Abstract: Methods and systems for neural network processing include configuring a physical network topology for a network that includes hardware nodes in accordance with a neural network topology, one of which is designated as a master node with any other nodes in the network being designated as slave nodes. One or more virtual neurons are configured at each of the hardware nodes by the master node to create a neural network having the neural network topology. Each virtual neuron has a neuron function and logical network connection information that establishes weighted connections between different virtual neurons. A neural network processing function is executed using the neural network.

Abstract: A neural network processing system having multiple layers is provided. Each layer includes a bidirectional Synaptic Network Channel (SNC) for concurrently transmitting weighted sums, yF(t)'s and xB(t)'s, as an elastic wave superposition of inputs, xF(t)'s and yB(t)'s, respectively. Each input is multiplied and added with corresponding weights w's encoded in variable splitters and combiners in forward and backward directions, respectively. Each layer includes unidirectional Signal Reshaping (SR) units, I's and L's for inference and learning, respectively, by generating inputs for a following layer in forward and backward directions from a current layer's weighted sums yF(t)'s and xB(t)'s, respectively. Each layer includes a Hybrid Coupler (HC) to connect the bidirectional SNC and the unidirectional SR units. Each layer includes a weight update unit to calculate each weight difference using an input yBi(t) or a weighted sum yFi(t) and an input xFj(t) to update a weight wij for a current layer.

Abstract: A memory controller is provided for accessing shared memory objects by read and write requests made to a memory. The memory controller includes a list for registering address locations of the shared objects in the memory, and having slots for a lock bit. The memory controller includes a read wait queue and a write wait queue for selectively inputting, outputting, holding, and purging requests. The memory controller includes a read initiated queue and a write initiated queue for selectively inputting and purging requests transferred from the read wait queue and the write wait queue, respectively, upon memory access initiation and completion. The memory controller includes a controller for controlling the wait queues using policies by determining which requests to output, hold, and purge, based on a list entry, a lock bit and TTL information set to each request upon a hold being applied thereto and decremented in each cycle.

Abstract: Methods and systems for memory-side shared caching include determining whether a requested memory access is directed to shared portion of memory by referencing a lock address list in a memory controller. If the requested memory access is for the shared portion of memory, it is determined whether an associated data object is present in a memory-side cache. If the associated data object is present in the memory-side cache, the memory-side cache is accessed. If the associated data object is not present in the memory-side cache, an external memory is accessed.

Abstract: A processor issues a command to a memory through an electrical memory link and performs a process according to the command through the electrical memory link. The processor issues a routing command to an optical circuit switch (OCS) through an OCS control line. In response to the routing command, the OCS establishes a routing of an optical memory link from the processor to the BDM. In response to the establishment of the optical memory link from the processor to the BDM, the processor (or a BDM (internal/dedicated) controller) switches from performing the process through the electrical memory link to performing a process through the optical memory link (continuously without an interruption between the successive processes). Corresponding systems are also disclosed herein.
