  • Patent number: 10152763
    Abstract: The present disclosure relates to a graphics processors and graphics processing systems. In the graphics processor, the rasterizer may operate to identify pairs of fragments for a primitive being rendered for which not all the sampling positions in the fragments are covered by the primitive. When the fragments reach the fragment shader, corresponding execution threads may be spawned for execution by the fragment shader to process the fragments. A first part of the fragment shader program that uses the helper threads of the thread groups may then be executed. There may then be a merge instruction in the fragment shader program which operates to cause the active threads of the thread groups to be merged into a single, combined thread group. Following this thread group merger, the remaining program steps of the fragment shader program may be executed for the merged thread group.

  • Patent number: 9697041
    Abstract: The invention discloses a method for dynamic interrupt balanced mapping method based on the current scheduling states of VCPUs. When the virtual I/O APIC of an SMP virtual machine needs to map a virtual interrupt into a VCPU of the virtual machine after receiving the virtual interrupt, a part of VCPUs in the active state are analyzed according to the scheduling states of all VCPUs of the current VM in a VMM scheduler, and the virtual interrupt is mapped into the active VCPUs to obtain lower interrupt processing delay. If a plurality of VCPUs are in the active state simultaneously, the interrupt load of each active VCPU is considered further, and the interrupt is mapped into the active VCPU with the current lowest current load to further ensure balancing of interrupt processing loads of all VCPUs, and therefore, the loads of VCPUs in the SPMP structure are more symmetrical to promote balancing of the overall performance of all VCPUs in the SMP structure.

  • Patent number: 8898364
    Abstract: The invention relates to a bus coupler which converts a network-specific telegram arriving from an external network to an internal data telegram which transmits only the payload data from the network-specific telegram. The internal data telegram also contains at least one state information field for internal control information. The internal data telegram is transferred from the bus coupler to an internal bus system to which multiple bus users are connected in series. Each bus user connected to the internal bus system is able to monitor, in a decentralized and preferably autonomous manner, the communication quality of the lower-level bus system, and to initiate actions, depending on the implementation, on the basis of the internal control information received from the bus coupler, the internal control information generated by the particular bus user, and/or the internal control information received from the directly adjacent bus users.

  • Patent number: 8880739
    Abstract: The efficiency of scaling of a network of computing devices can be improved by grouping highly-connected portions into deployment units wherein devices only have to be aware of other devices in the respective deployment unit. The various deployment units can be connected by a backbone mechanism. In some embodiments, the backbone utilizes a torroidal connection scheme to connect the backbone switches and pass routing protocol information. Host traffic can still utilize connections between tiers, such that standard routing and networking protocols can be utilized. In other embodiments, logical interfaces can be initialized in each backbone switch, such that each switch itself can function as a point backbone. The devices of the various deployment units then can communicate with each other via the point backbones using standard networking and routing protocols.

  • Patent number: 8868714
    Abstract: Known network management systems for managing traffic signals in a network store node/link parameter signals and traffic parameter signals and calculate solutions defining intermediate nodes/links situated between sources and destinations for transporting said traffic signals from said sources to said destinations via said intermediate nodes/links and calculate route information per solution. By storing node/link parameter signals and traffic parameter signals for several situations (like several predictions in the future) and calculating solutions for each situation and then selecting a solution per situation, the network management system will manage the network more advantageously, especially when solutions are compared with each other, and when a solution is selected per situation in dependence of comparison results (comprising similarities/differences between solutions of different situations).

  • Patent number: 8838692
    Abstract: XML appliances/routers may be organized to implement one or more XML distribution rings to enable XML documents/messages to be distributed efficiently. The rings may be logical or physical. The XML distribution rings enable the XML documents/messages to be exchanged without requiring the XML appliances/routers to run a routing protocol to determine how XML documents/messages should be distributed through the network. Documents may be transmitted in one way on the ring or may be transmitted in both directions around the ring to enable the ring to tolerate failure of an XML appliance/router. Each XML appliance/router will receive all XML documents/messages and will make routing decisions for those clients that have provided the XML appliance/router with XML subscriptions. The subscriptions may be formed according to the XPath standard or in another manner.
