Abstract: An elastomeric base for a pressure vessel is configured to be adhesively secured to the bottom of the vessel in order to eliminate the problems caused by welding of steel legs. The base includes a surface configured to correspond with a curved surface of the compressor vessel. Advantageously, the base may be formed of an elastomeric material, a plastic, or of an elastomeric material co-molded with a ridged plastic.

Abstract: The present invention provides an improved method, an system, and a set of computer implemented instructions for handling a cache containing multiple single-bit hard errors on multiple addresses within a data processing system. Such handles will prevent any down time by logging in the parts to be replaced by an operator when certain level of bit errors is reached. When a hard error exists on a cache address for the first time, serviceable first hard error, that cache line is deleted. Thus the damaged memory device is no longer used by the system. As a result, the system is running with “N?x” lines wherein “N” constitutes the total number of existing lines and “x” is less than “N”. An alternative method is to exchange the damaged memory device to a spare memory device. In order to provide such services, the system must first differentiate whether an error is a soft or hard error.

Abstract: A data processing system includes a requester having a request queue and a recipient. The requester, which buffers a request in an entry of the request queue, transmits the request to the recipient for servicing. According to the request-and-forget protocol, the requester removes the request from the entry of the request queue without receipt of any indication that the request has been serviced.

The collar (1) supported on the head by a harness (20) having two triangular portions (21) on opposite sides encircling respective ears.

Abstract: A computer system includes a home node and one or more remote nodes coupled by a node interconnect. The home node includes a local interconnect, a node controller coupled between the local interconnect and the node interconnect, a home system memory, a memory directory including a plurality of entries, and a memory controller coupled to the local interconnect, the home system memory and the memory directory. The memory directory includes a plurality of entries that each provide an indication of whether or not an associated data granule in the home system memory has a corresponding cache line held in at least one remote node. The memory controller includes demand invalidation circuitry that, responsive to a data request for a requested data granule in the home system memory, reads an associated entry in the memory directory and issues an invalidating command to at least one remote node holding a cache line corresponding to the requested data granule.

Abstract: A non-uniform memory access (NUMA) computer system includes at least one remote node and a home node coupled by a node interconnect. The home node contains a home system memory and a memory controller. In response to receipt of a data request from a remote node, the memory controller determines whether to grant exclusive or non-exclusive ownership of requested data specified in the data request by reference to history information indicative of prior data accesses originating in the remote node. The memory controller then transmits the requested data and an indication of exclusive or non-exclusive ownership to the remote node.

Abstract: A fenestration sealed frame insulating glazing panel has an integral planar frame formed by four rigid plastic profiles interconnected end-to-end to define corners, the profiles having a low heat conductivity. Two glazing sheets are arranged in a spaced parallel relationship attached on opposite sides of the frame in a rigid manner by thermosetting adhesive to form an integral structure having an insulating cavity enclosed by the frame. The front face of each frame profile facing towards the cavity is covered by a low permeability sealant. The sealed frame glazing panel can include a third glazing sheet positioned in parallel between the first two glazing sheets and likewise interconnected at its perimeter to the frame to divide the insulating cavity into two parallel coextensive sub-cavities. The profiles of the frame can be made from structural plastic foam material, glass fiber, oriented thermoplastic, or various other materials of low thermal conductivity.

Abstract: A data processing system includes a plurality of nodes, which each contain at least one agent and each have an associated node identifier, and memory distributed among the plurality of nodes. The data processing system further includes an interconnect containing a segmented data channel, where each node contains a segment of the segmented data channel and each segment is coupled to at least one other segment by destination logic. In response to snooping a write request of a master agent on the interconnect, a target agent that will service the write request places its node identifier in a snoop response. When the master agent receives the combined response, which contains the node identifier of the target agent, the master agent issues on the segmented data channel a write data transaction specifying the node identifier of the target agent as a destination identifier.

Abstract: A method and system for speculatively pre-fetching data from a memory. A memory controller on a data bus “snoops” data requests put on the data bus by a bus control logic. Based on information in the header of the data request, such as transaction type, tag, transaction size, etc., a speculative pre-fetch is made to read data from the memory associated with the memory controller. If the speculative fetch turns out to be correct, then the memory controller makes an assumption that the pre-fetch was too conservative (non-speculative), and a pre-fetch for a next data request is performed at an earlier more speculative time. If the speculative fetch turns out to be incorrect, then the memory controller makes an assumption that the pre-fetch was too speculative (made early), and a pre-fetch for a next data request is performed at a later less speculative time.

Abstract: Upon snooping an operation in which an intervention is permitted or required, an intervening cache may elect to source only that portion of a requested cache line which is actually required, rather than the entire cache line. For example, if the intervening cache determines that the requesting cache would likely be required to invalidate the cache line soon after receipt, less than the full cache line may be sourced to the requesting cache. The requesting cache will not cache less than a full cache line, but may forward the received data to the processor supported by the requesting cache. Data bus bandwidth utilization may therefore be reduced. Additionally, the need to subsequently invalidate the cache line within the requesting cache is avoided, together with the possibility that the requesting cache will retry an operation requiring invalidation of the cache line.

Abstract: A computer system includes a processing unit, a system memory, and a memory controller coupled to the processing unit and the system memory. According to the present invention, the memory controller accesses the system memory to obtain prefetch data and transmits the prefetch data to the processing unit in a prefetch write operation specifying the processing unit in a destination field. In one embodiment, the memory controller transmits the prefetch write operation in response to receipt of a prefetch hint from the processing unit, which may accompany a read-type request by the processing unit. This prefetch methodology may advantageously be implemented imprecisely, with the memory controller responding to the prefetch hint only if a prefetch queue is available and ignoring the prefetch hint otherwise. The processing unit may similarly ignore the prefetch write operation if no snoop queue is available.

Abstract: A non-uniform memory access (NUMA) computer system and associated method of operation are disclosed. The NUMA computer system includes at least a remote node and a home node coupled to an interconnect. The remote node contains at least one processing unit coupled to a remote system memory, and the home node contains at least a home system memory. To reduce access latency for data from other nodes, a portion of the remote system memory is allocated as a remote memory cache containing data corresponding to data resident in the home system memory. In one embodiment, access bandwidth to the remote memory cache is increased by distributing the remote memory cache across multiple system memories in the remote node.

Abstract: A non-uniform memory access (NUMA) computer system includes a first node and a second node coupled by a node interconnect. The second node includes a local interconnect, a node controller coupled between the local interconnect and the node interconnect, and a controller coupled to the local interconnect. In response to snooping an operation from the first node issued on the local interconnect by the node controller, the controller signals acceptance of responsibility for coherency management activities related to the operation in the second node, performs coherency management activities in the second node required by the operation, and thereafter provides notification of performance of the coherency management activities.

Abstract: Vibratory welded connections are formed between first and second members (32, 33) of thermoplastic material by interposing a junction piece (47) of similar material and vibrating the junction piece (47) at high speed while pressing the first and second members (32,33) in a controlled manner against opposite sides of the junction piece (47). Friction created by the vibration generates heat which melts a small amount of material at the engaging surfaces which upon cooling provides a strong welded joint having minimal flash. Entire frame systems such as window-frames can be fabricated by an apparatus system (120) which forms a friction welded joint between adjacent ends of the frame members (134, 135, 136, 137). Furthermore the frame can be fabricated around a panel such as a glazing panel. The welded connections formed by the system do not mar the finish of the frame members and produce no unsightly flash bead requiring subsequent machining steps for its removal.
