Multidimensional Array References for the C++ Standard Library

Explore the proposed array_ref library for C++ in this comprehensive CppNow conference talk. Dive into the world of multidimensional arrays, a crucial data structure for science and engineering applications that currently lacks proper representation in the C++ standard library. Learn about array_ref, a performance-oriented multidimensional array reference proposed for inclusion in future C++ standards or the C++ Library TS. Discover how array_ref provides a powerful and generic abstraction supporting user-defined layouts and access semantics, making it ideal for interoperability with existing applications and other programming languages, as well as addressing special memory regions like GPU memory. Examine the challenges faced in creating an elegant and expressive interface without sacrificing performance or breaking the zero-overhead principle. Gain insights into array_ref's powerful subarray interface designed for performant iteration of multi-dimensional arrays. Understand how to use array_ref to work with multi-dimensional data structures and manage special memory exposed by new architectures. Get started with a stand-alone C++14 implementation of array_ref developed by Bryce, available under the Boost Software License.
