Abstract: A primary controller has authority of a cache line associated with a fetch and manages a second cache line request from a different and non-associated secondary requesting entity. A secondary controller, associated with the secondary requesting entity, is granted authority of the cache line and further manages multiple subsequent simultaneous or overlapping requests for the cache line from different non-associated subsequent requesting entities by maintaining authority of the cache line, by granting read-only access to the cache line to respective subsequent controllers, each associated with a different subsequent requesting entity, and by passing a non-authority token to each of the respective subsequent controllers.

Abstract: Embodiments are for using a decentralized hot cache line tracking fairness mechanism. In response to receiving an incoming request to access a cache line, a determination is made to grant access to the cache line based on a requested state and a serviced state used for maintaining the cache line, a structure comprising the requested and serviced states. In response to the determination to grant access to the cache line, the requested state and the serviced state are transferred along with data of the cache line.

Abstract: A computer system includes a processor core and a memory system in signal communication with the processor core. The memory system includes a first cache and a second cache. The first cache is arranged at a first level of a hierarchy in the memory system and is configured to store a plurality of first-cache entries. The second cache is arranged at a second level of the hierarchy that is lower than the first level, and stores a plurality of second-cache entries. The first cache maintains a directory that contains information for each of the first-cache entries. The second cache maintains a shadow pointer directory (SPD) that includes one or more SPD entries that maps each of the first-cache entries to a corresponding second cache entry at a lower-level cache location.

Abstract: Embodiments include processing commands on multiprocessor chip having a plurality of nodes that are interconnected via a clockwise ring network and a counterclockwise ring network. Aspects include receiving a command for execution and based at least in part on a determination that the clockwise ring network and the counterclockwise ring network are both available for transmission, performing a bidirectional execution of the command. The bidirectional execution includes transmitting a first warning signal on the clockwise ring network and a second warning signal on the counterclockwise ring network, transmitting the command on the clockwise ring network a first number of clock cycles after the first warning signal, and transmitting the command on the counterclockwise ring network a second number of clock cycles after the second warning signal.

Abstract: Embodiments are for preemptive tracking of remote requests for decentralized hot cache line fairness tracking. Authority is requested for a cache line in conjunction with querying for outstanding requests for the cache line. One or more responses are received regarding the outstanding requests for the cache line. In response to receiving the one or more responses regarding the outstanding requests and in advance of receiving the authority for the cache line, the outstanding requests are preemptively tracked in a requested structure associated with the cache line.

Abstract: A computer-implemented method is provided. The method includes determining whether a rejection of a request is required and determining whether the request is software forward progress (SFP)-likely or SFP-unlikely upon determining that the rejection of the request is required. The method also includes executing a first pseudo random decision to set or not set a requested state of the request in an event the request is SFP-likely or SFP-unlikely, respectively, and rejecting the request following execution of the second pseudo random decision.

Abstract: A method for managing designated authority status in a cache line includes identifying an initial designated authority (DA) member cache for a cache line, transferring DA status from the initial DA member cache to a new DA member cache, determining whether the new DA member cache is active, indicating a final state of the initial DA cache responsive to determining that the new DA member cache is active, and overriding a DA state in a cache control structure in a directory. A method for managing cache accesses during a designated authority transfer includes receiving a designated authority (DA) status transfer request, receiving an indication that a first cache will invalidate its copy of the cache line, allowing a second cache to assume DA status for the cache line, and denying access to the first cache’s copy of the cache line until invalidation by the first cache is complete.

Abstract: Systems and methods for generating three-dimensional models with correlated three-dimensional and two dimensional imagery data are provided. In particular, imagery data can be captured in two dimensions and three dimensions. Imagery data can be transformed into models. Two-dimensional data and three-dimensional data can be correlated within models. Two-dimensional data can be selected for display within a three-dimensional model. Modifications can be made to the three-dimensional model and can be displayed within a three-dimensional model or within two-dimensional data. Models can transition between two dimensional imagery data and three dimensional imagery data.

Abstract: The present invention relates to dihydrocyclopenta-isoquinoline-sulfonamide derivatives of formula (I), processes for preparing them, pharmaceutical compositions containing them and their use in treating disorders caused by IgE (such as allergic responses, non-allergic mast cell responses or certain autoimmune responses), and in particular disorders caused by the interaction of IgE with the Fc?RI receptor.

Abstract: Embodiments are for special tracking pool enhancement for core L1 address invalidates. An invalidate request is designated to fill an entry in a queue in a local cache of a processor core, the queue including a first allocation associated with processing any type of invalidate request and a second allocation associated with processing an invalidate request not requiring a response in order for a controller to be made available, the entry being in the second allocation. Responsive to designating the invalidate request to fill the entry in the queue in the local cache, a state of the controller that made the invalidate request is changed to available based at least in part on the entry being in the second allocation.

Abstract: A series of substituted 4,4-difluorocyclohexyl derivatives as defined herein, being potent modulators of human IL-17 activity, are accordingly of benefit in the treatment and/or prevention of various human ailments, including inflammatory and autoimmune disorders.

Abstract: Systems and techniques for processing and/or transmitting three-dimensional (3D) data are presented. A partitioning component receives captured 3D data associated with a 3D model of an interior environment and partitions the captured 3D data into at least one data chunk associated with at least a first level of detail and a second level of detail. A data component stores 3D data including at least the first level of detail and the second level of detail for the at least one data chunk. An output component transmits a portion of data from the at least one data chunk that is associated with the first level of detail or the second level of detail to a remote client device based on information associated with the first level of detail and the second level of detail.
