  • Publication number: 20240119008
    Abstract: Works in the literature fail to leverage embedding access patterns and memory units' access/storage capabilities, which when combined can yield high-speed heterogeneous systems by dynamically re-organizing embedding tables partitions across hardware during inference. A method and system for optimal deployment of embeddings tables across heterogeneous memory architecture for high-speed recommendations inference is disclosed, which dynamically partitions and organizes embedding tables across fast memory architectures to reduce access time. Partitions are chosen to take advantage of the past access patterns of those tables to ensure that frequently accessed data is available in the fast memory most of the time. Partition and replication is used to co-optimize memory access time and resources.

  • Publication number: 20240112095
    Abstract: The disclosure generally relates to an FPGA-based online 3D bin packing. Online 3D bin packing is the process of packing boxes into larger bins-Long Distance Containers (LDCs) such that the space inside each LDC is used to the maximum extent. The use of deep reinforcement learning (Deep RL) for this process is effective and popular. However, since the existing processor-based implementations are limited by Von-Neumann architecture and take a long time to evaluate each alignment for a box, only a few potential alignments are considered, resulting in sub-optimal packing efficiency. This disclosure describes an architecture for bin packing which leverages pipelining and parallel processing on FPGA for faster and exhaustive evaluation of all alignments for each box resulting in increased efficiency. In addition, a suitable generic purpose processor is employed to train the neural network within the algorithm to make the disclosed techniques computationally light, faster and efficient.

  • Patent number: 11913852
    Abstract: A sensor system includes a pump, a valve supplied from the pump, a sensor fixed relative to the pump, a nozzle supplied from the valve and aimed at the sensor, and a computer communicatively coupled to the pump, the valve, and the sensor. The computer is programmed to instruct the pump to operate; while the pump is operating, instruct the valve to close; receive data from the sensor while the pump is operating and the valve is instructed to be closed; and set a flag upon determining, based on the data received from the sensor, that the nozzle is outputting fluid onto the sensor.

  • Publication number: 20230325647
    Abstract: This disclosure relates generally to method and system to estimate performance of session based recommendation model layers on FPGA. Profiling is easy to perform on software based platforms such as a CPU and a GPU which have development frameworks and tool sets but on systems such as a FPGA, implementation risks are higher and important to model the performance prior to implementation. The disclosed method analyses a session based recommendation (SBR) model layers for performance estimation. Further, a network bandwidth is determined to process each layer of the SBR model based on dimensions. Performance of each layer of the SBR model is estimated at a predefined frequency by creating a layer profile comprising a throughput and a latency in one or more batches. Further, the method deploys an optimal layer on at least one of a heterogeneous hardware based on the estimated performance of each layer profile on the FPGA.
