Abstract: Disclosed are systems and methods that implement efficient engines for computation-intensive tasks such as neural network deployment. Various embodiments of the invention provide for high-throughput batching that increases throughput of streaming data in high-traffic applications, such as real-time speech transcription.

Some embodiments allow for performing steaming classification using pre-processing. The gains in performance allow for more efficient use of a compute engine and drastically reduce the cost of deploying large neural networks at scale, while meeting strict application requirements and adding relatively little computational latency so as to maintain a satisfactory application experience.

Abstract: A traffic manager is shared amongst two or more egress blocks of a network device, thereby allowing traffic management resources to be shared between the egress blocks. Among other aspects, this may reduce power demands and allow a larger amount of buffer memory to be available to a given egress block that may be experiencing high traffic loads. Optionally, the shared traffic manager may be leveraged to reduce the resources required to handle data units on ingress. Rather than buffer the entire unit in the ingress buffers, an arbiter may be configured to buffer only the control portion of the data unit. The payload of the data unit, by contrast, is forwarded directly to the shared traffic manager, where it is placed in the egress buffers. Because the payload is not being buffered in the ingress buffers, the ingress buffer memory may be greatly reduced.

To send the report, the data plane circuit in some embodiments duplicates the particular data message, stores it in the duplicate data message information regarding the detected queue congestion, and sends the duplicate data message to the external data collector.

Abstract: A computing system uses a memory for storing data, one or more clients for generating network traffic and a communication fabric with network switches. The network switches include centralized storage structures, rather than separate input and output storage structures. The network switches store particular metadata corresponding to received packets in a single, centralized collapsing queue where the age of the packets corresponds to a queue entry position. The payload data of the packets are stored in a separate memory, so the relatively large amount of data is not shifted during the lifetime of the packet in the network switch. The network switches select sparse queue entries in the collapsible queue, deallocate the selected queue entries, and shift remaining allocated queue entries toward a first end of the queue with a delay proportional to the radix of the network switches.

Abstract: A method, system and computer-usable medium are disclosed for performing a network traffic combination operation. With the network traffic combination operation, a plurality of input queues are defined by an operating system for an adapter based upon workload type (e.g., as determined by a transport layer). Additionally, the operating system defines each input queue to match a virtual memory architecture of the transport layer (e.g., one input queue is defined as 31 bit and other input queue is defined as 64 bit).

Thus, data copies are eliminated and memory consumption and associated storage management operations are reduced for the smaller bit architecture communications while allowing the operating system to continue executing in a larger bit architecture configuration.
