The AXT format has been published in the paper "A new AXT format for an efficient SpMV product using AVX-512 instructions and CUDA" in the journal Advances in Engineering Software. The paper can be found on the following link: https://www.sciencedirect.com/science/article/pii/S0965997821000260 .

The AXT format's software is part of the AXT_SPL library registered under a GPL license. The Universidad de Santiago de Compostela partially owns the intellectual rights.

This project contains the code to perform the SpMV product on NVIDIA's GPUs.
