A physical system is simulated using a model including a plurality of elements in a mesh or grid. The elements are divided into partitions processed by different processing units. For some time steps, state data is transmitted between partitions and used to calculate flux data for updating the state of edge elements of the partitions.

Alternatively, flux data is obtained by processing state variables of an edge element and past flux data using a machine learning model, such as a DNN. Whether to suppress transmission of state data may be determined based on one or both of (a) uncertainty in an output of the machine learning model (e.g., Bayesian neural network) and (b) complexity of model of the physical system (e.g., spatial or temporal gradients).

The memory controller includes a command queue and a sparse element processor. The command queue is for receiving and storing the memory access requests including a first memory access request including a small element request. The sparse element processor is for causing the memory controller to issue a second memory access request to the memory system in response to the first memory access request with a density greater than a density indicated by the first memory access request.
An electronic device includes a processor having processor circuitry and a leader memory controller, a controller coupled to the processor and having a follower memory controller, and a memory. The processor circuitry is operable to access the memory by issuing memory access requests to the leader memory controller. The leader memory controller is operable to complete the memory access requests using the follower memory controller to issue memory commands to the at least one memory die.
A data processing node includes a processor element and a data fabric circuit. The data fabric circuit is coupled to the processor element and to a local memory element and includes a crossbar switch. The data fabric circuit is operable to bypass the crossbar switch for memory access requests between the processor element and the local memory element.
A method for forming a semiconductor assembly that includes forming a first set of layers on a first wafer, where one or more layers of the first set includes one or more devices of the semiconductor assembly. The method further includes forming a second set of layers on a second wafer, where one or more layers of the second set include connections between one or more of the devices of the semiconductor assembly. The method additionally includes coupling a layer of the first set to a layer of the second set using metal to metal hybrid bonding.
