Batch sequence hybrid parallel method, device, storage medium and program product

This application provides a batch-sequence hybrid parallel method, device, storage medium, and program product, relating to the field of artificial intelligence chip technology. The method includes: obtaining the original batch size and original sequence length of the original tensor; when the ratio of the original batch size to the sequence parallelism is not an integer, performing a shape transformation operation on the original tensor to obtain a target tensor, such that the target batch size of the target tensor in the batch dimension is an integer multiple of the sequence parallelism. This allows the target tensor to be uniformly divided into M first sub-tensors in the batch dimension, and the M first sub-tensors are distributed to M devices for parallel computation to obtain a first computation result. During the computation process, each device does not need to store the entire target tensor, but only needs to store the allocated first sub-tensors, thus greatly reducing memory usage; when M devices perform parallel computation on the target tensor, computational efficiency can be greatly improved, thereby enhancing the overall performance of model training.

Systems and methods for selective shape transformation of 3d-printed materials

Shape-restoring materials, as well as techniques for generating shape-restoring materials, are described. An example method includes generating a construct by exposing, to UV-visible light, a resin comprising a globular protein, a water-soluble co-monomer, light-to-heat converting nanoparticles, water, and a photoinitiator. At least a portion of the water is removed from the construct. The construct is converted from a first shape to a second shape by applying a force to the construct. The construct is reverted to the first shape in response to being exposed to NIR light, due to the absorption of the NIR light by the nanoparticles.
