  • Patent number: 11868880
    Abstract: An interconnect topology for communication between GPUs in a computing system is determined. A quantity of directed spanning trees are generated for transmitting data between the GPUs using the interconnect topology and packed. The directed spanning trees define the connections between GPUs that are to be utilized for the transmission and the amount of data to be transmitted on each connection. Program code is generated for implementing the data transfer defined by the directed spanning trees. When the program code is executed, the directed spanning trees are used to pipeline the transmission of chunks of data, such as model parameters used during data-parallel DNN training, between the GPUs. The program code can also determine an optimal chunk size for data to be transferred between the GPUs.

  • Patent number: 11789072
    Abstract: A clock monitor circuit includes a monitor and a tunable counter. The monitor can monitor a clock under test. The tunable counter can count an integer according to a reference clock and set a target number. If a stable signal relative to the clock under test is toggled, the tunable counter can switch the target number from a large number to a small number. The tunable counter can perform an automatic detection process, so as to transmit a check signal to the monitor. In response to the check signal, if the clock under test is undetectable, the monitor will not transmit any confirmation signal back to the tunable counter, and the tunable counter will gradually increase the integer. When the integer is equal to the target number, the tunable counter generates a failure signal.

For example, the indicated service may correspond to at least one of: a mobile originated (MO) voice communication, a circuit switched fallback (CSFB) supplementary service (SS), or a MO short message service (SMS). The RRC layer may receive a signal from a network indicating that one or more services provided by the network are allowed. The RRC layer may send a connection request to the network for the service sought by the NAS if that service is one of the one or more services allowed.

  • Patent number: 11729864
    Abstract: A network server selects a gateway, from among a plurality of alternative candidate gateways, to use for downlink wireless communication to an end node (EN) based on additional factors in addition to RSSI. Exemplary additional factors include: SNR, gateway loading, message loading, backhaul network loading, device type, application type, application priority, operator preferences, device/application black-lists, white-lists, and red-lists, number of devices, number of transmitting devices in a given time interval, operator rules and priorities. In some embodiments, the network server calculates a composite weighted metric (CWM) for each of the alternative candidate gateways which may be used for downlink, subject to operator policy rules, and selects to use a gateway based on the results, e.g. selects the gateway with the highest CWM.

  • Patent number: 11729092
    Abstract: The disclosed invention provides system and method for multi-path mesh network communications. The network system utilizes multiple communication paths and linearly encoded and disassembled packets through mathematical coding techniques that respectively travel the communication paths. The system includes an encoder, a transmitter, a decoder and a receiver. The encoder receives data from an external source and linearly encodes and simultaneously disassembles the data to generate copackets. None of the individual copackets contain decodable information of the data. The transmitter is coupled to the multiple communication paths and respectively transmits the copackets through different communication paths. The receiver receives the copackets transmitted through the communication paths. The decoder decodes available copackets and reassembles the data from the available copackets if a number of the available copackets are no less than a mathematically calculated number.

  • Patent number: 11726933
    Abstract: An I/O server service interacts with multiple containerized controller services each implementing the same control routine to control the same portion of the same plant. The I/O server service may provide the same controller inputs to each of the containerized controller services (e.g., representing measurements obtained by field devices and transmitted by the field devices to the I/O server service). Each containerized controller service executes the same control routine to generate a set of controller outputs. The I/O server service receives each set of controller outputs and forwards an “active” set to the appropriate field devices. The I/O server service and other services, such as an orchestrator service, may continuously evaluate performance and resource utilization in the control system, and may dynamically activate and deactivate controller services as appropriate.
