Distributed tensor computations

Definition

Distributed tensor computations refer to the methods and techniques used to perform operations on tensors across multiple computing units or nodes in a network. This approach allows for efficient handling of large-scale tensor data by leveraging parallel processing capabilities, thereby reducing computational time and resource usage. The ability to distribute these computations is crucial in various fields such as machine learning, physics simulations, and data analysis, as it facilitates the management of high-dimensional data and complex algorithms.
