Abstract: In the last decades, many algorithms have been developed to use high-performance computing
(HPC) techniques to accelerate the density matrix renormalization group (DMRG) method,
an effective method for solving large active space strong correlation problems. In this article, the
previous DMRG parallelization algorithms at different levels of the parallelism are introduced. The
heterogeneous computing acceleration methods and the mixed-precision implementation are also
presented and discussed. This mini-review concludes with some summary and prospects for future
works.
