 MATAR is a C++ library that addresses the need for simple, fast, and memory-efficient multi-dimensional data representations for dense and sparse storage that arise with numerical methods and in software applications. The data representations are designed to perform well across multiple computer architectures, including CPUs and GPUs. MATAR allows users to easily create and use intricate data representations that are also portable across disparate architectures using Kokkos. The performance aspect is achieved by forcing contiguous memory layout (or as close to contiguous as possible) for multi-dimensional and multi-size dense or sparse MATrix and ARray (hence, MATAR) types. Results show that MATAR has the capability to improve memory utilization, performance, and programmer productivity in scientific computing. This is achieved by fitting more work into the available memory, minimizing memory loads required, and by loading memory in the most efficient order.
