Abstract: Techniques for exchanging compressed gradient data within a distributed system are disclosed. A set of gradients are computed at a first worker node of the distributed system using a neural network model and a set of weights associated with the neural network model. Each of the set of gradients having a value less than a threshold is clipped, resulting in non-clipped data elements and clipped data elements.

Compressed data is generated based on the non-clipped data elements. The mapping and the compressed data are transmitted from the first worker node to a second worker node of the distributed system.

Abstract: A first resistivity value and a correlation function relating thickness of a conductive layer having the first resistivity value to a signal from an in-situ monitoring system are stored. A second resistivity value for a conductive layer on a substrate is received.

Abstract: To reduce the storage size of weight tensors and speed up loading of weight tensors from system memory, a compression technique can be employed to remove zero values from a weight tensor before storing the weight tensor in system memory. A sparsity threshold can be enforced to achieve a compression ratio target by forcing small weight values to zero during training. When the weight tensor is loaded from system memory, a direct memory access (DMA) engine with an in-line decompression unit can decompress the weight tensor on-the-fly. By performing the decompression in the DMA engine, expansion of the weight values back to the original weight tensor size can be carried out in parallel while other neural network computations are being performed by the processing unit.

The operating process is simple, the cost of the plating solution is largely reduced, and the problem that the coating on the inner wall of the thin-walled workpiece is difficult to repair due to stripping is solved.
