Abstract: Apparatus having a cache memory including cache lines configured to cache data sent from an input/output device and an eviction mechanism configured to evict data stored in one of the cache lines based on validity state information associated with the data stored in the one cache line. Each cache line has multiple portions, and validity bits are used to track the validity of respective portions of the cache line. The validity bits are set to predefined values responsive to the number of bytes written into the respective portions in one write transaction. The cache line is evicted by the eviction mechanism when the validity bits corresponding to the cache line all have the predefined values. The eviction mechanism is configured to evict the data even if the cache memory is not full.

Abstract: A curable composition including a polymer comprising, as copolymerized units, a monomer having carboxylic acid groups, anhydride groups, or salts thereof, and at least one of certain hydroxyl group-comprising monomers wherein the ratio of the number of equivalents of the carboxylic acid groups, anhydride groups, or salts thereof to the number of equivalents of the hydroxyl groups is from about 1/0.01 to about 1/3, and wherein the carboxylic acid groups, anhydride groups, or salts thereof are neutralized to an extent of less than about 35% with a fixed base is provided. Also provided is a method for treating a substrate with the curable composition and a substrate bearing the cured composition.

The pendant polymeric chains have terminal chain segments containing polyoxyalkylene units comprising 3 to 6 carbon atoms. The nonionic associative thickeners are useful for modifying the rheology of compositions including aqueous compositions, such as latex containing compositions.

Abstract: A technique to broadcast a message across a point-to-point network. More particularly, embodiments of the invention relate to broadcasting messages between electronics components within a point-to-point interconnect.

Abstract: An arrangement is provided for an external agent to initiate data prefetches from a system memory to a cache associated with a target processor, which needs the data to execute a program, in a computing system. When the external agent has data, it may create and issue a prefetch directive. The prefetch directive may be sent along with system interconnection transactions or sent as a separate transaction to devices including the target processor in the system. When receiving and recognizing the prefetch directive, a hardware prefetcher associated with the target processor may issue a request to the system memory to prefetch data to the cache. The target processor can access data in the cache more efficiently than it accesses data in the system memory. Some pre-processing may also be associated with the data prefetch.

Abstract: Systems and methods of managing transactions provide for receiving a first flush command at a first I/O hub, wherein the first flush command is dedicated to non-posted transactions. One embodiment further provides for halting an inbound ordering queue of the first I/O hub with regard to non-posted transactions in response to the first flush command and flushing a non-posted transaction from an outgoing buffer of the first I/O hub to a second I/O hub while the inbound ordering queue is halted with regard to non-posted transactions.

Abstract: In various embodiments, the present invention includes a method for receiving a transaction having first header information from a first peer device at a first agent of a coherent system, inserting second header information onto the transaction, and routing the transaction to a second peer device using the second header information. In one such embodiment, the first header may be a header of a first protocol and the second header may be of a different protocol that is used to tunnel the transaction through the coherent system.

Abstract: In one embodiment of the present invention, a method may include separating incoming transactions to an agent of a coherent system into at least a first channel, a second channel, and a third channel, based upon a type of the incoming transactions. The incoming transactions may be sent by a peer device coupled to the coherent system. By separating the transactions based on type, deadlocks may be avoided.

Abstract: In one embodiment of the present invention, a method includes identifying a transaction from a first processor to a second processor of a system with a transaction identifier. The transaction identifier may have a value that is less than or equal to a maximum number of outstanding transactions between the two processors. In such manner, a transaction field for the transaction identifier may be limited to n bits, where the maximum number of outstanding transactions is less than or equal to 2n. In various embodiments, such a transaction identifier combined with a source identifier and a home node identifier may form a globally unique transaction identifier.

Abstract: The present invention relates to a process for preparing an aqueous polymer dispersion containing polymer particles dispersed in an aqueous medium. The process includes providing first polymer particles; adding a hydrophobic polymerization blocker or a styrenic monomer polymerization blocker to the aqueous medium containing the first polymer particles; and preparing second polymer particles in the presence of the first polymer particles. The aqueous polymer dispersion contain first polymer particles and the second polymer that differ according to at least one attribute such as particle diameter, molecular weight, composition, glass transition temperature, or morphology; or contain polymer particles having a broad polydispersity. The aqueous polymer dispersion prepared by the process of this invention is useful in a wide range of applications, including paints, adhesive, binders for nonwovens, and binders for paper coatings.
