improves boot time. In one embodiment, registers to hold new values, such as, Configuration Values Driven during Reset (CVDR), and Configuration Values Captured during Reset (CVCR) may be eliminated. For example, the POC values could be from the following: Platform Input Clock to Core Clock Ratio, Enable/disable LT, Configurable Restart, Burn In Initialization Mode, Disable Hyper Threading, System BSP Socket Indication, and Platform Topology Index.

Abstract: A method and apparatus for a mechanism for handling i/o transactions with known transaction length to coherent memory in a cache coherent multi-node architecture is described. In one embodiment, the invention is a method. The method includes receiving a request for a current copy of a data line. The method further includes finding the data line within a cache-coherent multi-node system. The method also includes copying the data line without disturbing a state associated with the data line. The method also includes providing a copy of the data line in response to the request. The method also includes determining if the data line is a last data line of a transaction based on a known transaction length of the transaction.

Abstract: Embodiments of the present invention relate to methods and apparatus for managing transaction requests in a multi-node architecture. In one embodiment, a previously received ordered group request may be forwarded to a destination agent. Whether a next received ordered group request belongs to a same ordered group as the previously received ordered group request may be determined. Additionally, it may be determined whether an ordering fork is encountered if the next received ordered group request belongs to the same ordered group as the previously received ordered group request. If an ordering fork is encountered, it may be determined whether a request complete message for the previously received ordered group request has been received.

Abstract: An apparatus and process for separating a feed liquefied natural gas containing at least methane and a hydrocarbon less volatile the methane, into a product natural gas enriched with methane and lean in hydrocarbon less volatile than methane and a heavier fraction lean in methane and enriched with hydrocarbon less volatile than methane. The process includes heating the feed liquefied natural gas in a heat exchanger, passing the heated fluid into a distillation column, withdrawing the heavier fraction from a bottom of the column, and withdrawing a residue gas from a top of the column. The process also includes liquefying at least part of the residue gas in the heat exchanger, refluxing a part of the liquid portion of the fluid obtained in the liquefying step into the column, and withdrawing, as the product narutal gas, the remainder of the liquid portion.

Abstract: In some embodiments an apparatus includes a transmission error detector to detect an error of a transmission of an interconnect and a transmitting agent to retry the transmission in response to the detected error. The apparatus also includes a hard failure detector to detect a hard failure of the interconnect if the retry is unsuccessful, and a transmission width reducer to reduce a transmission width of the interconnect in response to the hard failure detector. Other embodiments are described and claimed.

Abstract: The current method and apparatus provides a novel approach to manage the power consumption of a high speed I/O interface by selectively turning off non-essential portions of the interface. Here only part of the interface is powered off as compared to the whole interface being turned off. From the upper layers (protocol/system) perspective, the interface is always “on”. Thus, this mechanism reduces link power by selectively turning off portions of the link, yet allowing for fast wake up in an interface power management architecture.

Abstract: A method and apparatus are described for providing an implicit write-back in a distributed shared memory environment implementing a snoop based architecture. A requesting node submits a single read request to a snoop based architecture controller switch. The switch recognizes that another node other than the requesting node and the home node for the desired data has a copy of the data. The switch directs the request to the responding node that is not the home node. The responding node, having modified the data, provides a single response back to the switch that causes the switch to both update the data at the home node and answer the requesting node. The updating of the data at the home node is done without receiving an explicit write instruction from the requesting node.

Abstract: Systems and methods of retraining a receiver provide for determining a minimum transition density for a derived clock data link to the receiver. A retraining flit is generated based on the minimum transition density. In one approach, the retraining flit is generated by defining control data and payload data for the retraining flit. Error detection data is determined for the retraining flit based on the control and the payload data. The control data, the payload data and the error detection data have sufficient transitions to meet the minimum transition density.

Abstract: A method of sending messages from a node to a receiving agent. In one embodiment, if a outbound message that is stored in a buffer in the node is unsuccessfully sent to the receiving agent more than a threshold number of times, outbound messages currently stored in the buffer are sent to the receiving agent. It is determined that these outbound messages have been successfully sent before any other outbound messages are sent to the receiving agent. In a further embodiment, an outbound message is successfully sent if a success confirmation message is received for the outbound message from the receiving agent. In a still further embodiment, a retry response is received from the receiving agent for an outbound message if a buffer in the receiving agent that stores incoming outbound messages does not have room for the outbound message.
